Machining with coolant is recommended for Ni-base Heat Resistant Alloy and Titanium Alloy. : 1st Recommendation : 2nd Recommendation
RDGT / RPGT are recommended for Stainless Steel, Ni-base Heat Resistant Alloy, and Titanium Alloy.
The figure in bold font is the starting value of the recommended cutting conditions.
Adjust the cutting speed and the feed rate within the above conditions according to the actual machining situation.
Recommended feed rate is the reference value when D.O.C. is r/2 (0.079" for RD..08 / 0.098" for RP..10 / 0.118" for RP..12 / 0.158" for RP..16).
For other D.O.C., calculate the recommended feed rate based on the conversion factor below.
For MRX16-S16-08-2T(-160), MRX16-W-08-2T, MRX20-S20-10-2T(-180), MRX20-W20-10-2T, MRX0625-W625-08-2T, MRX0625-S625-08-2T-6
set the feed rate no higher than 50% of the recommended cutting conditions.
