Band saw blades for metal manufacturing

Specifications

In order for it to be convenient to work on the saw with your own hands, it is necessary to select the technical parameters of the blade as accurately as possible.

The cut-off band saw is also characterized by parameters such as feed and speed.

You should set the required tension with your own hands, guided by the design features of the tool.

The free wheeling of the saw ensures the correct tension, as well as the setting, which can be of several different types.

So, for steel, as well as non-ferrous metals, cutting is done with a standard wiring.

Cutting profiles, pipes, as well as other parts with a variable cross-section is carried out with variable wiring.

In turn, cutting thin products with a small diameter is carried out by wave routing. When choosing a blade, one should also be guided by the shape of the tooth, which can be of different types.

It should also be remembered that the sharpening of this tool with your own hands is carried out in a special way according to a certain technology.

There are many other nuances that are individual in nature, in relation to the type of equipment used.

Manufacturers currently offer a large selection of band saws that have different characteristics of their work.

The equipment under the Corvette brand has proven itself well. Corvette offers a wide range of band saws for various purposes.

When using the Corvette band saw, the cut is smooth and straight.

Corvette equipment is characterized by high performance and reliability, as well as high technical parameters, which ensure high quality of the work performed at the output.

Some models of saws under the Corvette brand are equipped with a rotary vise, which makes it easier to do the corresponding work with your own hands.

Band saw blade production rates, the difference between bi-metal and carbide.

The Jet metal band saw also performs well.

This tool is designed to work with various types of materials and is characterized by high performance and optimal reliability.

How to choose a band saw for metal?

Currently, [metal band saws] are one of the most important blank production devices. From the article you will learn how to choose the right tool, as well as understand why timely sharpening of the tool, the brand of the manufacturer and the cost when choosing a saw are so important.

Due to their variety and the most optimal cutting modes, such saws provide not only the highest productivity, but also several times reduce the cost of this type of processing.

The main element of this category of saws are blades, which are made mainly of high quality carbon steel.

Such blades allow you to successfully work with both alloyed and non-alloyed metal alloys. To choose a saw, you need to decide in advance which type of blade is more comfortable to work with.

At its core, the band saw is the main working body of the band saw equipment.

band, blades, metal, manufacturing

The blades used in this process are a closed contour with sharpened teeth of the correct shape.

These versatile cutting devices for various types of materials are widely used in a wide variety of industrial applications.

They can be found at various construction sites. Band saws are a must-have for the aeronautical and automotive industries.

In addition, they are also used in small production halls to solve a wide variety of tasks.

The vertical cutting band saw is currently represented in the relevant market in a large assortment.

In order to choose the right tool, it is necessary to accurately represent its main purpose.

Main operating parameters

The selection of a band saw should be based on the characteristics of the main production, as well as its power capabilities. For example, the Jet metal band saw is one of the best in terms of price-performance ratio.

It should be remembered that using this type of blade, you can cut almost all types of metal, as well as some other materials with your own hands.

Before starting work, it is necessary to check the tension of the blade, as well as its sharpness.

If necessary, the tool should be sharpened, and only after that the necessary tension is carried out directly on the equipment itself.

When choosing a band saw, price should not be a factor. Also, do not expect that the higher the price, the better the quality of the tool.

It is necessary to focus on the average. The performance of this tool is of great importance.

In the event that the band saw will be used in a small production, it is recommended to make a choice in favor of universal devices, the price of which is within acceptable limits.

In large industries, it is better to use more functional models of band saws, although their price will increase slightly.

Also pay attention to the cutting material.

In the case when a cutting saw is required for processing simple types of structures, then you should choose from less functional devices, the price of which is within acceptable limits.

In addition, they are great for working with a wide variety of materials.

If you need to regularly carry out work on the processing of complex material, it is recommended to choose a specialized saw.

You can opt for products with increased tooth rigidity or diamond-coated.

Of course, the price of such a band saw will be slightly higher, but it should be borne in mind that the quality of work and the service life of the tool will increase several times.

One of the main indicators for tape-type slabs is the tooth pitch. In many respects, not only the service life of the tool itself, but also the quality of the work performed depends on the tooth pitch.

In this case, it should be borne in mind that the higher the thickness of the workpiece, the smaller the step should be and vice versa.

It is also necessary to pay attention to how the tool is sharpened. How to work correctly on a band saw is described in the video posted above.

Some features

In most cases, band saws are used to cut all kinds of metal rods, pipes, as well as fittings.

They perform straight as well as oblique cuts in the workpiece.

The main cutting tool in saws of this type are blades, which are characterized by tooth stiffness, and in addition, the ability to work on a particular metal and productivity.

There are other parameters of the band saw blade operation that you need to know in order to choose the right tool.

How to manufacture band saw blade?

It should be noted that the price of such equipment depends, as a rule, on its performance and the manufacturer’s firm.

So, among the leaders of the domestic market for this type of equipment, there is a great demand for products under the Corvette brand.

The price of Corvette saws is within affordable limits and fully corresponds to their quality. In addition, some craftsmen assemble fairly productive band saws with their own hands.

Cutting surfaces with band-type saws is quite simple, and you do not need to have special qualifications to work on equipment of this class.

Cutting metal products using band saws has a number of advantages when compared with the use of a similar tool.

First of all, it should be noted that band-type saws give a clear and accurate cut at the output, which practically does not need further processing or grinding.

This allows not only to save working time, but also to reduce the cost of purchasing additional tools.

It should also be noted that such manual cutting of metals is distinguished by high productivity, moreover, the service life of the blade itself is quite long.

When working with a band saw, a minimum amount of production waste is generated in the form of metal shavings.

In general, a band-type saw is a fairly versatile tool in its class for DIY work. Many other materials such as plastic and wood are easily cut with it.

It is easy to work on such equipment even with your own hands. The video posted above shows in detail the process of working on a band saw.

Tips & Tricks

Sharpening of band saws should be done using special equipment.

For this, a special machine is used, which makes it possible to do the necessary work with your own hands as soon as possible.

How to sharpen band saws with your own hands is described in detail in the video, which is posted below.

It should be remembered that when working with a saw, you must follow the safety rules. Carefully adjust the tool and control the blade tension. Optimal sharpening of the tool also plays an important role, it is thanks to her that manual work on the Corvette saw is so comfortable and enjoyable.

There is such a concept as the rest of the canvas, which characterizes the fatigue of the material during intensive work. If long-term work on the saw is planned, then it is recommended to use two hotel blades.

When choosing a saw, it is recommended to pay attention not only to its cost, but also to all technical characteristics, as well as to the name of the manufacturer. It should be remembered that manual work with a band saw for metal with your own hands should be comfortable. Naturally, the price of the tool affects the capabilities of the tool, but it should not become the main criterion for choosing a saw.

Of great importance is the material from which the canvas is made. The video below shows the Jet saw in action.

Base

  • Since the band saw must be strong, it is necessary to prepare plywood with a thickness of at least 15 mm. We cut off four pieces 550 mm long and 23 mm wide.
  • Next, we make the markup using a pre-created stencil, or you can make the markup directly on the workpiece. The two plates located inside must have a niche for the tunable mechanism. For external parts, a through groove must be drawn. The amount of vertical adjustment will depend on the dimensions of this slot. Next, you need to mark the through hole for the drive lower shaft. In addition, we need a surface for a saw table, the dimensions of which in the width of the table will not exceed 150 mm. In all blanks, it is necessary to cut a square between the circles in height equal to 15-20 cm, and not exceeding 15 cm in width.
  • Using a jigsaw, you need to cut out the necessary parts, as well as the adjustment groove of the upper pulley, then drill a hole for the lower drive shaft.
  • Next, you need to collect the future foundation. For assembly, PVA glue or any other joiner’s glue is used. We apply it in an even layer on all the surfaces to be glued, then we apply the parts to each other, avoiding inaccuracies. Fixation of products must be performed with clamps, since for high-quality gluing, a tight fit of the blanks is necessary. Until the glue is completely dry, it is necessary to withstand a day.
  • We install bearings for the lower drive shaft.

Band saw rules

A large volume of processed materials requires the installation of a blade with large teeth on the machine. The best option is the use of universal band saws.

  • with a large size of the workpiece to be processed, it should be installed on a band saw with large teeth; it is better to use cutting belts of the universal type. This will eliminate the need to change the blade when processing various materials;
  • Determine the location of the machine and securely fix it on a static surface, avoiding vibrations during operation. The room in which the band saw will be installed must be well ventilated.
  • After finishing work, remove the saw band and, accordingly, tighten it only before work. This will extend the useful life of the canvas.
  • Every two hours of operation, turn off the band saw and allow the motor, in this example the drill, to rest while checking for faults. Compliance with this rule will protect the worker from injury, and the tool from overheating.
  • Check the setting of the cutting teeth from time to time.

Homemade jigsaw-heat cutter

The jigsaw is a very common tool. However, when working with it, you have to face certain difficulties: the file then breaks, then jumps out of the clamps, when cutting along a curved contour, it often twists, which makes it difficult to maintain the required direction. Much more convenient is a homemade electric thermal jigsaw, which allows you to cut parts of any shape, both from plywood (wood) and from organic glass, ebonite and other combustible or melting materials. Although it also has some disadvantages.

Which canvas should you choose?

Do-it-yourself band saws can be made from those materials that can be found at home. However, the canvas will have to be bought. Before that, it is worth deciding exactly what it should be. To do this, you need to know what you are going to cut. So, there are such canvases:

Bimetallic. They are used for cutting sufficiently strong alloys, stainless steel. At the same time, you can be sure that the tape will not burst.

Diamond. They are used when it is necessary to process marble, granite, quartz and other hardest materials.

Carbide. They can be used for cutting alloys that are quite difficult to work with.

Tool steel. Such canvases are most often used at home or in small workshops. They are most suitable for working with simple materials.

Saw blade (band) tensioning mechanism

  • To manufacture the band saw tension mechanism, you need to make a bar, the dimensions of which will correspond to the niche in the saw body. A hole is drilled at the end of the bar for the stud and the foot. Bearing housings are cut on both sides.
  • We insert the hairpin and fix it in the bar. It must hold firmly in the hole. To increase the strength of the fastening, before inserting the hairpin, apply PVA glue to its surface, and in addition, you need to fix the hairpin with a self-tapping screw or screw.
  • Next, the shaft bearings and the fixing sleeve are installed.
  • With the help of a screw in the case, the saw blade tensioning mechanism will be rigidly fixed.
  • It is necessary to install a handle on the hairpin, the rotation of which will allow you to change the depth of immersion of the bar into the base, thereby changing the distance between the pulleys. this is how the belt is tensioned.

Making a band saw

Tools:

Pulleys

While the glue of the base dries, we proceed to the manufacture of moving elements, namely pulleys. The whole process of their manufacture is reflected in the given photos.

  • On a sheet of plywood 15 mm thick, you need to mark the contours. a circle with a diameter of 150 mm.
  • Cut the workpieces with a jigsaw along the outlined contours and drill a hole in the center of the circle.
  • Even the most precise and accurate sawing will not give the workpiece perfectly correct shapes, so it is necessary to grind the ends. For this, a grinding machine with a table at 90 degrees in relation to the processed plane will be used. If you do not have a suitable tool, you can grind the edge with a hand sander or a homemade screwdriver attachment with a grinding attachment. The workpiece is fixed with a bolt or self-tapping screw to some base. Thus, when it is fed to the grinding wheel and rotated around the axis, a perfectly flat wheel is obtained.
  • After processing the pulley on a grinder, you need to wrap its ends with insulating tape in several layers, and you can also use rubber from bicycle cameras.

Our company sells the German Eberle band saw blades in the best traditions.

These band saw blades combine strength and flexibility. This significantly increases their service life compared to other analogs and adds the ability to process a larger amount of metal.

Blades are able to process material of different hardness and shape, which makes them more popular among metalworking organizations.

Why do you need a band saw blade for metal?

The saw blade is a special device with a metal toothed edge. It is used on band saws for processing metal, wood and other materials.

Metal processing with metal cutting band saws has many advantages. In general, industrial bimetallic strips for metal are widely used to increase the productivity of metalworking and save time.

To ensure optimal use of the band saw blade for metal, it is recommended to purchase a special band saw blade that will match the material and the volume of processing. This has a huge impact on the increase in the service life and operation of the band saw machines.

over, to increase productivity, it is recommended to operate the blade with the appropriate coolant for the metal band saw and control the recommended operating mode.

The tape blade allows you to reduce the time spent on metal processing, thereby allowing you to obtain high-quality material cuts.

The blades of the tools are made of high-carbon steel with an extremely precise sharpening of the teeth.

The blade will be an excellent tool for cutting straight and curved lines, as well as irregular metal shapes.

Band saws for cutting metals

For modern band saw technologies for metal processing, the market today offers band saws made of carbon steel and bimetallic. with spring base and HSS or carbide tines. The variety of design parameters of band saws in combination with the use of optimal cutting conditions allows to provide high productivity and reduce the cost of the technological process of processing on band saws in comparison with other methods of separating blanks.

Durability of band saws.

Productivity when cutting with bimetallic band saws is in the range of 10-25 cm? / Min, when cutting high-alloy alloys and difficult-to-machine materials, and 45-70 cm? / Min, when cutting structural steels. For each tool, there is a certain relationship between productivity and tool life, which is shown in table 1. (The data is given for blanks with a diameter of 100 mm, cut by saws 27×0.9)

In addition to the resistance of the saw tooth itself to wear, it should also be noted that the blade itself is resistant to cyclic alternating loads arising from the movement of the saw itself in the band mechanism of the band saw machine.

For saws of most manufacturers (subject to the technological process of saw manufacturing. from the workpiece to the packaging and storage conditions of the finished blade), the service life of the blade is within 140-160 hours of equipment operation. Removing the saw during breaks in the equipment for relaxation, slightly increases the service life of the blade.

The durability of the sawtooth is significantly influenced by the correct pitch of the band sawtooth. The tables below show the dependence of the saw pitch on the diameter of the material being cut. It should be noted that when cutting with a package, the wall thickness should be considered the total thickness of the metal that the saw tooth will pass.

Technical specifications.

To achieve optimal conditions when working with certain groups of materials and the shape of workpieces, it is necessary to accurately select the parameters of the saw blade: pitch, shape and setting of the tooth, as well as the operating modes of the band saw machine. speed and feed of the band saw.

Teeth Per Inch (TPI) Teeth Per Inch determines the blade pitch and can range from 1 to 32 for constant pitch saws and 10/14 to 0.75 / 1.25 for variable pitch saws. Firms. band saw manufacturers and their distributors include a pitch guide when sawing solid workpieces, pipes and profiles.

Constant step (for example 14)

Variable pitch (e.g. 8/12)

Saw band speed.

The cutting mode is determined by several parameters, primarily the workpiece material. It is necessary to take into account which group of steels and alloys it belongs to. You also need to know the size of the workpiece to be processed and choose the right tooth pitch. At the same time, it is of no small importance which company produced the canvas. Bandsaw sellers provide recommendations for choosing the optimal band saw speed for a particular type of equipment. The equipment produced by the American company JET has proven itself well. models with the VS index are equipped with a stepless speed variator, which makes it possible to optimally select the cutting speed for a specific group of material. In addition, these machines are equipped with a built-in strain gauge to control the saw tension, which is also important for increasing the saw’s service life.

Determination of the saw blade feed speed. Optimal cutting requires each tooth of the band saw to cut a certain chip thickness. In practice, the feed is selected according to the recommendations of the equipment manufacturers or according to the type of chips that are obtained during cutting. For thin or dusty chips, increase the blade feed speed or decrease the cutting speed. Lightly curling chips indicate the correct cutting mode. Thick or blue chip indicates excessive feed rate or increase cutting speed.

In this article, I will tell you in detail about band saws for metal, all the advantages and disadvantages, how to use them, how to choose the tooth pitch, what kind of saws there are, and much more. Here’s a bunch of technical information. so first things first.

Band saw blades for metal, band saws for metal. HOW AND WITH WHAT THEY ARE EATED!

Band saws. what is this tool?

The purpose of the band saws is to cut various materials: wood, metal, plastic or foam. As a working tool, a ring-shaped closed saw blade that rotates quickly is used. The band saw is made of carbon steel or hard alloys. In some models, blades of 2 metals (bimetallic) are used, as well as blades, on the teeth of which hard alloy solders are applied. The width of the working blade varies from 13 to 80 mm. If the cutting method is vertical, narrower (from 6 mm) blades can be used.

The scope of the tool is wide enough: home workshops, band machines, sawmills. With this device, you can make a cut of complex shape and varying degrees of accuracy, depending on the class of equipment. For example, a parabolic or elliptical cut is possible. The band saw is also suitable for making straight and corner cuts on pipes or metal rods. The tool is also used in furniture production: both for the manufacture of miniature products and for cutting long thick boards.

Features of band saws for metal

Cutting steel or other types of metals involves the use of special equipment, special working blades. The main feature of the belt-type equipment used for working with metal from woodworking counterparts is the relatively low speed of the working blade and the equipment with high-power motors. All band machines for metal are divided into 4 classes. Both the scope of its use and the cost depend on the belonging of the model to a certain category. Consider the characteristics of the classes:

  • first. Quite expensive equipment. Suitable for processing metals of various degrees of hardness: from aluminum to high-alloy steels. Products are distinguished by large sizes and weight. If the machine is intended to work with hard metals, then a cooling system with a special liquid is provided. Almost all equipment that belongs to the first class is automated;
  • second. The functionality of these band saws is the same as that of the previous type of equipment, but in terms of accuracy they are somewhat inferior to it. There are automatic and semi-automatic devices. In the latter case, the workpieces are fed manually;
  • the third is used in home workshops and in industries where the accuracy of the cut does not really matter. When compared with the first two classes, the performance of saws in this category is 1.5-2 times less;
  • the fourth. household models of saws for metal, including tabletop modifications. Compared to industrial models, the resource of household saws is much lower. Therefore, the equipment of the fourth class is designed for occasional use in the home workshop.

When working on metal, tape blades with teeth (universal version) and electric spark blades (in industrial versions) are used.

How to choose the right band tool?

Since band saws are versatile tools that can work not only on metal, but also on other materials, the option to adjust the speed of the saw blade is desirable. This makes it possible not only to perform a work task with high quality, but also does not damage the equipment. Hard metals are cut at a low speed, while softer materials are cut at a high speed. The second parameter that you should pay attention to when buying is design features. The swivel jaws of the band saw tool allow for straight, angular and curved cuts. When buying a band saw, pay attention to the size of the blade teeth: the larger they are, the deeper the cut is obtained.

Materials and tools

Before starting work on the manufacture of a hand-held band saw for metal, it is necessary to prepare the necessary materials and equipment:

  • grinder;
  • screwdriver;
  • grinding device;
  • consumable accessories (electrical tape, glue-moment, fasteners, etc.);
  • hand tools (screwdrivers, screws, knife, scissors).

To assemble a machine from scrap materials, you need to find:

  • wooden panels (will be used under the base and countertop). if chipboard is used, then several layers must be glued to ensure the necessary strength indicators;
  • channel, steel rods (required at the stage of creating the basis for tensioning the rotating axes);
  • rubber (bicycle or tire tubes). will be used to secure the cutting band to the pulleys;
  • belt (useful for rotating discs);
  • waterproof plywood with a thickness of 10 mm (will go for the manufacture of a protective cover);
  • motor and wires (the choice depends on the required power of the device).

Features of the device and use of a band saw for metal

A metal band saw, also known as a band saw, is a stationary tool used in straight and curved cutting of metal parts. Due to the convenience, ease of operation, the equipment has become widespread both in large construction industries and when carrying out repair work at home or in the country. We will understand the peculiarities of working with the instrument, as well as the process of its self-production at home.

Classification of band saws

By design features, band saws are:

  • Cantilever (pendulum) band saw. in its manufacture, a special saw arm is used, which rises and falls due to the rotational action of the hinge. This type is used for sawing stainless steel pipes, pre-packaged profiles, rolled.
  • Single-column. they are based on a horizontal saw frame that descends along a vertical column. In terms of design parameters, it is similar to a radial drilling machine. The main advantage of this type is the ability to cut metal products at an angle.
  • Two-post. also use a horizontal saw frame that moves along 2 vertical columns. The connection to the bed is carried out using a rigid closed loop. The advantage of two-column saws is considered to be high levels of competition severity, the tool can be used for cutting any metal.
  • Gantry machines. consist of a fixed working area and a movable gantry for cutting, on which it is possible to process materials of large dimensions (plates, castings). The advantage of the tool is its compactness: since the portal moves along the linear guides of the desktop, the equipment does not require a lot of free space.
  • Vertical band saw for metal. designed for both straight or curved cutting along the outer and outer contours. Principle of operation: the workpiece is not clamped in a vice, but manually held in the working area.
  • Rotary (angular). allow you to cut metal at different angles to the axis of the part. Their design is based on a pivoting saw frame that rotates around a vertical axis. This allows you to adjust the cutting angle in one motion.

Operation of a hand-held band saw for metal

After the instrument has been manufactured and tested, it is important to follow simple rules for the safe use of the device. This is a guarantee of a long service life of the machine, high quality work, and safety of the saw for you.

Rules for choosing a tape blade

  • When buying a cutting blade, look at the edge: all the teeth should be the same, evenly spaced from each other;
  • Choose a canvas that can be sharpened again;
  • Determine the required type of component depending on the format of work:
  • bimetallic. used when cutting durable materials, characterized by increased strength (the tool will last a long time, the saw is resistant to tears and tension);
  • diamond. designed to work with marble, granite, quartz, stone;
  • carbide. needed for sawing cast iron and titanium, can be used when processing complex workpieces;
  • made of tool steel. a classic blade, suitable for one-time work with wood and metal, is the least expensive.

Advantages and Disadvantages of Using a Band Saw in Repair

The reasons for the widespread use of band saws in small business and private practice are:

  • Low costs for installation of the device: the tool is compact and does not require a special foundation; special training is not required to assemble the machine;
  • the ability to cut parts large in diameter;
  • ease of use;
  • simplicity of design;
  • high productivity, including the ability to adjust the cuts, an even cut of the metal, minimal material loss during sawing, processing accuracy;
  • low heat transfer to the air (there is no sudden temperature jump in the room).

The disadvantages of using a band saw during construction and repair work are:

  • High noise level (work near living quarters is not recommended);
  • significant vibration on manual installations (CNC machines are not available for personal use and are presented only in large industries);
  • large dimensions of the tool: the saw cannot be used in a small room, additional space is required for storing workpieces.

The device and technical parameters of the band saw

The main element of the band saw is the closed-shaped cutting blade. Its width is from 6 mm to 4 cm.

Pilana Metal – bi-metal band saw blades

Types of saw blades:

  • toothed;
  • friction saw;
  • electrospark.

The belt blade consists of teeth made of high strength alloy steel. The tooth pitch (number of teeth per 1 inch) of the blade changes in the following ranges:

  • for instruments with a constant pitch: from 1 to 32;
  • for equipment with variable pitch: from 10/14 to 0.75 / 1.25.

One of the most important characteristics of the device is the setting, which means the amount of inclination of the teeth to the plane of the blade. With this parameter, the required path of the blade and the edge of the tooth is ensured.

There are four types of wiring:

  • Standard. represents the classic combination of teeth (right, left, straight);
  • right-left setting. alternation of teeth turned right and left (used when processing soft metals);
  • wave wiring. a special type of wiring, used for tools that cut out small-diameter workpieces;
  • combined wiring. a type that combines elements, designed for sawing pipes and structures with a variable cross-section.

Other knots of the belt:

  • bed (frame). necessary to give the tool stability and minimize vibration during operation;
  • a work table on which a stop and a ruler are installed;
  • two drive pulleys, the rotational movements of which drive the entire mechanism;
  • motor (from 2kW);
  • device control panel;
  • parts lubrication system;
  • protective case.

The following metals are used in the production of band saws:

  • carbon steel;
  • spring steel;
  • tool alloys;
  • high speed steel;
  • hard alloys.

The tool can be used both for woodworking and for cutting steel.

Step-by-step instructions for making a hand-held band saw for metal

  • Determine the intended purpose of using the machine, the required dimensions of the tool.
  • Download from the Internet or make your own drawing of the device.
  • Prepare your workplace, tools, materials.
  • Make pulleys: you need plywood or chipboard, the recommended diameter is 24-26 cm.
  • Pulleys must be sanded and pasted over with rubber on the inside.
  • Make a vertical axis: you can use a metal channel or durable types of wood.
  • Prepare the base of the base (any stainless steel will do).
  • Insert bushings on both sides of the base, on which you fix the pulleys (item 4). The pulleys must be level and not tilted.
  • If available, install a damper (under the tabletop): it will minimize vibrations and vibrations during machine operation.
  • Fix the motor, ensure its firm connection with the rotating part of the tool (item 5).
  • Assemble the countertop from the existing wooden panels, if desired, cover it with an insulating layer. Place the worktop on a sturdy, stable foot.
  • If in work you need to make straight longitudinal cuts, then you need to install the guides.
  • Install an adjustable lubrication system above the table top: the oil should flow by gravity onto the saw blade (the amount is established experimentally during the operation of the machine).
  • Attach a protective cover to the upper pulley: it is necessary to prevent the saw blade from slipping. The cover should cover the entire engine and electronics to prevent sawdust from getting into the mechanism.
  • If you doubt that the engine will cope with large volumes of work, then it is better to install a residual current device (RCD).
  • Cut off all sharp corners, sand the surface of the tool.
  • Install the band blade, tightening it as much as possible (chain slack is not allowed). The tape should be located strictly parallel to the base so that the canvas does not come off.
  • Carry out a test run of the machine, make a test cut of a thin steel or metal sheet.
