Feature
▶ Designed to machine high hardened materials.
▶ Suitable for dry cutting, high speed cutting thanks to newly developed raw-material and new coating.
▶ Excellent workpiece finish.
▶ Designed for high precision milling operation.
▶ Higher wear -resistance.
High Feed End Mill Capabilities :
High speed roughing
High speed finishing... Mirror-like surface
▶ More number of flutes than the normal 2F ball E/M results in high-feed cutting. For X - Y wide cutting pitch, high effective cutting performs in short tool working time.
(Example of performance : for the material HRc 50~55)
| ITEM | SIZE | RPM | FEED | DEPTH OF CUT | |
| Z(mm) | X-Y(mm) | ||||
| HIGH FEED END MILL | 4F Ø10 X R2 | 5,400 | 11,000 | 0.2 | 3.0 |
| NORMAL BALL END MILL | 2F Ø10 X R5 | 7,500 | 2,500 | 0.2 | 0.5 |
▶ For cutting on slopes and corners, the remaining part to be cut is smaller than one that remains after working with normal ball End Mill. It saves the time and cost
▶ By using straight flute, the rigidity of corner radius is improved. And it's also possible to get less damage to end teeth and radius than normal radius End Mill.
