The attention of the turning factory for processing titanium alloy parts is as follows:

1. Due to the small elasticity of titanium alloy, CNC machining factories will pay attention to the clamping deformation and force deformation of the turning workpiece during the machining process to ensure the machining accuracy of the turning workpiece; when installing the workpiece, the clamping force should not be too large, as it is necessary When adding auxiliary support.

2. If a cutting fluid containing chlorine is used, hydrogen will be decomposed and released at high temperatures during the cutting process, and hydrogen will be absorbed by titanium and cause hydrogen embrittlement. It may also cause high temperature stress corrosion cracking of titanium alloys.

3. The chloride in the cutting fluid may also decompose or volatilize toxic gases during use. Therefore, the CNC machining factory should take safety protection measures when using it, otherwise it should not be used; after cutting, the parts should be cleaned with a chlorine-free cleaning agent in time to remove residual chlorine.

4. Professional CNC machining factories know that when processing titanium alloy parts, it is forbidden to use lead or zinc-based alloys to make tools and fixtures that contact titanium alloys, as well as copper, tin, cadmium and their alloys.

5. All tools, fixtures or other equipment in contact with the titanium alloy must be clean; the cleaned titanium alloy parts must be protected from grease or fingerprints, otherwise it may cause salt (sodium chloride) stress corrosion in the future.

6. Under normal processing conditions in the CNC machining factory, there is no danger of fire when cutting titanium alloys. Only in micro-cutting, the small pieces cut off will ignite and burn. In order to avoid fire, in addition to pouring a large amount of cutting fluid, it is also necessary to prevent the accumulation of chips on the machine tool. The tool should be replaced immediately after it becomes blunt, otherwise the cutting speed should be reduced, and the feed speed should be increased to increase the chip thickness.

In the event of a fire, fire extinguishing equipment such as talcum powder, limestone powder, and dry sand should be used to extinguish the fire. It is strictly forbidden to use carbon tetrachloride and carbon dioxide fire extinguishers, and watering is prohibited, because water will accelerate the combustion and even cause hydrogen explosion.

The above are the points that VMT CNC machining factories will pay attention to when CNC mahcining turning titanium alloy parts.
