As a lightweight, high-strength and corrosion-resistant metal material, titanium CNC processing poses significant technical challenges. In order to overcome its high processing difficulty, easy generation of burrs, plastic deformation and thermal cracks, extra caution must be exercised during processing.
When performing CNC machining of titanium, ensuring the accuracy and stability of the processing equipment is the primary condition. Common processing equipment, such as vertical machining centers, horizontal machining centers and boring machines, need to be equipped with high-speed cutting, intelligent tool changing systems and precise measuring devices. At the same time, the following points should also be noted during processing:
1. Cutting speed control: The cutting speed of titanium needs to be strictly controlled. Excessive speed may cause damage to the cutting edge, which may lead to thermal cracking problems.
2. Infeed strategy: Directly penetrating into the material may cause scratches and tool damage, so appropriate pretreatment measures should be taken before infeed, such as using pre-drilled holes or oblique infeed, to reduce scratches and tool wear.
3. Cutting fluid management: Cutting fluid plays a key role in CNC machining of titanium. Its quality and stability directly affect the processing effect and tool life. Therefore, the selection and management of cutting fluid must be strictly controlled.
4. Post-processing process: Titanium CNC machining parts usually need to undergo surface treatment processes such as sandblasting, polishing, and electrochemical treatment after processing to improve their appearance and performance.
To sum up, titanium CNC processing requires fine process design, high-quality processing equipment and strict processing management. By optimizing cutting parameters, selecting appropriate feed strategies, ensuring the quality and stability of cutting fluids, and adopting appropriate post-processing processes, the quality and efficiency of CNC machining of titanium can be significantly improved.
