Abstract

PURPOSE:To efficiently remove a welded film of iron fiber, adhering to the surface of a grinder, through the peeling method, by injecting a water jet at specific speed and pressure toward a grinding rotary direction of the grinder. CONSTITUTION:A centerless grinder comprises a main grinding stone A and auxiliary grinding stone B, and a work C is supported by a supporting plate 1 intermediately between the stones A, B, and ground while being rotated counter clockwise. High pressure water is injected at speed not lower than 100m/sec and pressure (about 50kg/cm<2>) onto the stones A, B from a pipe 5 through nozzles 6 in accordance with a rotary state of the stone. The nozzle 6 injects the pressure water to the surface skin of the stone in a direction of peeling off a fiber state object of ground molten iron, and a cutting chip is always removed, then ideal grinding work can be performed.
