Machining Titanium: A Practical Guide

Titanium is strong, light and notoriously tricky to cut. This guide covers the essentials to machine it cleanly.

Why titanium is hard to machine

Low thermal conductivity traps heat at the cutting edge, and the material work-hardens. The result: quick tool wear if you cut wrong.

Cutting strategy

Moderate speeds, higher feed per tooth, and never let the tool dwell in the cut. Keep the chip load positive and the coolant flowing.

Setup and tooling

Rigid workholding and sharp, coated carbide tools. Avoid long overhangs that let the part chatter and distort.

Grade choices

Grade 5 (Ti-6Al-4V) is the default; Grade 2 for formability; both need the same disciplined approach.

Frequently asked questions

Can titanium be milled to tight tolerance?

Yes — with rigid setups and stable temperatures, ±0.01 mm is routinely achievable.

Is titanium more expensive to machine?

Tool life is shorter and cycle times longer, so yes — but the performance often justifies it.
