Groove processing apparatus and groove processing method

摘要

The holder member 4 is rotatably supported at the tip portion 2 a of the sliding member 2 placed on the guide face 1 a of the guide member 1 arranged fixedly inside the cylinder C. The holder member 4 is inclined when the tip portion 3 a of the profiling member 3 is inserted between the holder member 4 and the sliding member 2. Then the tapered end of the processing roller 6 is pushed into the inner peripheral surface of the cylinder where the sliding member 2 and the profiling member 3 move together in the axial direction of the cylinder, thereby to form a linear groove on the inner peripheral surface of the cylinder C.
