The precision machining process of the centrifugal pump refers to the processing precision of the centrifugal pump and the smoothness of the surface are higher than the various processing processes of the corresponding processing methods.
Precision machining processes include precision machining (such as diamond boring, precision turning, wide-blade fine grazing, etc.) and high-gloss and high-precision grinding. Precision machining precision is generally 10~0.1μm, tolerance class is above IT5, and surface roughness Ra is below 0.1μm.
High-gloss and high-precision grinding includes precision grinding, ultra-precision grinding and mirror grinding.
High-gloss and high-precision grinding requires high precision and rigidity of the machine. The grinding process uses finely-trimmed grinding wheels to produce multiple contoured micro-cutting edges on each abrasive grain with a small grinding depth. Under proper grinding pressure, the fine chips are cut from the surface of the workpiece plus the sliding of the micro-cutting edge in the micro-cutter state, the extrusion, the smoothing action and the friction polishing of the multiple feed-free grinding stage The function is to obtain a high-gloss surface with high processing precision and good physical and mechanical properties.
In summary, the processing of the centrifugal pump uses a precision machining process to improve the machining accuracy and surface quality of the workpiece.
