Titanium CNC Turning
CNC turning of titanium shafts, fittings, and threaded components where concentricity, thread accuracy, and controlled tool engagement matter. Live tooling and sub-spindle finishing reduce handling on high-cost Ti-6Al-4V and Grade 23 stock.
- Typical Tolerance
- ±0.0005"
- Common Grades
- Grade 2 · Ti-6Al-4V (Grade 5) · Grade 23 (Ti-6Al-4V ELI)
- Production
- Prototype → Repeat Production
- Machine Type
- Mazak Quick Turn 250MSY (live tooling, sub-spindle)
Why Titanium Is Suited to CNC Turning
CNC Turning pairs well with titanium when setups are rigid and parameters are disciplined. Titanium's low thermal conductivity concentrates heat at the cutting edge and its work-hardening tendency penalizes rubbing, so controlled engagement and coolant strategy protect tool life and surface integrity.
Efficient production of rotational titanium geometry with concentricity control
Live tooling reduces secondary operations on aerospace and medical parts
Sub-spindle finishing supports done-in-one production for higher-cost stock
Controlled engagement manages titanium's heat and work-hardening tendencies
Machining Titanium on CNC Turning
Titanium has low thermal conductivity, so heat concentrates at the cutting edge instead of leaving with the chip. Combined with a tendency to work-harden and galling risk against unsuitable tooling, the process demands rigid setups, controlled cutting parameters, high-pressure coolant, and disciplined tool-life management.
Low thermal conductivity concentrates heat at the tool tip — coolant strategy is critical.
Work hardening penalizes shallow cuts and rubbing; feed engagement stays deliberate.
Rigidity in the workholding, spindle, and tooling reduces chatter and improves tool life.
Chip control matters — stringy chips can damage finished surfaces and increase downtime.
Titanium grades we machine

What titanium grades can Northline machine with CNC Turning?
We routinely machine Grade 2, Ti-6Al-4V (Grade 5), Grade 23 (Ti-6Al-4V ELI) on CNC Turning for prototype and production programs. Additional grades can be sourced for qualified programs — discuss requirements at RFQ.
What tolerances are typical for Titanium CNC Turning?
Typical ±0.001", with ±0.0005" achievable on qualified features. Achievable tolerances depend on geometry, material grade, feature depth, and production quantity. Final targets are confirmed at quote review.
Is Titanium suitable for CNC Turning?
Yes. Titanium is routinely produced on CNC Turning for aerospace and medical programs when setups are rigid and parameters are disciplined to control heat and tool wear.
Can you provide material certifications for titanium?
Yes. Material certifications with traceability to certified mill stock are available for Titanium on request. Confirm documentation requirements at RFQ.
Do you support both prototype and repeat production runs?
Yes. Prototypes are programmed, fixtured, and inspected the same way production parts are, which keeps the path to a qualified titanium production program short and predictable.
