Talk about the treatment method of surface grinding and polishing of titanium tube
1. Mechanical grinding: Titanium tube has the characteristics of high chemical reactivity, low thermal conductivity, high viscosity, low mechanical grinding ratio, and easy reaction of abrasive tools. Ordinary abrasives are not suitable for grinding and polishing titanium. You can use very hard abrasives with good thermal conductivity, such as diamond, cubic boron nitride, etc., and the polishing line speed is generally 900-1 800m/min, otherwise the surface of titanium is prone to grinding burnout and micro-cracks.
2. Chemical polishing: Chemical polishing is to meet the purpose of leveling and polishing through the redox reaction of metal in chemical medium. Its advantages are chemical polishing and metal hardness, polishing area
Regardless of the shape of the structure. The parts in contact with the polishing liquid are polished without special and complicated equipment. The operation is simple, the more suitable for polishing the titanium tube base. However, the process parameters of chemical polishing are not well controlled. It is required to have a good polishing effect on the denture without affecting the accuracy of the denture.
