CNC Turning for Titanium Grade 5 (Ti-6Al-4V)

Turning titanium Grade 5 requires careful parameter control due to its poor thermal conductivity, high strength, and chemical affinity with tool materials. Rigid setups and sharp tooling are mandatory.

Recommended Machining Parameters

ParameterValue
Achievable Tolerances±0.01 mm (±0.0004")
Surface FinishRa 0.8-3.2 μm
Cutting Speed40-80 m/min

Tooling RecommendationsUncoated carbide (S grade) or PVD coated. Sharp positive inserts. Consider PCD for finishing.

Expert Machining Tips

1

Low cutting speeds — heat has nowhere to go

2

Maintain positive chip flow at all times

3

High-pressure coolant aimed precisely at cutting zone

4

Use C-style or rhombic inserts for better heat dissipation

5

Never recut chips — they work-harden instantly

Common Parts Made

Medical implant shafts

Aerospace fasteners

Turbine shaft sleeves

Valve stems

Racing axle components

Machining Challenges

  • Chemical reaction with tool coatings
  • Chip can ignite if too thin
  • Spring-back causes dimensional issues
  • Requires specialized coolant management
