[0002] From a performance perspective, surface accuracy affects the uniformity of the hydraulic pump flow and the smoothness of the blade movement. Failure to meet the requirements will lead to insufficient oil suction, oil leakage, vibration and noise, reduced volumetric efficiency and accelerated wear. In terms of quality control, processing problems can be discovered to ensure the consistency of mass-produced blades. In terms of safety and reliability, in key hydraulic systems, it can ensure that the hydraulic pump can work stably in harsh environments and ensure safe and reliable operation of the equipment.
