Question 1

Why does titanium TA6V machining require specific expertise?

Accepted Answer

TA6V has a specific cutting force Kc of ~1,500 MPa — 30–50% higher than 316L stainless. Its low thermal conductivity (6.7 W/m·K vs 50 W/m·K for mild steel) means 80% of cutting heat remains concentrated on the cutting edge. Without an adapted protocol, temperature reaches 700°C in seconds, causing catastrophic wear and built-up edge (BUE). The high elastic springback (Young's modulus 114 GPa vs 210 GPa for steel) compromises tolerances on slender parts. We use MQL (Minimum Quantity Lubrication) or 80-bar high-pressure coolant, AlCrN/K20 coated submicron carbide tools, and sustained feed — never stopping the tool during a cut, as this creates a localised hot spot causing immediate galling.

Question 2

What is the difference between machining Inconel 718 and TA6V?

Accepted Answer

Both are difficult but for different reasons. Titanium TA6V suffers primarily from its low thermal conductivity and elastic springback: low cutting speed (30–65 m/min), sustained feed, MQL or high-pressure coolant, never stop the tool during a cut. Inconel 718, precipitation hardened (γ'' phase), is harder (HRC 36–40) and work-hardens rapidly — each pass must cut below the hardened layer with submicron carbide grade M20/M30 tools, 80-bar high-pressure coolant mandatory. Inconel wears tools 5–8× faster than steel. Both materials require preventive tool changes based on measured wear criteria, not arbitrary part counters.

Question 3

Do you produce titanium parts for the aerospace industry with EN 9100 certification?

Accepted Answer

Yes. Our EN 9100:2018 certification covers titanium machining for the aerospace industry and Inconel series production. We apply the First Article Inspection Report process (FAIR / EN 9102): full CMM report on all key characteristics (KCs), AMS material certificates, 10-year digital archiving. The FAIR is delivered with the first shipment. Our qualification package includes: control plan, process FMEA, Cpk ≥ 1.33 on KCs, and lot-by-lot traceability from bar stock to finished part.

Question 4

How do you manage the fire risk during titanium machining?

Accepted Answer

Finely cut titanium chips can spontaneously ignite when in contact with a heat source — this risk is real and documented. Three preventive measures are systematically applied: (1) integrated chip-breaker tool geometry to fragment long filamentary chips from formation, (2) 80-bar high-pressure coolant injected directly onto the cutting zone to immediately evacuate chips and cool the edge — stopping the tool during cutting is strictly prohibited as it creates a hot spot generating sparks, (3) machines equipped with closed guards with forced chip extraction into sealed bins. Titanium chips are treated as hazardous waste and recycled through specialist channels.

Question 5

Do you also offer CNC aluminium machining alongside titanium?

Accepted Answer

Yes. Our machine shop handles aluminium CNC turning (2017A, 7075 T6, 6061 T6) and precision light alloy machining in the same quality environment as titanium. Aluminium precision turning benefits from high cutting speeds (300–600 m/min), PCD or uncoated submicron carbide tooling, and adapted MQL lubrication. ±0.005 mm tolerances are maintained through thermal compensation on our high-speed CNC centres (18,000 rpm). Special alloy machining (Monel, Hastelloy) uses the same HRSA protocols as titanium and Inconel.
