Vertical drilling machines: specifications and advice on choosing

Vertical drilling machine can perform various work on reaming, as well as deployment. In addition, it is possible to make perfectly smooth holes of different diameters on the parts. In industrial enterprises, with the help of these aggregates, they are engaged in tapping. For this purpose, the various milled parts are best suited. In turn, the spindle allows you to work with steel, as well as cast iron surfaces. In addition, it is possible to cut non-ferrous metal blanks.

Drilling machine assembly

At the top, the vertical drilling machine has a main drive. Under it is a special box. With it, you can change the speed of the device. Support the box with two plunger pumps. The feed system is located above the spindle. Then comes the plate on which the workpiece is mounted. The electric motor of the machine is in a special cabinet. To the right of it there is a cooling system. To control the device provides a lot of buttons, as well as pens.

The cooling system is activated by a separate crane, which is located at the top of the machine. To move the table there is a handle. In this case, the head of the machine will also move. The power button is located on the side of the device. There is also a lever for rotating the spindle. The speeds, in turn, are switched by a separate screw. To cut off the depth of processing, a limb is provided in the mechanism. Among other things, it is necessary to isolate the pump switch. It is located at the bottom of the drilling machine. To control the depth of cutting, use a cam. The automatic reverse of the drive is activated by the lever. A separate lever is provided to operate the feed mechanism. The diagram of the vertical drilling machine is shown below.

How to choose a drilling machine?

First of all, you should determine the functional part of the machine. Generally, manufacturers produce universal models for reaming, drilling, and deployment. The power consumption of the device must be at least 600 W. The tension of the machine is different. Cartridges are installed in the limit from 1 to 16 mm. The cones of the spindle are produced in different classes and are selected separately. Its reach should be at least 170 mm in diameter. Thus the size of a free wheeling should make approximately 80 mm. In general, the spindle is easily adjustable. The minimum distance between it and the table is 510 mm. At the same time, it is possible to remove up to 700 mm.

Tables in machine tools are available in different sizes and depend on the model. On average, its length and width are 300 mm. In this case, the base of the device must be at least 400 by 300 mm. The average diameter of the column is 70 mm. The number of speeds in the mechanism depends on the machine block. Usually there are about 12 transmissions. At the same time, the speed ranges range from 180 to 2500 per minute. Lastly, you should pay attention to the T-shaped groove of the drilling machine. It should not have any defects. The average weight of the device fluctuates around 60 kg. The length of the model should be approximately 900 mm, width - 500 mm, and height - 300 mm. In this case, it is better not to give preference to compact machines. The average price for these units is 300 thousand rubles.

Machines of the trade mark "Proma"

In general, the machines (vertical-drilling) of the company "Prom" had time to prove themselves on the positive side. Separately, one can note a good speed of revolutions.
