티타늄 CNC 가공용 공구 재료 선택 방법?

티타늄 합금의 CNC 가공은 두 가지 측면에서 시작되어야 합니다.: 절삭 온도 감소 및 접착력 감소. 열경도가 높은 공구 재료 선택, 높은 굽힘 강도, 좋은 열 전도성, 티타늄 합금과의 친화력이 좋지 않음. YG 초경합금이 더 적합합니다. 고속도강의 내열성이 좋지 않기 때문에, 가능한 한 초경합금으로 만든 공구를 사용해야 합니다.. 일반적으로 사용되는 초경합금 공구 재료로는 YG8이 있습니다., YG3, YG6X, YG6A, 813, 643, YS2T 및 YD15.

Coated blades and YT-type cemented carbide will have a violent affinity with titanium alloys, aggravating the bonding wear of the tool, and are not suitable for cutting titanium alloys; For complex and multi-edged tools, you can choose high-vanadium high-speed steel (such as W12Cr4V4Mo), high-cobalt high-speed steel (such as W2Mo9Cr4VCo8) or aluminum high-speed steel (such as W6Mo5Cr4V2Al, M10Mo4Cr4V3Al) and other tool materials. It is suitable for making drills, reamers, end mills, broaches, taps and other tools for cutting titanium alloys.

Using diamond and cubic boron nitride as tools for cutting titanium alloys can achieve significant results. If natural diamond tools are used under the condition of emulsion cooling, the cutting speed can reach 200 m/분; If cutting fluid is not used, the allowable cutting speed is only 100m/min at the same amount of wear.
