摘要： PURPOSE:To enable the concurrent machining of both internal groove sides to high precision by connecting a machining tool with a holder containing an internal groove guide, a cutter of uneven thickness and a path broach for a machining groove, to the tip of a vibratory horn so that the cutter will be located on the loop of a vibration wave. CONSTITUTION:When a supersonic vibratory broach has been turned 'ON', a supersonic vibrator 3A begins to work and give a vertical vibration, causing the vibration of the cutter 13 of a broach 12 as a loop, feeding a supersonic vibratory broach downward on a hydraulic cylinder and finishing both sides of a vane groove 21 on the cutter 13 of the broach 12. Then, after the cutter 13 has been through downward from the vane groove 21, broach feed by the hydraulic cylinder stops and the supersonic vibrator 3A comes to a rest. And a fixing jig 23 for a workpiece advances orthogonally with a machining direction, aided by the feeding device for said jig 23, and the broach 12 comes off the vane groove 21, moves upward by the help of the hydraulic cylinder and comes off a rotary compression cylinder 20 for finally returning to the original position. In this way, both sides of the cylinder 20 having small rigidity in a groove breadth direction can be machined to high precision.
