Titanium and titanium alloy polishing method:

1, fine grinding
Conventional types of emery rubber wheel containing titanium and titanium alloy castings surface grinding. The grinding should pay attention to the problem is still not allow casting thermogenesis, not caused by the grinding of the surface of the casting injury, and the entire surface to be smooth.

2 barrels grinding method
So–called barrel grinding method is to be machined castings, abrasives, water and additives into the barrel polishing groove generating rotation and vibration mill barrel, and make the casting of a mixture of abrasive and are processed to generate a friction between the casting surface polishing smooth and smooth. Characterized dust pollution, low labor intensity, heat production phenomenon does not occur in conventional grinding process. Currently, Japan has been commercialized the barrel grinding machine for sale of titanium and titanium alloy castings containing other metal castings and plastic such as polishing abrasives. After tests confirmed the pk series abrasive grinding efficiency is the highest, but the surface of the rough rate is the highest. SA and B series of abrasive grinding efficiency, while not, such as PK, but the the titanium casting surface smoothness after the polishing was highest. , Fourth Military Medical University successfully developed China’s first dental barrel grinder.

Polished

3, the mechanical polishing method
Soft cloth wheel using different specifications or black brush, dipped in a special polishing paste containing titanium and titanium alloys for titanium and titanium alloy surface polishing method. Polished titanium castings must be completely clear the casting surface contamination layer and no new grinding hardened layer will not be able to achieve the desired polishing effect. Polishing still using the high speed, the manner of the light pressure. The authors have also experimented with green polishing paste containing titanium and titanium alloy castings polishing, the ideal polishing effect. Polished containing titanium and titanium alloy castings can not immediately enter the washing must be fully formed surface oxide film before the washing, otherwise the surface will darken phenomenon.
