1. High-precision and complex shape processing
Precision size control: CNC machine tools can achieve high precision and meet the requirements of parts size in aerospace, medical implants and other fields.
Complex geometric forming: Through multi-axis linkage processing, complex curved surfaces and special-shaped structures (such as impellers and bone implants) that are difficult to achieve by traditional methods can be manufactured.
2. Overcome the difficulties of titanium alloy processing
Thermal control and tool wear：
Titanium alloy has poor thermal conductivity and is prone to high temperature when cutting. CNC can control heat accumulation by optimizing cutting parameters (speed, feed) and coolant injection.
Use special tools (such as cemented carbide and coated tools) to reduce wear and tear, and CNC's automated tool change system ensures processing continuity.
Work hardening response: The stable cutting force and continuous feed of CNC can avoid the performance degradation of parts caused by local hardening.
3. Improve material utilization and cost control
Near-net forming: optimize the cutting path through programming to reduce material waste, especially for expensive titanium alloys.
Reduce subsequent processing: complete multiple processes (milling, drilling, tapping) in one clamping, reducing labor and time costs.
4. Meet special performance requirements
Surface integrity: CNC can control the surface roughness to avoid microscopic defects affecting fatigue strength (such as aircraft engine parts).
Stress control: Adjust the residual stress distribution through processing parameters to improve the anti-crack propagation ability of parts.
5. Consistency and repeatability
Mass production stability: The CNC program guarantees the consistency of the processing of each part, which is suitable for medical, aviation and other fields that need to be certified.
Quick adaptation and adjustment: modify the program to adapt to design changes and shorten the R&D cycle.
The goal of CNC machining of titanium alloy is: under the premise of ensuring high performance and high reliability of parts, precision manufacturing of complex structures can be achieved at a controllable cost, while solving the inherent processing challenges of titanium alloy.Its value is more prominent in the field of high-end manufacturing, and it is the key technical means for the transformation of titanium alloys from “difficult-to-process materials” to “high-performance parts”.
