Abstract

PURPOSE:To cause cutting relief, by changing the supplied pressure to each section of an opposed static pressure bearing to perform displacement in a necessary direction during backward movement. CONSTITUTION:In a turning step from a position A to another B, fluid supply to a static pressure bearing 51 is effected through a circuit (a). When the cutting edge of a tool 1 has reached the position B, the reaching is detected by a switch S2 to operate a solenoid valve 12 to change the circuit (a) for another (b). As a result, a pressure difference is made between the static pressure bearings 51, 52 to move the cutting edge backward from the position B to another C to perform cutting relief. When the cutting edge has reached a position D, the reaching is detected by a switch S1 to operate the solenoid valve 12 to change the circuit (b) for the other (a). As a result, the cutting edge is moved forth from the position D to the other A by the pressure difference between the static pressure bearing 51, 52 to attain pressure balance.
