Problems solved by technology

This is a job that is highly dependent on the technical level and experience of the processor. At the same time, there is instability in the quality of polishing. Some special workpieces are difficult to meet the technical requirements, and the pass rate is low, which cannot meet the needs of mass production.

Embodiment Construction

[0013] refer to figure 1 , the main technical scheme of the present invention illustrates: adopt a grinding disc 1 of uniform jet, close to the surface of the workpiece 3 rotating on the chassis 4, the grinding disc and the workpiece are immersed in the polishing solution 5 containing certain abrasives, the grinding disc 1 rotates in the opposite direction of the workpiece, It can also not be rotated. During the polishing process, there is a naturally formed gap between the air jet surface of the grinding disc 1 and the processing surface of the workpiece 3, and a layer of gas-liquid film 2 is naturally formed in the gap, so that the grinding disc floats on the workpiece and maintains soft contact. , the abrasive in the gas-liquid film sandwiched between the grinding disc and the workpiece performs uniform and flexible friction polishing on the workpiece, and the processing of the workpiece is determined according to the polishing time.

Abstract

The invention discloses a method of air-floating mechanical polishing, mainly adaptable on fine grinding and super-smooth surface processing of metal parts, optical glass, germanium crystal, monocrystalline silicon wafer, gemstone, quartz crystal, etc. The method is technically characterized in that a millstone with even air-jet, which is close to the surface of a rotating workpiece on the chassis, together with the workpiece is immersed in polishing solution with certain abrasive inside; the millstone can rotate in the opposite direction to the workpiece, or can stay still; in the polishing process, a layer of air-liquid membrane is naturally formed between the surfaces of the millstone and the workpiece; while the abrasive in the air-liquid membrane flexibly and evenly polish the workpiece. The invention is proved by practical application that the method fundamentally improves and stabilizes the quality of super-smooth surface mechanical polishing of the workpiece, greatly increases the procedure qualification rate and overcomes the shortcoming of the original polishing process that the operators are required to have high technical capability and rich experience.

Description

1. Technical field [0001] The invention relates to a mechanical polishing method, which is mainly suitable for fine grinding and ultra-smooth surface processing of metal parts, optical glass, germanium crystals, single crystal silicon wafers, gemstones, quartz crystals and the like. 2. Background technology [0002] In the prior art, for the processing of some precision workpieces, the final surface quality is determined by polishing, so polishing is a very important process in the processing of some precision workpieces. Usually, the polishing of high-quality smooth surfaces uses elastic materials such as sand-pressing plates, asphalt or fibers as grinding discs, and is processed with polishing liquid to meet technical requirements. This is a job that is highly dependent on the technical level and experience of the processor. At the same time, there is instability in the quality of polishing. Some special workpieces are difficult to meet the technical requirements, and the ...
