Dimension of NACHI GS MILL Ball ø1mm – ø12mm 2GSR (2GSR5R) LIST9386:
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.
- When using low speed machines, use the maximum speed and adjust the feed rate.
- In grooving stainless steels, reduce the rotation to 60% of table values and the feed to 40% of table values.
- Use in wet-condition in case of Stainless Steels, Nickel Alloys and Titanium Alloys.
- Adjust milling condition when an 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。
