Spindle adapter used in the production of heat-resistant casting sand molds has a pulling head connected to a non-rotating main drive spindle of a stationary machine tool

摘要

Spindle adapter has a pulling head (6) connected to a non-rotating main drive spindle (1) of a stationary machine tool under the action of a locking device (5). The head has a rod-like extension (23) having a drive motor (19) on its free end to rotate the tool. The motor has an outer diameter which is smaller than the circular diameter of the rotating tool.
