Page 16: General Working Notes
3.10 General working notes 3.10.1 Coolant Friction during the cutting processes causes high temperature at the cutting edge of the tool. The tool should therefore be cooled during the cutting process. Cooling the tool with a suitable cooling lubricant ensures better working results and a longer edge life of the cutting tool. Use a water soluble and non-pollutant emulsion as a cooling agent. -
