PURPOSE:To prevent undulation on a lapped surface by applying lapping compound between contact faces of scrolls and performing lapping by rotating the rotary scroll with compressed air. CONSTITUTION:A fixed scroll 1 has a lap 1a and a surface being lapped 1b, and a rotary scroll 2, has a lap 2a and a surface being lapped 2b. When performing lapping, lapping compound is applied in advance to narrow gaps 6a, 6b between the lap 2a and the surface being lapped 1a and also between the surface being lapped 2b and the lap 1a, and compressed air is introduced from a suction hole of the scroll 1 and forced into the space between two scrolls 1, 2. The pressure of compressed air slightly lifts the scroll 2 off the scroll 1 and rotates the scroll 2. |
