Internal bore polishing is typically done through electrochemical polishing, but for other materials, small holes are usually polished mechanically. Internal bore polishing is challenging, as is inspection, and it consumes a significant amount of labor time. Some internal bores are machined using electrical discharge machining, which offers high precision and good surface finish, but it is time-consuming. Effective methods can resolve various difficulties in internal bore deburring and mirror polishing.

By utilizing mechanical, chemical, or electrochemical processes, this method reduces the surface roughness of workpieces to achieve a smooth, shiny finish. Suitable for polishing and deburring operations on flat surfaces of materials such as stainless steel screws, hard plastics, and mobile phone bracket shells. Complementary products include polishing compounds and polishing needles.

The technique for internal hole polishing usually employs electrochemical polishing, but for other materials, small holes are often polished mechanically. Internal hole polishing is challenging, as is inspection, and it consumes a significant amount of labor time. There is a technique that uses electrical discharge machining for internal holes, which offers high precision and good surface finish, though it is time-consuming. The internal hole polishing technique boasts clear advantages such as stability, strong environmental adaptability, and a long service life.
