Best Titanium CNC Machining Shops
Titanium alloys (Ti-6Al-4V, Ti-6Al-4V ELI, Ti-3Al-2.5V) offer an exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility — making them indispensable in aerospace structures, jet engine components, medical implants, and high-performance motorsport. However, titanium is notoriously difficult to machine: it generates high cutting temperatures, work-hardens readily, and requires sharp tooling, high-pressure coolant, and experienced process engineers. The shops on this list have documented titanium machining experience and the equipment to do it right.
Why these suppliers?
- ✓Titanium requires specialized cutting parameters, premium carbide or PCD tooling, and high-pressure coolant — shops without titanium experience frequently produce scrapped parts, causing costly delays on aerospace and medical programs.
- ✓These shops have demonstrated titanium capability through actual program experience, not just theoretical capability — they understand titanium's tendency to work-harden and the importance of sharp, non-coated tooling for some grades.
- ✓For medical titanium (Ti-6Al-4V ELI), listed shops maintain documented procedures for biocompatibility traceability, surface finish compliance, and passivation where required.

Why is titanium machining more difficult than steel or aluminum?
Titanium has low thermal conductivity, which causes heat to concentrate at the cutting edge rather than being carried away in chips. This causes rapid tool wear and can cause work hardening of the machined surface if feeds and speeds are too low. Titanium also has a strong tendency to gall on the tool face, requiring sharp cutting edges and appropriate coatings (or uncoated carbide for some grades). High-pressure through-coolant is essential for chip evacuation and temperature control.
What titanium grades do CNC shops commonly machine?
The most commonly machined titanium grades are Ti-6Al-4V (Grade 5, the workhorse for aerospace structural and engine parts), Ti-6Al-4V ELI (Grade 23, for medical implants where reduced interstitial content is required), and commercially pure titanium CP-Ti Grades 1–4 (for chemical processing, marine, and corrosion-resistant applications). Ti-3Al-2.5V (Grade 9) is common in hydraulic tubing and aerospace fasteners.
What certifications should a titanium machining shop have for aerospace work?
For aerospace titanium parts, the CNC shop should hold AS9100 certification at minimum, and ideally Nadcap accreditation if the part drawing calls for special processes such as chemical milling, anodize, or thermal processing. ITAR registration is required for defense programs. Material certifications (mill certifications with full chemical and mechanical property data) must be maintained for traceability, and a first-article inspection report (FAIR per AS9102) is standard.
