1Overview of CNC Double End Grinding Machine for Grinding Air Conditioning Compressor Cylinder:
The machining requirements for parts in the air conditioning compressor industry are very high, as the machining accuracy of air conditioning compressor components directly affects the performance of the air conditioning compressor. At present, the air conditioning compressor industry is using Japan's Guangyang(KOYO)The double end grinding machine is used for processing, but the price of imported grinding machines can easily reach millions, which makes it difficult for domestic enterprises to afford. In response to the monopoly of imported machine tools in China, Haimer has introduced advanced foreign technology and independently developed CNC double end grinding machines. The main functional components such as electric spindles are imported from Japan and Germany, ensuring that the machining accuracy can be comparable to imported machine tools, and the machining accuracy can reach0.001-0.002mmIn terms of price, it is only for imported machine tools60%Highly favored by domestic large and medium-sized enterprises.

3、 Case study of CNC double end grinding machine for grinding air conditioning compressor cylinder:
A certain air conditioning compressor component enterprise in the south needs to carry out cylinder double end face grinding processing, but currently domestic machine tools cannot meet its machining accuracy requirements, and imported machine tool prices are too high. They have approached Shenyang Haimer to solve their machining accuracy problem. Shenyang Haimer analyzed the machining requirements of the workpiece and decided to recommend using a CNC double end grinder for grinding air conditioning compressor cylinders, and provided free trial grinding. The test grinding results are as follows:
