Comparison of roughing process time
Cutting method | Tool | Vc m/min | n min-1 | Vf mm/min | fz mm/t | ap mm | ae mm | Max. chip removal volume | Actual cutting time |
Contouring | Conventional Ball End Mill | 176 | 7,000 | 1,800 | 0.13 | 0.4 | 1.2 | 0.86 | 118min. |
Contouring | EHHB4080-ATH | 176 | 7,000 | 3,600 | 0.13 | 0.6 | 1.8 | 3.9 | 34min. |
Helical cutting Trochoidal cutting | EHHB4080-ATH | 150 | 5,000 | 2,860 | 0.12 | 9.0 | 0.5 | 12.9 | 22min. |
This is the Point!
New proposal for direct cutting of hardened steels
4-flute ball end mill enables high-cutting-depth high-feed-rate cutting of hardened steels.
Provides more than 4 times the cutting efficiency of conventional 2-flute ball end mills.
In addition, use of new cutting methods combining helical cutting (oblique cutting) and
trochoidal cutting (side surface cutting) achieves greatly reduced cutting times.
