3、 Case Study of Internal Grinding Machine for Air Conditioning Compressor:
A manufacturer of air conditioning compressor piston parts in Shanghai needs to perform internal cylindrical grinding on the air conditioning compressor piston, with high precision and cylindricity requirements0.0025mmConcentricity requirement0.004mmThe surface smoothness requirement is metRa0.2MmAt present, domestic machine tools cannot meet the precision requirements of the customer, so we consulted with Haimer, and Haimer conducted a workpiece trial grinding for them.
