Thermal Stress & Deformation Control in 5-Axis Grade 5 Milling
High-pressure through-tool coolant (70–150 bar) directly at the cutting zone keeps the cutting edge ~35% cooler, eliminating thermal drift on 200 mm+ aerospace structural frames.
- HPC pressure (through-tool)≥ 70 bar (peak 150 bar)
- Cutting edge temperature−35% vs flood
- Thermal drift budget≤ 0.005 mm / 200 mm
- 5-axis CNC (HSK63, through-tool prepped) — 8000 rpm spindle, 0.001° rotary axis
- High-pressure coolant system — 70–150 bar, dual-stage filtration 5 µm
