Abstract

PURPOSE: To grind along the surface of a slab with an equal depth while keeping the load of a wheel driving motor at a constant level and remove and scale, by fitting a wheel push controller to a slab grinder.
CONSTITUTION: The load current signal 30 of a wheel driving rotor from a motor driving device 29 of a wheel driving motor 28 is put in a comparator 32 through an ac-dc converter 31. The signal 30 is compared with the wheel motor setting signal 34 and its difference, if any, puts out a work command signal 33 to a proportional solenoid pressure control valve 27 which controls the flow in a branch oil pipe 24. The pressure flow passing through a one-way valve 13 for grinding operation is controlled to adjust the wheel pushing force and equalizes the load current of wheel driving motor with the preset current for the motor.
