INFORMATION
High temperatures are generated at the tip of the tool by the occurring friction heat. 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 dispos-
ing of any lubricants and coolants. Follow the manufacturer’s disposal instructions.
