Abstract
In a scroll machining method, a scroll has a disc-like end plate and a scroll wall extending from a first side surface of the disc-like end plate, and the scroll is driven to rotate around a center axis C of the scroll, and a first cutter machines a side wall surface of the scroll wall while the scroll is rotating. The first cutter is a non-rotary cutter. When the scroll is machined, the scroll rotates around its center axis, and the first cutter does not rotate around its axis, thereby improving the scroll's machining precision and machining efficiency.
Claims21
A method for machining a scroll in a machining process, wherein the scroll comprises a disc-like end plate and a scroll wall extending from a first side surface of the disc-like end plate, and wherein the method comprises:
- machining a side wall surface of the scroll wall by a first cutter when the scroll is driven to rotate around a center axis of the scroll, the first cutter being a non-rotary cutter,
- wherein during at least a part of the machining process, the first cutter moves along a first direction parallel with the center axis while cutting material from the side wall surface of the scroll wall and along a second direction vertical to the first direction and pointing to the center axis while cutting material from the side wall surface of the scroll wall.
