Abstract

PURPOSE:To heighten working efficiency, by performing thrusting by a force equal to a cutting force in response to its fluctuation. CONSTITUTION:The variable resistors R1-R12 of a control circuit 11 are adjusted to regulate a voltage for a pressure control valve 8 to set oil pressure for a rest in each step of one rotation of a workpiece. To change the step, dogs D1-D4 and limit switches LSW1-LSW4 are combined with each other and relays CR1-CR12 are operated. The steps are sequentially detected synchronously with the rotation of the workpiece to control the rest pressure by the action of the pressure control valve 8 in each step.
