The composition of the drilling machine with the CNC for sheet metal

The scope of the drilling machine with CNC for processing sheet steel

Portal drilling machines are one of the most popular types of equipment for processing sheet metal. The machines of this design are used in almost any industry.

The portal drilling machine is designed for the mechanical processing of steel structures, towers, bridges, as well as the implementation of various technological operations associated with the drilling of thick.faced rolling and supporting plates.

The main components of this machine are a bed, a portal, a drilling power head, a spindle hydraulic system, a control system, a centralized lubricant system, a cooling system, a chip removal system, an automatic clamping system of processed parts and a quick.combat cartridge.

The bed and portal of this machine is a steel welded structure, which takes place artificial aging to relieve internal stresses, so the machine has minimal deformation with high dynamics and large loads.

In the basic configuration, the machine is equipped with one drilling head. At the request of the customer, the equipment can be equipped with additional drilling heads.

The drilling heads used in the machine are used for standard drilling at the speed of rotation of the spindle up to 560 about./ min.

To cool the drill on the portal drill machine, a coolant supply system is installed.

Each machine is equipped with a collapse system. Bubbed under the work table of the machine and container for shavings.

The machine includes a hydraulic clamping device. Small.sized processed parts can be clamped on a quadrangular desktop, which reduces the period of preparation of production and increases the efficiency of processing.

This series is intended only for drilling a through hole in a metal sheet. And C uses a hydraulic drive along the axis Z , Morse cone 4

Popular models of crown drilling machines

In the company of the Moscow Region, you can buy magnetic drilling machines from the best manufacturers in a wide price range for drilling holes from Max. with a diameter of 25 to 200 mm.

Useful tips

Then some recommendations will be given that will help to achieve proper and highly effective drilling.

Correctly carry out the center of the drill.

Nap the marking hole (do not use the pushing pin for this), place the pushing pin in the recess and turn on the magnet. After that, check the pin position again, as it happens that when the magnet is turned on, the tripod shifts.

Fixing a drilling point for diameters of 12. 15 mm is very important. For large diameters, this is strongly recommended.

Select speed.

The choice of proper speed of rotation is very important. Pay attention to the inadmissibility of work with the excess of the recommended speed. The minimum permissible rotation frequency is approximately 25% smaller than recommended. The carbide drills are more sensitive to excessively low speed, this leads to increased vibration and painting. Drills from high.speed and powder steel fail when exceeding the recommended values ​​by more than 20%.

Use the correct feed.

At the beginning of drilling, reduce the feed twice from the recommended (see.the table below). Remember that excessive pressure on the drill will not lead to an increase in speed. to increase performance, use carbide drilling drills and machines with an increased speed of rotation. If you have to make significant efforts, perhaps the drill is torn or the drilled material is too hard.

Control during drilling

If the machine is not equipped with a chipper, periodically take out the drill and clean it from chips. In this case, you should use a special hook. Drilling light materials is carried out in one appointment.

When drilling holes deeper than 15-20 mm, adhere to the following rules:

• Upon reaching a depth of 15-20 mm, remove the drill from the hole and clean the shavings from it;
• fill the cavity of the hole with grease;
• Drill with a small feed until the chips again appear outside;
• Repeat everything again.

Application of lubricating and coolant fluids (coolant)

During the drilling, it is important to use high-quality lubricating and chirrels. As a rule, liquids are used. co.chezh.

It is allowed to use durablue drills without the use of coolants, the drill resource in this case, compared with the same conditions, but with the use of coolant, is reduced. When drilling holes with a diameter of more than 37 mm, the use of coolants is strongly recommended in any case.

Sufficient cooling is especially important when drilling hard.to.process and heat.resistant materials, stainless steel. In these cases, organize the feed from the inside and outside.

If Kern is stuck inside the drill

The reason for the staining of the core inside the drill is usually:

• too much pressure in the process of operation;
• absence or insufficient cooling;
• incorrectly selected rotation speed:
• drill wear;
• explosion wear of the explosor or curvature of the pushing pin.

Very often Kern itself falls out after cooling. In any case, do not make significant efforts to extract it:

• First, try to take it out, shaking your hand slightly (put on the mittens so as not to cut);
• secondly, using an awl or screwdriver, evenly from all sides, slightly tapping with a hammer (see. picture).
• You can also remove the drill of the Islykhkhkhkhki with a pin on the hard surface.

Drilling materials with non.parallel planes

The main danger is the output of the drill, so reduce the feed before the completion of the drilling. It is also recommended to use drills from high.speed or powder steel.

When using machines with automatic supply. switch them to manually.

Drilling modes

When drilling, efficiency, as well as labor productivity in most cases, is directly dependent on the amount of the feed (t.e. the value of the deepening for one complete revolution of the drill into the processing of the part) and the speed of rotation of the drill. When choosing a cutting speed, it is necessary to take into account the diameter of the drill, the presence of cooling, the properties of the processed material, the depth of drilling, etc.

Drilling of various types and sizes are used on drilling machines. Tools used as auxiliary are required to ensure the consolidation of the working tool. The conductor used in mass and serial production and providing high.precision processing without applying holes in various blanks are of no small importance. Universal.type devices include universal and straight squares, machine vice, clamping strips.

The introduction of deep holes into individual cycles

Unfortunately, standard drilling cycles often have restrictions when it comes to drilling very deep holes. It is often necessary to have an individual drilling cycle of deep holes.

How the individual cycle differs from the usual standard drilling cycle?

Firstly, it is a deepening strategy. It is important to be able to start with a small step and move on to larger ones as the hole becomes deeper. Fulfillment of a complete exit before the hole becomes deep. this is a useless movement. Ideally, you should go down, to a couple of diameters or so, and then start “bite”. The velocity frequency should increase, the deeper the hole is drilled. The nature of the movement should also change depending on the depth of the hole. We start with a small short step. exactly such as to break the chips. But as we are getting deeper, we need longer and lengthy bends, since we need not only to break the chips, but also to facilitate its extraction. Finally, we want a spiral drill to not completely out of the hole, so that the chips do not wash back into the hole.

Secondly, our feed and speed. As the hole becomes deeper, we get an advantage by reducing the feed rate and spindle rotation frequency. There is no need to do this until the hole reaches the threshold depth, but when we are at this depth, it helps a lot.

Finally, while we are programming an individual cycle, we want to decide whether to use fast speed or supply speeds for the clutch and discharge from the hole. This is the reverse movement that does not cut anything, and we have the potential for saving time compared to constant drilling cycles that support all movements at the speed of feed.

Using a special G-code for the implementation of all these considerations, we spend as little time as possible on deepening, guaranteeing that when things are difficult, we do enough for our tool to remain whole. Although standard cycles differ from the controller to the controller, very few of them offer flexibility to manage all these variables.

Drilling holes in metal: any diameters and depths

Drilling holes in metal is one of the types of mechanical processing in which a special tool is used: a rotating drill. Metal processing with drilling helps to get holes of different diameters and depth. They can vary in form. to be accurate or multifaceted. Differents of drilling include zenketing, celebrating, marking, melting and cutting.

Metal drilling services have always been in high demand. Firstly, because the cost of drilling holes in the metal is very democratic. But mainly due to the fact that it is such an operation as drilling and, in particular, deep drilling of metal, helps to solve a number of technological problems. You can make holes for cutting threads, for future fasteners, for laying the cable. Drilling of large diameter metal is often used in the installation of volumetric metal structures, when it is required to drill a hole in the overall cherry, corner, beam or henchman to strengthen the structure.

Drilling holes in the metal, the rate on which depends on the complexity of the work, is heterogeneous and by the type of drill. Carbon and low alloyed are used to process soft metal. For example, they are drunk with copper or aluminum sheet metal. Drills made of high.speed steels with heat resistance within 650 ° are indispensable for work on blanks in an unnecessary state.

Solid alloys drills are suitable for drilling color metabolism and non.cramped steel at high speed. Their heat resistance has a higher indicator. up to 950 °. With the help of them, a metal is drilled, the price of which will be slightly higher, but such drills provide more opportunities. Drillers equipped with a borazon, you can process hardened steel and cast iron. Drilling solid metals is performed by a diamond tool.

Shallow and deep drilling holes in the metal can be carried out on machines of various types. Specialized machines that perform large holes in the metal can be horizontally and vertically drilling.

Drowning work as one of the auxiliary operations is possible for horizontally and vertically milling, boring, as well as for some varieties of turning machines. For such processing as drilling holes in metal, the price of the issue will depend on the complexity of the operation. Indeed, today, along with simple drilling, there is a very specific. for example, deep drilling of metal, five or more times higher than the diameter of the hole. Its cost will be higher than for standard orders.
