The precision of modern precision machining and its surface finish are higher than traditional processing methods.Read about what the precision service and etc.Precision machining processes include precision miiling and cutting (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-precision grinding also requires high precision and rigidity of the machine. The grinding process uses a finely-trimmed grinding wheel 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 pressing and smoothing action and the friction polishing effect of the multiple feed-free grinding stage. In order to obtain a high-gloss surface with high processing precision and good physical and mechanical properties. In summary, the precision machining process can improve the machining accuracy and surface quality of the workpiece.

At present, the application of precision and ultra-precision technology in China is no longer limited to a few sectors such as defense defense and aerospace. It has expanded to many areas of the national economy, and its application scale has also increased significantly. Computers, modern communications, film and television communications and other industries now require sophisticated, ultra-precision processing equipment as a supporting condition for their rapid development. Precision and ultra-precision machining of computer disks, video recorder heads, multi-face prisms for laser printers, photoconductors for copiers, etc., are all efficient and high-volume automated production methods.
