Titanium Machining Expertise

Engineering Know-How

Decades of hands-on metallurgical experience solving titanium's unique machining challenges through engineered process solutions.

Challenge: Low Thermal Conductivity

Problem — Titanium's poor heat dissipation (≈ 7 W/m·K) causes rapid tool-edge temperatures exceeding 1,000°C, accelerating flank wear and compromising surface integrity.

Our Solution

High-pressure coolant delivery at 70+ bar directly to the cutting zone evacuates heat instantly, prevents built-up edge formation, and extends tool life by up to 300%.

Engineering Implementation
  • Through-spindle coolant (TSC) at 70 bar minimum pressure
  • Cryogenic CO₂ or liquid nitrogen cooling for roughing operations
  • Sharp positive-rake geometries with TiAlN+ coating
  • Reduced cutting speeds (30–60 m/min) with increased feed rates

Challenge: Chattering & Deformation

Problem — Titanium's low elastic modulus (≈ 110 GPa) induces workpiece deflection and regenerative chatter during machining, especially in thin-wall and deep-cavity geometries.

Our Solution

5-axis simultaneous machining with rigid fixturing and dynamic vibration damping eliminates chatter marks and holds micron-level tolerances on complex titanium structures.

Engineering Implementation
  • Hydrostatic workholding with custom soft-jaw fixturing systems
  • Dynamic stiffness analysis (FEA-optimized) for thin-wall components
  • Adaptive trochoidal toolpaths with constant chip-thickness algorithms
  • Real-time spindle load monitoring with automated feed-rate override

Our process engineers have logged over 50,000 hours of titanium-specific machining across all 7 grades.
