PURPOSE:To position a sizing device at correct position by automatically correcting the measuring position in response to the machining size and instructing the relative position of the shoulder of a workpiece with respect to the raidally extended surface at programming time. CONSTITUTION:The measuring head 58 of a sizing device 43 consists of a rockable member 64 pivotally supported at a shaft 63 at a support 62 connected to a pilot bar 59 and a piston rod 61, upper and lower holders 65 and 66 separably guided from the rockable member 64 to be approached in the same distance to the member 64, measuring elements 67, 68 contacting a work cylinder Wa projected from the holders 65 and 66, a feed mechanism for relatively moving the holders 65 and 66, and a servo motor 70 connected to the feed mechanism. The measuring position of the head 58 is moved to correct the measuring position in response to the machining size of the diameter of the workpiece. |
