: The operation relieving of center drills is realized by the method of the profile plunge grinding. The big variety of profiles and diameters of the center drills makes difficult the utilization of cam-levers automatic machine in The large number production. This is a reason for the designing of a new automatic machine for production of center drills, supped with CMC system, A subject of description in the paper is the system for control. The alder diagram is Include, typically for an automatic machine M-commands, coding and inserting into ROM-memory for programming controller of an automatic machine. 72 hours examinations have been made, after which an automatic machine is working in the regular production of a firm "INSTRUMENT AG'- Gabrowo.
