Recommended cutting conditions

Recommended insert grade (Vc: m/min) Note

WorkpieceMEGACOATCarbide1) The standard cutting speed is Vc = 30 ~ 50 m/min
PR1225GW05The table feed may not follow the expected conditions when machining small
Carbon steel • Alloy steel–diameter workpieces at high speeds

30 ~ 50 2) Coolant is recommended Stainless steel – 30 ~ 50

Non-ferrous metals – 30 ~ 50 : 1st recommendation
