1. Preparation before processing
Select appropriate tool materials according to the specific composition, hardness and other characteristics of tungsten alloy. For example, diamond tools have high hardness and good wear resistance, which are suitable for processing tungsten alloy. At the same time, according to the processing technology and workpiece shape, select appropriate tool geometric parameters, such as the rake angle and rake angle of the tool, to optimize the cutting force and cutting temperature distribution.
2. Process control
-Select appropriate cutting parameters
Appropriately reduce the cutting speed to reduce tool wear and cutting force, avoid the generation of built-up edge and burrs, and improve the surface quality. A smaller feed rate can make the cutting force between the cutting edge and the workpiece more uniform and reduce the surface roughness. According to the size, shape and machining allowance of the workpiece, the cutting depth should be reasonably allocated. In fine machining, a smaller cutting depth should be used to remove the tool marks left by rough machining and improve the surface finish.
-Use advanced machining technology
High-speed cutting technology can reduce cutting force, reduce cutting temperature, reduce tool wear and workpiece deformation, and improve the quality of machining surface. Or choose electrospark machining, which is mainly used to process some tungsten alloy parts with complex shapes and high precision requirements. It melts and vaporizes metal materials through the high temperature generated by electric spark discharge. There is almost no cutting force during the processing, which can avoid deformation and surface damage of the workpiece caused by cutting force, and obtain better surface quality.
3. Post-processing
After the processing is completed, the surface of tungsten alloy can be further processed by mechanical polishing, chemical polishing, electrolytic polishing and other methods to remove the tiny knife marks and burrs left during the processing and improve the surface finish.
