Message: | Edgar is from a hydraulic company in Britain and has been engaged in procurement for 2 years. Recently, the supervisor asked him to purchase a hydraulic cartridge flow control valve with a rated pressure of 15~20MPa, a fit clearance of 0.012~0.015mm and a cylindricity of 0.003mm. The supervisor specially emphasized that this was the project the boss was looking at. Edgar saw the parameters of this hydraulic cartridge flow control valve and was a bit stunned. It was difficult for his current hydraulic cartridge flow control valve manufacturers to reach the standard. Although one of the manufacturers promised to be 90% sure, the cylindricity accuracy could not be approved, because the processing of the blind hole of the hydraulic cartridge flow control valve was not sufficient enough. He failed to meet the standard even after 3 adjustments. More than a month has passed, and no progress has been made. Edgar was very worried. |
