The article presents the following materials: 1) Developed two-circuit automatic process control system on a lathe, designed to perform finishing types of treatments. 2) The developed automatic system provides regulation of two parameters of technological process: constancy of the tool feed and the gap in the hydrostatic guides is independent of changes in cutting forces, which ensures the accuracy of geometric dimensions and the quality of the product surface; 3) since one of the elements determining the high-quality operation of a hydrostatic pair is an information-measuring device-a differential inductive sensor, calculations of its parameters are given, as well as the characteristic of the amplifier to this sensor.
