MACHINING RECOMMENDATIONS COOLANT GUIDE

SUCCESSFUL MACHINING OPERATIONS DEPEND ON CORRECT COOLANT APPLICATION In machining stainless steel, please verify and respect the cutting speed TURNING

Coolant is always recommended for High-Temp Alloys (Group S) and Aluminum NX-CNMP-TNMP-WNMP (Group N). Exotic Material In machining exotic materials, it is important to verify cutting conditions of the MILLING

• Coolant in drilling is always recommended independent of workpiece material as it helps chip evacuation, improves hole quality and increases tool life.
