FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, NC machine tool clamps. Proposed device comprises open body, cyclone communicated with vacuum pump consisting of step motor, rod and wheel with cam, current generator consisting of resistor, operating amplifier, potentiometer and bipolar transistor, filtration element to allow suspension flow from body into vacuum pump air chamber, and microcontroller. Said body represents a nonconducting element. Microcontroller first output is connected to cyclone while its second output is connected to potentiometer. Its third output is connected to step motor.
EFFECT: ruled out fluidity of suspension and deformation of part surface in clamping.
