ワークの製造方法
Document Type and Number:
Japanese Patent JP6865088
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that a conventional inner diameter processing method is advantageous in a case where a workpiece is in the simple ring shape or cylindrical shape, however, in a case where the outer diameter shape of the workpiece having a through hole has the poor mass balance with respect to the axis of the through hole or axial direction of the through hole, it is difficult to perform highly accurate hole processing due to uneven wear of a processing object surface since the processing object surface of a through hole inner diameter part of the workpiece is brought into contact with a polishing tool polishing the processing object surface with the deviation.SOLUTION: There is provided a manufacturing method of a workpiece in which an assembly 103 can be formed by attaching a balancer 102 to a workpiece 101 having the deviated mass balance, a contact surface of a processing object surface 101g of the assembly 103 and a polishing tool 104 can hold the equal load by moving the gravity center position Z1 of the workpiece 101 to the gravity center position Z2 of the assembly 103 having the good mass balance, as a result, even with the workpiece 101 having the deviated mass balance, highly accurate hole processing can be performed.SELECTED DRAWING: Figure 1
