What processes do we have for precision parts processing?

Precision parts processing covers a variety of key processes. NC machining technology is widely used, and NC milling can accurately shape complex shapes with the help of milling machines, such as aircraft wing connectors; CNC turning focuses on the revolving body, and the machining accuracy of automobile crankshaft can reach micron level; NC EDM is used to overcome the high hardness and complex parts, and the mold cavity accuracy is about ± 0.05mm.

Precision grinding process should not be underestimated. Cylindrical grinding creates a high-precision cylindrical surface with a surface roughness of Ra0.8- ra0.1 μ M; The inner hole is refined by internal grinding, and the dimensional accuracy is ± 0.002mm; Surface grinding ensures flatness and controllable error.

Special processing has unique advantages. Laser processing uses high-energy laser beam to cut and punch holes, and electronic chips are cut with micron precision; Electron beam machining is good at making micro structures, and the accuracy of the cooling hole diameter of aerospace blades is very high; Ion beam processing realizes atomic level operation.

The precision grinding and polishing process is completed. The grinding improves the size and finish. The roughness of the optical lens is less than ra0.01 μ M. the polishing gives the mirror effect and makes the parts perfect.
