In the production of gr5 titanium alloy rods, we often need to perform surface treatment due to the differences in the materials and processes used. As a professional supplier of titanium alloy rods, we have sorted out the following physical polishing methods for you in many years of actual production, which are suitable for surface polishing of titanium rods and titanium products.
1. Fine grinding
That is to use conventional various emery rubber wheels to grind the surface of titanium and titanium-containing alloy castings. The problem that should be paid attention to during grinding is still not to make the casting generate heat, not to cause grinding damage on the surface of the casting, and to make the entire surface smooth and smooth.
2. Barrel grinding method
The so-called barrel grinding method is to put the processed castings, abrasives, water and additives into a barrel grinding tank, and the grinding barrels rotate and vibrate, causing friction between the abrasive mixture and the processed castings, and grinding the surface of the castings smoothly. ,smooth. It is characterized by no dust pollution, low labor intensity, and no heat generation in the conventional grinding process. At present, Japan has commercialized barrel grinders and abrasives for grinding titanium and titanium-containing alloy castings, other metal castings and plastics. The roughness of the surface is also high. Although the grinding efficiency of SA and B series abrasives is not as good as that of PK, the surface smoothness of the ground titanium castings is high. At present, the Fourth Military Medical University has successfully developed a domestic dental barrel grinder.
3. Mechanical polishing method
The method of polishing the surface of titanium and titanium alloys using soft cloth wheels or black brushes of different specifications, dipped in special polishing pastes for titanium and titanium-containing alloys. When polishing titanium castings, it is necessary to completely clear the contamination layer on the surface of the casting and no new grinding and hardening layer, otherwise the ideal polishing effect will not be achieved. High speed and light pressure are still used for polishing. Some people have tried to use green polishing paste to polish titanium and titanium-containing alloy castings, and achieved a relatively ideal polishing effect. Polished titanium and titanium-containing alloy castings cannot be washed with water immediately. The surface oxide film must be completely formed before washing, otherwise the surface will become darkened.
