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

5-axis machining is essential for titanium aerospace components with complex geometries. It reduces setups and improves accuracy while the continuous tool engagement helps manage titanium's poor thermal conductivity.

Recommended Machining Parameters

ParameterValue
Achievable Tolerances±0.01 mm
Surface FinishRa 0.8-3.2 μm
Cutting Speed30-60 m/min
Feed Rate0.08-0.15 mm/tooth
Tooling RecommendationsUncoated or PVD-coated carbide. Ball nose for profiling. Barrel cutters for surface finish efficiency.

Expert Machining Tips

1

Keep constant chip thickness at all angles

2

Program with tilt to avoid center-of-ball contact

3

Through-spindle high-pressure coolant is mandatory

4

Verify collisions extensively — titanium mistakes are expensive

Common Parts Made

Turbine blades

Structural aerospace fittings

Medical implant geometries

Blisk components

Landing gear fittings

Machining Challenges

  • Very slow material removal rate
  • Highest tooling cost of any material
  • Fire risk with titanium chips
  • Machine hours per part can exceed 40+
