1. The physical phenomenon of titanium alloy processing
1. Even if the cutting force of titanium alloy parts is slightly higher than steel, its physical phenomenon is more complicated than steel, so it will face greater difficulties during the production process.
2. The high temperature generated during the cutting process will destroy the surface integrity of titanium alloy parts, resulting in a decrease in geometric accuracy of the parts.
3. The elasticity of titanium alloy may be conducive to the performance of the parts, but the elastic deformation of parts is an important cause of vibration during the cutting process. The cutting pressure causes the elastic components to leave the tool and rebound, so that the friction between the tools and the components is greater than the cutting effect. The friction process will also produce heat, which exacerbates thermal conductivity of titanium alloy components, so there will be more and more sub -products.
Second, titanium alloy parts are easy to deform during processing.
Based on the characteristics of materials, titanium alloy parts are easy to deform during processing, especially some easy -to -deform products, such as thin walls and rings, which are more serious. Because thin -walled titanium alloy materials are not easy to process to expected size accuracy, the tolerance of titanium alloy products cannot be controlled.
Third, titanium alloy parts can shorten the life of the tool faster.
Most titanium alloys have low thermal conductivity, only 1/7 of steel and 1/16 of aluminum. Therefore, during the cutting process of titanium alloy, the heat will not be transmitted quickly to the parts, and it will only gather in the cutting area. Therefore, the temperature rises to more than 1000 degrees, and the tool is easily ruptured.
