Abstract (en)
[origin: EP0311896A2] A follower steady rest (10) for grinding machines (5) for the cylindrical grinding of workpieces (34) by means of a grinding wheel (35) which can be fed in radially to the workpiece axis (14) has at least two jaws (21, 31) which can be placed against a surface (41) of the workpiece (14) at two points (6, 7) offset at a circumferential angle, and, furthermore, has drive means (29, 27) for the infeed of the jaws (21, 31) in synchronism with the reduction in the workpiece diameter brought about by the cylindrical grinding. In the process, both jaws (21, 31) are fed in linearly, the directions of the infeed being in opposition and running at an angle to tangents (42, 44) which are placed at the points (6, 7) on the surface (41).
