Precautions for precision machining of titanium alloy 'hardware'

Titanium alloy has the characteristics of high strength, low density, mechanical properties, toughness and corrosion resistance, etc., which are used in many industries. However, titanium alloys also have the characteristics of low thermal conductivity and high chemical activity at high temperatures. Cutting and processing are difficult, and the production and processing of precision stamping parts is complicated. In order to ensure the quality of titanium alloy products, the following points need to be paid attention to during the precision processing of titanium alloys: Titanium alloy has a low thermal conductivity coefficient. When processing precision stamping parts, heat accumulates on the local surface of the workpiece. It is easy to cause the tool temperature to be too high and cause 'burning'. Therefore, the quality of the tool is required and the cutting linear speed is low (low speed, low Feed). The tool is preferably a special titanium alloy tool. If not, you can also use a cemented carbide tool. The higher the hardness, the better. It is recommended to be above 55 degrees. 2. Since the hardness of the titanium alloy processing tool is higher, the texture is tighter, and the heat transfer effect is better, so try not to use coated tools. Titanium alloy materials will have an 'affinity' reaction with the titanium in the coating, resulting in 'sticky knife' . 3. Titanium alloy has low density, low hardness, and the material is very cotton, which is easy to 'give the knife'. During rough machining, only 'cutting is not in place' will occur, but 'overcutting' will not occur. In order to avoid 'letting the knife' size is not in place, titanium alloy precision machining and repeated machining, leaving as little margin as possible to improve the efficiency of titanium alloy precision machining. 4. Cooling measures must be taken during precision machining of titanium alloys, and no dry cutting is allowed. Pay more attention to the finishing of small micro cutting. Titanium alloy chips with very small particle size will 'burn' at about 200 degrees Celsius, which will affect the forming quality of precision stamping products. Regarding the precautions for precision machining of titanium alloys, I will stop here today. Titanium alloy is a kind of material that is difficult to process. To ensure the quality of the product, it is necessary to correctly select the tool material according to the characteristics of the titanium alloy, keep the tool sharp, adopt a good cooling process, and strictly follow the relevant processing attention during the processing process. matter.
