Talk About The Surface Grinding And Polishing Of Titanium Coils And Tubes

1, mechanical grinding: titanium coiler, titanium tube has a high chemical reactivity, low thermal conductivity, high viscosity, low mechanical grinding ratio, abrasives are easy to react and so on. Ordinary abrasives are not suitable for titanium grinding and polishing. Can use good thermal conductivity of very hard abrasives, such as diamond, cubic boron nitride, etc., polishing line speed is generally 900-180Om/min, otherwise the surface of titanium is prone to grinding burnout and microcracks.

2, chemical polishing: chemical polishing is through the metal in the chemical medium of redox reaction to meet the purpose of leveling and polishing. The advantage is that chemical polishing and metal hardness, polishing area and structure shape has nothing to do. The parts in contact with the polishing solution are polished, without specific complex equipment. Operation is simple, the more suitable for titanium coils, titanium tube base bracket polishing. However, the process parameters of chemical polishing are not well controlled. It is required to have good polishing effect on denture without affecting the precision of denture.
