Piston type compressor

A method for machining a groove in a sealing member and the edges of the groove. A tool 24 is formed with a top portion 24 having cutter sections 23A, each defining a cutting edge 23 for machining a groove in a scroll wall of a scroll member, and a tapered part 25 having cutter sections 26A, each defining a cutting edge 26 for bevelling the edges of the groove and the edges of the scroll wall. The groove 9 and edges 11 are simultaneously machined.

Method for machining a scroll member

A method for shaping a scroll member for a scroll compressor, capable of increasing a service life of a cutter tool, while reducing the cost. At the corner between the base plate 2 and a scroll wall, a roundness 3a of a small radius R1 of curvature is first machined along an entire length of the scroll wall in its spiral direction. Then, a roundness 3b of a large radius R2 of curvature is machined only at a spirally inner end of the scroll wall.
