Examples of machining and polishing of hydraulic pumps

Realizing the mechanization of the fitting work! Grinding processing of hydraulic pumps.

Utilizing the experience and knowledge gained from years of developing wrapping techniques, we have developed the grinding device ED-380ISR "Tetra," which mechanizes the fitting process to polish the mating surfaces of the cylinder block and valve plate, the heart of the swash plate axial piston pump. Among these, we would like to introduce a case that achieved a high contact ratio. [Grinding Results] ■ Surface roughness < 0.1μm ■ 95% + Contact Ratio * The single-sided lap machine is suitable for processing seal surfaces, swash plates, and piston shoe flat surfaces. * For more details, please refer to the PDF document or feel free to contact us.
