Machine tool with replaceable tool holder has sensor on machine tool for detecting coding of tool holder fitted to machine; sensor signal is a control criterion for machine tool drive

摘要

A coding (61,71,81) is provided on the tool holder (6-8) and a sensor (9) on the machine tool (1) for detecting the coding of the tool holder fitted to the machine. The sensor signal is a control criterion for the machine tool drive (2). Control electronics (3) in control the speed of the drive motor to a value associated with the detected tool holder.
