CNC Machining Materials
CNC Machining Cases
A qualified hydraulic pump swash plate must meet specifications for surface hardness and compound layer thickness, hole diameter/hole spacing/verticality, and surface roughness requirements. We conduct inspections during the heat treatment and machining processes to ensure the workpiece achieves the required precision. Especially for surface roughness requirements, we integrate the lapping techniques to achieve a smooth surface with an Ra of 0.2µm for cast iron parts and obtained invention patent of it.
The exhaust gas manifold is used in commercial vehicles or heavy machinery and is characterized by high temperatures. Therefore, there are specific requirements for material and hardness. Inspections will be conducted during the incoming material inspection and machining processes to ensure the workpiece achieves the required precision, with a surface roughness (Ra) of less than 1.6µm and dimensional and shape tolerances of less than 15µm. Recommended materials include high-silicon molybdenum ductile iron or gravity casting aluminum alloy, which can meet the high-temperature resistance characteristics required for exhaust gas recirculation manifolds.
CNC machining is the process of removing excess material using machine tools. The most common CNC machining methods are turning and milling, which involve cutting based on the shape of the workpiece and can be divided into:
- Cylindrical - Turning with rotating workpieces
- Prismatic - Milling with rotating tools
Turning and milling processes can further be subdivided into surface processing, groove processing, hole processing, and contour processing, depending on the shape of the workpiece. The conditions affecting turning and milling processes include rotational speed, cutting depth, and feed rate. These factors require the experience of the technicians to make the most appropriate machining arrangements. CNC machining is the core business of WKPT, where we integrate both in-house and external resources to provide you with the most suitable metal parts machining and shaping services.
