Patent number: 10328544Abstract: 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.Type: GrantFiled: August 15, 2016Date of Patent: June 25, 2019Assignee: Danfoss (Tianjin) Ltd.Inventors: Yusong Sun, Mickael Bron, Chengshui Huang, Xishuang Zhang
