Dimension of NACHI GS MILL Hard Ball ø0.4mm – ø12mm GSBH LIST9422:
High-speed processing of high-hardness materials With the newly developed ultra-aluminum-rich Al-Ti-Cr laminated coating “GS Hard Coat” Increased oxidation resistance at 1100 ° C more than 3 times as much as before Improved heat resistance and wear resistance in ultra-high speed machining The surface roughness of the surface layer is very smooth like the conventional GS coat and reduces frictional resistance during cutting.

NOTES:
- Use highly rigid machining center.
- Recommend oil mist process.
- When depth of the cut is small, can increase feed speed more.
- When using low speed machines, use the maximum speed and adjust the feed rate.
- Adjust milling condition when unusual vibration, different sound occur by cutting.
- ワークや機械により振動や異音が発生するときは、 状況に応じて切削条件を変更してください。
