INFORMATION
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.
INFORMATION
Use a water-soluble and non-pollutant emulsion as a cooling agent. This can be acquired from
authorised distributors.
Make sure that the cooling agent is properly retrieved. Respect the environment when dispo-
sing of any lubricants and cooling agents. Follow the manufacturer’s instructions for disposal.
