Because of the high production performances obtained when high speed milling, HSC is becoming increasingly important in industry. The process enables exceptional removing rates to be achieved i.e. up to 1000 cm3/minute.
For the majority of the materials, the feed per tooth fz = 0.01 x D1 is an excellent starting point. This feed should be increased or reduced depending upon the result obtained, but it should remain within the following range :
Non ferrous materials | Vc (Cutting Speed) | Lubrication |
[m/min.] |
Aluminum | 1000 - 4000 | vaporisation |
Brass | 1000 - 2500 | vaporisation |
Copper | 600 - 1500 | vaporisation |
Titanium | 100 - 200 | vaporisation |
Graphite | 1000 - 4000 | compressed air |
Carbon fibres | 250 - 500 | compressed air |
Plastics | 300 - 1000 | compressed air |
The above mentioned conditions will have to reduced by 30 % when using Solid Carbide end mills (Long Style/Long Series).
Ferrous materials | Vc (Cutting Speed) | Lubrication |
[m/min.] |
Steels | 300 - 700 | vaporisation |
Cast Irons | 500 - 750 | vaporisation |
Inconel | 75 - 100 | vaporisation |
Maximum width and pass depth recommended (ae and ap).
| Contouring | Surfacing |
ap | 1.5 x D1 | 0.1 x D1 |
ae | 0.1 x D1 | D1 |
