Machining Titanium Grade 5 (Ti-6Al-4V) presents a unique challenge. The alloy’s low thermal conductivity and high chemical reactivity mean that excessive heat can concentrate near the cutting zone, causing premature tool wear, built-up edge, and surface micro-cracking.
High-Torque Spindles for Consistent Cutting Power
Titanium requires deeper engagement and slower speeds. XC Machining uses spindles that deliver 100–150 Nm of torque at low RPMs, maintaining constant power throughout the cutting stroke. This ensures uniform chip thickness, stable tool load, and consistent surface integrity during roughing and finishing operations.
Flood or High-Pressure Coolant Delivery
Because titanium dissipates heat poorly, heat management is critical. Our high-pressure coolant systems (up to 80 bar) flood the cutting zone with emulsion or oil-based coolants that both lubricate and cool the interface. The result is a drastic reduction in tool oxidation, galling, and micro-fracturing.
Advanced Tooling and Coatings
XC Machining employs CVD-coated carbide, PVD-coated inserts, and solid-carbide end mills treated with TiAlN / AlTiN / SiN layers. These coatings form a thermal barrier that allows the cutting edge to withstand temperatures above 800 °C without softening. This technology extends tool life by more than 40 % in continuous titanium milling.
Adaptive Tool Paths and CAM Optimization
Our CAM engineers use adaptive machining strategies, trochoidal milling, constant-chip-load paths, and 5-axis synchronized motion, to minimize dwell time, chatter, and deflection. These methods maintain a steady engagement angle and smooth chip evacuation, especially on thin-walled or contoured components.
Machine Rigidity and Damping
A titanium-ready CNC must suppress vibration. XC Machining’s frames feature reinforced bases and polymer-concrete damping structures to absorb harmonic energy during heavy cuts. This mechanical stability ensures micron-level accuracy and surface smoothness even during long production runs.
