Combined correction system for multi spindle automatic lathe - has drive with friction couplings for spindle and tool adjustment

摘要

The correction system corrects the spindle position deviations, compensates cutter wear and has an electric motor driven adjusting arrangement operated by a conventional bridge circuit with manual intervention being possible. The electrical and mechanical actuating elements are coupled by a coupling, for example by a friction coupling (3) accurately and independently of each other and the adjusting spindle (10). The correction displacement is transmitted to the potentiometer (16) by a worm and wheel drive (7, 15), friction coupling and gear drive (5, 16). The correction displacement can be transmitted via a setting sleeve (2) and an intermediate rod (17).
