Milling hardened steels from 55-70 HRc
Advantages:
- No electrical discharge machining required, milling is much more productive
- Program also in micro’s available
- Extreme high surface quality
- a single clamping for more accurate results
Different strategies possible:
| HPM (High Performance Machining) | HSM (High Speed Machining) |
| · High cutting speed (Vc)
· Large cutting depth (Ap) · Small cutting width (Ae) · Medium feed per tooth (Fz) / table feed (Vf) |
· High cutting speed (Vc)
· Small cutting depth (Ap) · Small cutting width (Ae) · Medium feed per tooth (Fz) / table feed (Vf) |
Tips:
- Use a rigid milling machine and clamping method
- Try to minimize entering and exiting the workpiece
- The use of minimum lubrication or oil-mist-spray is recommended
Leading technology for hardened steels (55-70 HRc):
- 2 Flute ballnose geometry from 0,1 mm: VHPK
- 4 Flute torus geometry from 0,2 mm: VHPT
- Multiple flute, available with extra teeth for high productivity: VHPM
- Multiple flute with corner radius and extra teeth: VHPMR
Coating:
- Multi-layer coating
- Extreme high tool life due to nano-structure
- Extreme hardness
