摘要

The tool head includes a base plate and a tool shaft coupled to the machine tool drive spindle and an electric motor driven tool position adjustment. The tool head has a base plate (10), rotatable about an axis (12), with a holder (16) for a cutting tool on a transversely moveable carrier (14) whose position is monitored by a sensor (20), a reduction gear (22), an electric adjustment motor (24) and in put drive shaft (28). The geared sliding arms (67,69) are moved by a spur gear (68,70) on the output shaft (72). The reduction gear (22) is a harmonic drive (82,84) from the motor.
