HIGH-SPEED ROTARY GYRO PROCESSING METHOD OF DISK WORKPIECE AND HIGH-SPEED ROTARY GYRO PROCESSING DEVICE OF THE DISK WORK

摘要

PROBLEM TO BE SOLVED: To provide a high-speed rotary gyro processing method of a disk workpiece and a high-speed rotary gyro processing device of the disk workpiece, performing both high-speed rotary gyro processing and double-sided simultaneous processing for bringing about the attitude control effect of a gyro mechanism to the disk workpiece itself by rotating the disk workpiece at a high speed.;SOLUTION: This high speed rotary gyro processing method is provided for processing by generating restoring force -P to be uniformized in processing pressure P, by rotating the thin disk workpiece 1 at a high speed by being rotatingly driven by rotary main shafts 5 and 6 by an angular momentum calculation expression based on the moment of inertia I of the thin disk workpiece × angular velocity ω of the thin disk workpiece, for negating a side surface deflection quantity by the processing pressure P in the side surface direction of the thin disk workpiece from this processing part, when processing the outer periphery and side surfaces 1A and 1B of the thin disk workpiece by the processing part 17, by fixing a central hole 1C of the thin disk workpiece 1 to the rotary main shafts (mandrels) 5 and 6.;COPYRIGHT: (C)2011,JPO&INPIT
