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.
