What are the reasons for tool damage during titanium alloy CNC machining?

Titanium alloy CNC Machining is a complex process that involves multiple considerations and technical requirements. Titanium alloys have the characteristics of high strength, low thermal conductivity, low plasticity, high friction, and high chemical reactivity, which pose great challenges to processing. Therefore, CNC machining of titanium alloys requires the use of high-power, high torque CNC machining machines, as well as specially designed high-efficiency machining tools. The main reasons for tool damage during titanium alloy CNC machining are as follows: 0001. High temperature oxidation: Titanium alloy is prone to chemical reactions with oxygen in the air at high temperatures, forming a high hardness oxide film, which can exacerbate tool wear. 2. High hardness: Titanium alloy has a high hardness, which causes the cutting tool to experience greater cutting force during the cutting process, which can easily lead to tool wear or chipping. 3. Low thermal conductivity: Titanium alloys have poor thermal conductivity, and the cutting heat generated during processing cannot be dissipated in a timely manner, resulting in an increase in temperature in the cutting area and accelerating tool wear. 4. Small elastic modulus: The elastic modulus of titanium alloy is small, and the surface rebound of the workpiece during cutting is large, which can easily cause increased friction between the back cutting surface of the tool and the workpiece surface, leading to tool wear. 5. High chemical activity: Titanium alloys have high chemical activity and are prone to chemical reactions with certain components in cutting fluids, leading to tool corrosion and wear.
