(1) Fine grinding
That is, using conventional all types of emery wheel rubber titanium and titanium alloy casting surface grinding. Grinding should pay attention to the problem is still not to make the casting heat, cannot cause the grinding surface of the casting injury, and make the entire surface smooth and flat.
(2) barrel grinding method
The so-called barrel grinding method is to be processed Castings, grinding materials, water and additives into the barrel grinding tank, grinding barrel rotation and vibration, so that the abrasive mixture and the castings are processed friction, the casting surface smooth,smooth. It is marked by no dust pollution, low labor intensity, does not occur during the conventional grinding process of heat production. At present, there is commercially available barrel mills in Japan and is used for grinding abrasives for titanium and titanium alloy castings, other metal castings and plastic.
(3) mechanical polishing method
Use different specifications of the silky cloth wheel or black hair brush, dipped in titanium and titanium alloy polishing paste for titanium and titanium alloy surface polishing method. In the polishing of titanium castings, it is necessary to fully understand the surface of the castings and no extra layer of polish hardened layer will not be able to achieve the desired polishing effect. When polishing is still using high speed, light pressure approaches. The authors have further tested the use of green polishing paste titanium and titanium alloy castings for polishing, and achieved a more ideal polishing effect. After polishing titanium and titanium alloy castings cannot be immediately washed into the water, must be completely formed after the surface oxide film was washed, or its surface will have the phenomenon of darkening.
