8 tips on machining titanium and its alloys

Dense machine construction will absorb vibration and cutting loads better than one designed for light duty machining. Invest in a high-performance machine tool if you're serious about machining titanium. High speed can produce a chemical reaction between the chip and the cutting tool material, which can result in sudden insert chippings/breakages.
