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.

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.
