Materials such as titanium alloys, nickel-based alloys, and stainless steel are extremely difficult to cut due to their unique physical and chemical properties. In actual machining, the high hardness, high strength, and heat resistance of these materials pose a huge challenge to cutting tools. Especially when using end mills for machining, due to the high temperature and strong friction generated during the cutting process, the tool is prone to wear, chipping, or thermal deformation.
Processing Titanium Alloy Materials
Titanium alloys are widely used in aerospace, medical and automotive industries due to their advantages such as lightweight, high strength, corrosion resistance, and high-temperature resistance.
Typical Application Fields of Titanium Alloy Materials
- Titanium alloys are used to make key structural parts of aircraft and spacecraft, such as fuselage frames, landing gear, and engine components. Their high strength and low-density help reduce weight and improve fuel efficiency.
- Titanium alloys are often used to make artificial joints, bone plates, and dental implants due to their good biocompatibility, which significantly improves the performance of medical devices and the quality of life of patients.
- Titanium alloys are used to make exhaust systems, suspension components, and engine valves for high-performance vehicles, improving the vehicle’s overall performance and fuel economy by reducing weight and increasing strength.
Difficulties in Processing Titanium Alloy Materials
- Poor thermal conductivity. The thermal conductivity of titanium alloy is poor, and the heat generated during the cutting process is difficult to quickly transfer to the outside of the workpiece, causing the temperature of the processing area to rise rapidly.
- High strength at high temperatures. Under high-temperature conditions, titanium alloys still maintain high strength, which causes the cutting process to exert a greater load on the end mill tool, resulting in increased tool wear.
- Easy to deform. Due to the high thermal expansion coefficient, the heat generated during processing will cause the workpiece to deform and affect the processing accuracy.
- Cutting tool wear. Titanium alloy has strong chemical activity and easily reacts with the tool during cutting, causing tool wear and adhesion, and aggravating tool loss.
Processing Methods of Titanium Alloy Materials
Choose high-hardness milling cutter tool materials. Carbide milling cutters have high hardness and wear resistance and are suitable for processing titanium alloys. However, the problem of increased wear may still occur at high temperatures, so special attention needs to be paid to the control of cooling and cutting parameters. Ceramic cutting tools have extremely high hardness and high-temperature resistance, but are relatively brittle and are suitable for high-speed cutting and finishing. They can significantly reduce tool wear and improve processing efficiency.
Use low cutting speeds. Due to the poor thermal conductivity of titanium alloys, high cutting speeds will cause the temperature of the cutting zone to rise rapidly, aggravating tool wear. Therefore, using low cutting speed can reduce cutting temperature and extend tool life.
Increase cutting force. In order to overcome the resistance of the high strength of titanium alloy to the end mill tool, it is usually necessary to increase the cutting force. This can be achieved by appropriately increasing the feed rate and cutting depth, which can improve cutting efficiency.
Make full use of coolant. Coolant is crucial in titanium machining. Coolant can not only reduce the temperature of the cutting zone and prevent overheating and wear of the cutting tool, but also lubricate and reduce friction and adhesion between the tool and the workpiece. It is recommended to use high-efficiency coolant and ensure that the coolant can fully cover the cutting area to ensure the cooling effect.
