CNC Machining of Titanium Alloys

Titanium gives you the strength of steel at roughly half the weight, plus corrosion resistance and biocompatibility. It also fights back at the cutting edge more than almost any structural metal.

Material overview

Why it is hard to machine

Titanium conducts heat poorly, so the heat a cut generates stays in the tool instead of leaving with the chip. Combined with high chemical reactivity, that shortens tool life and risks smearing. Low stiffness relative to its strength makes thin sections prone to chatter and deflection.

Machining challenges

Process controls that matter

Heat concentrated at the edge

Conductivity is low, so cooling and moderate surface speeds matter more than raw power. We keep the cut cool and the chip moving.

Rapid tool wear

Titanium is chemically aggressive at temperature. Sharp, dedicated geometry and strict tool-life limits protect tolerances.

Chatter and deflection

Thin walls flex easily. Rigid, low-force workholding and reduced radial engagement keep the part stable.

Frequently asked questions

Commercially pure Grade 2 and the Ti-6Al-4V alloy (Grade 5) are our standard grades; others on request.
Typically ±0.005 mm on 3-axis work and ±0.01 mm standard on simultaneous 5-axis, confirmed per drawing after DFM review.
Yes - lower cutting speeds, faster tool wear and longer cycle times all add cost. A DFM review usually finds geometry that cuts it back.
