WORKING METHOD OF WORK

摘要

PROBLEM TO BE SOLVED: To provide a working method of a work capable of securing sufficient squareness and flatness of the work by carrying out working to internally grind a boss inside diametrical part of the rotating work by a boring cutter to be rotationally driven and working to surface-grind an end surface of the rotating work by a fly cutter to be rotationally driven in the same process by one catching clamp (a state not to reclamp a work). SOLUTION: In a working method of a work capable of machining the work 1 provided with a boss inside diametrical part 2 and an end surface 4, working to internally grind the boss inside diametrical part of the rotating work 1 by a boring cutter 15 to be rotationally driven and working to surface-grind the end surface 4 of the rotating work 4 by a fly cutter 21 to be rotationally driven in a state where the work 1 is clamped by a single chuck 11 are carried out in the same process by one chucking clamp.
