ABSTRACT:
An electrically actuated tailstock for machine tools, program-controllable both manually and automatically, the movements of which are effected in sequence, producing initially a rapid approach, then a slow thrust movement until the pre-determined pressure load is achieved and, finally, the stopping of the movement with the simultaneous actuation of an electro-magnetic brake for the maintenance of the pressure load during the entire period of operation. The return movement is rapid and can be limited. The thrust load on the axis of the tailstock center is transmitted by resilient means, and is made visible to the operator in the desired value.
