Spindle for workpieces used in magnetic shoe type cylindrical grinders and magnetic shoe type cylindrical grinders

摘要

A spindle (12) for rotating the work piece (21) and a holding device (18) for holding the work piece (21), and the work piece (21) is attached to the holding device (18). In order to change the axial distance between the holding device (18) having the holding shoe formed as the magnetic shoe (46) and the holding device (18) with respect to the spindle (12), the spindle (12) A spindle (10) for a workpiece used in a magnetic shoe-type cylindrical grinder equipped with a hydraulic core stroke device (28) connected to a holding device (18) is proposed. The holding device (18), which can be displaced in the axial direction by the hydraulic core stroke device (28), enables the automated supply of the workpiece (21) at a lower cost and the workpiece (21). Since the accuracy at the time of finish processing can be improved, inexpensive grinding of the ring-shaped workpiece (21) becomes possible with high accuracy.
