OPERATING METHOD FOR WHETSTONE DIAMETER EXPANDING/CONTRACTING MEMBER OF HONING MACHINE, AND HONING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an operating device for a whetstone diameter expanding/contracting member of a honing machine capable of feeding a whetstone member in the radial direction certainly for a certain specified amount.;SOLUTION: The honing machine includes a honing head structured so that a whetstone mounting plate whereto a whetstone is fixed in a whetstone mounting hole formed in the circumferential direction is held movably in the radial direction and a rod 12 having a pushout part in a tapered shape is lowered by a feed motor 48 to move the whetstone in the radial direction. Also the honing machine includes an NC device 71 equipped with an arithmetic operation control part 78 to control integrally the drive of the feed motor 48 etc. The arithmetic operation control part 78 sets the target position of the rod 12 on the basis of the specified feed amount of the whetstone 26, and when the head rises relative to the hole to be processed, moves the rod 12 when the movement target position of the rod 12 shifted (corrected) downward for a portion corresponding to the play (gap) in the vertical direction of the whetstone mounting plate 24 in the whetstone mounting hole is used as the final target position.;COPYRIGHT: (C)2004,JPO
