The lathe is a machining tool that processes a rotating workpiece by a cutting tool and can process an outer diameter or an inner diameter of an annular object. The machine tool is the first to be developed.

In recent years, it has been developed as an automated CNC lathe, reducing manpower consumption to a minimum and automatically reaching the stage of machining with the programmed dimensions.

The process of machining a shaft or a pin with such an automatic CNC lathe is performed by precisely machining an outer diameter surface of a continuously supplied bar material by a cutting tool and then cutting the cutter by a cutting bite to a predetermined dimension (hereinafter, The terminology of the pin will be unified on the axis.)

In this case, in the cutting process by the cutting bite, a cutting error occurs in the length before cutting and the sum of both sides after cutting. However, although it is attempted to produce accurate dimensions considering the fact, all the lengths of the axis are not manufactured with the same dimensions, have.

Therefore, it is preferable to separate the one having the tolerance of the tolerance and the one having the tolerance out of the allowable range so as to reduce the defective rate of the product manufactured using the shaft and shaft.
