(6), each face of corase grinding rolling piston circle material；
(7), the fine grinding each face of (finishing) rolling piston circle material is required to regulation is reached.
As stated above, so that it may produce qualified rotary compressor for refrigerant rolling piston.
Compared with prior art, the advantage of the invention is that：
1st, the carburizing steel source of goods is more sufficient, and price is low, and cost saves.
2nd, since carburizing steel has a good processability, piece surface can obtain low roughness, during operating frictional resistance it is small,
Low energy consumption.
3rd, rolling piston is processed using steel pipe form, and endoporus and outer circle all only need a small amount of turning peeling, then there are a small amount of
Grinding allowance, i.e. thermally processable after the cutting of steel pipe materials in the tube, machining workload can reduce more than 50%, steel utilization ratio
Up to more than 90%, therefore reduce manufacture cost.
4th, its rolling piston materials of the manufacturing method of the present invention do not use cast iron, and use common carburizing steel, eliminate
Casting method avoids the pollution and highly energy-consuming generated to environment, is a kind of good method of energy-saving and environmental protection.
