Vertical drilling machine can perform various reaming and reaming jobs. Additionally, it is possible to make perfectly even holes of different diameters on the parts. At industrial enterprises, with the help of these units, they are engaged in threading. Various milled parts are best suited for this. In turn, the spindle allows you to work with steel as well as cast iron surfaces. Additionally, you can cut blanks from non-ferrous metals.
Drilling machine device
At the top of the vertical drilling machine has a main drive. Under it is a special box. With it, you can change the speed of the device. The box is supported by two plunger pumps. Above the spindle is the feed system. Then comes the plate, on which the part is installed for work. The electric motor of the machine is located in a special cabinet. To the right of it there is a cooling system. To control the devicethere are many buttons as well as knobs.
Cooling of the system is turned on by a separate tap, which is located at the top of the machine. There is a handle to move the table. In this case, the machine head will also move. The power button is located on the side of the device. There is also a lever to rotate 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, the pump switch should be highlighted. It is located at the bottom of the drilling machine. A cam is used to control the cutting depth. The automatic reverse drive is activated by a lever. A separate lever is provided for the operation of the feed mechanism. The layout of the vertical drilling machine is shown below.
How to choose a drilling machine?
First of all, you should decide on the functional part of the machine. As a rule, manufacturers make universal models for countersinking, drilling, and reaming. The power consumption of the device must be at least 600 watts. In this case, the voltage of the machine is different. Cartridges are installed in the range from 1 to 16 mm. Spindle cones are produced in different classes and are selected separately. Its overhang must be at least 170 mm in diameter. In this case, the free play should be approximately 80 mm. In general, the spindle is easily adjustable. The minimum distance between it and the table is on average 510 mm. At the same time, you can move as far as possible up to 700 mm.
There are tables in the machinesdifferent sizes and depending 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 column diameter is 70 mm. The number of speeds in the mechanism depends on the machine block. Usually there are about 12 gears. In this case, the speed ranges range from 180 to 2500 per minute. The last thing you should pay attention to is the T-slot of the drilling machine. It should not have any defects. The average weight of the device fluctuates around 60 kg. In this case, 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.
Proma brand machines
