Friction during the cutting process causes high temperatures at the cutting edge of the tool. The
tool should be cooled during the milling 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. This can be acquired from
authorized distributors.
Make sure that the cooling agent is properly retrieved. Respect the environment when disposing
of any lubricants and cooling agents. Follow the manufacturer’s disposal instructions.
