Swash Plate for Hydraulic Pumps

What is a Swash Plate?
A swash plate is commonly used in hydraulic pumps and motors, playing a crucial role in the bidirectional conversion of mechanical power and hydraulic power.

Functions of Swash Plates
In axial piston pumps and motors, the swash plate, as a flat disc-shaped component, can tilt or shift. This tilting motion alters the angle of the piston relative to the axis of rotation, adjusting the flow of hydraulic oil, thereby controlling the speed and direction of the hydraulic system. This functionality allows for precise control of machinery, such as construction equipment, manufacturing machinery, and other industrial applications.

Machining Techniques Required for Swash Plates
1. Heat treatment – stress relief annealing/soft nitriding
2. Machining – turning, milling, boring, drilling, tapping, lapping

Key Characteristics of the Production of Swash Plates
* Surface hardness and compound layer thickness requirements are necessary, and these are specifically inspected during the heat treatment process to ensure compliance.
* Specific requirements for hole diameter, hole spacing, and perpendicularity are met through tooling confirmation, tool lifespan management, and periodic inspections of tool bars in the machining process to achieve the required precision.
* Surface roughness requirements are addressed using mirror lapping surface processing techniques, enabling the cast iron to achieve a smooth surface with Ra of 0.2µm and even obtaining recognition through patent of techniques.
