チタン合金の硬度がHB350を超えると、旋削とフライス加工が特に困難になります。. チタンの硬度がHB300未満の場合, 固着現象が起こりやすい, CNC切断も難しい. しかし、チタン合金の硬さは、切断が難しい一側面にすぎません。.

チタン合金のCNC旋削およびフライス加工のプロセス, 注意すべき事項は:
(1) チタン合金は弾性率が小さいため、, 加工時のワークのクランプ変形や力変形が大きい, ワークの加工精度が低下します; ワークを取り付ける際のクランプ力は過大にならないようにしてください。, 必要に応じて補助サポートを追加できます.

The drilling is semi-closed CNC cutting. The cutting temperature is very high in the process of drilling titanium alloy, the rebound after drilling is large, the drill chips are long and thin, easy to stick and not easy to discharge. Drilling of titanium often causes the bit to be bitten, twisted, 等々. したがって, the drill bit is required to have high strength and good rigidity, and the chemical affinity between the drill bit and the titanium alloy is small. It is best to use cemented carbide drills, but the most commonly used at present is still twist drills, after taking some measures to improve, better results can also be achieved.

When high-speed milling of TC4, Gc.2, and pure titanium integral structures, down-milling is generally used. The tool slowly cuts into the titanium workpiece to reduce the heat generated and reduce the radial force.
When milling titanium alloy TC4 (Ti-6Al-4V), asymmetric down milling is often used, so that the front tip of the cutter tooth first contacts the workpiece.
