HONING MACHINE
Document Type and Number:
Japanese Patent JP2017127925
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To more accurately process an inner peripheral surface of a cylindrical part by more appropriately performing an extended control for a radius of rotation of a grind stone in a honing machine.SOLUTION: According to this honing machine, a surface pressure added onto a polishing surface of a grind stone 14 is measured by a first load cell 34A located on a reciprocal operation part 18. On the other hand, the reciprocal operation part 18 is provided with a second load cell 34B, and a load added onto the first load cell 34A itself is measured by the second load cell. In control means 52 for controlling operation of an extended operative mechanism, a differential value between measured values of the first load cell 34A and the second load cell 34B is calculated, whereby a correction value, in which a noise (inertial force) due to reciprocal operation of the first load cell 34A is eliminated from a measured value of the first load cell 34A, is determined. The control means 52 determines on the basis of this correction value, that is, the differential value whether or not the surface pressure added onto the polishing surface of the grind stone 14 falls in a range of a control value, and controls operation of the extended operative mechanism on the basis of the determination result.SELECTED DRAWING: Figure 1
