The above mentioned indications are standard values. In some cases it may be advanta-
geous to increase or decrease these values.
When drilling a cooling or lubricating agent should be used.
For stainless materials (e.g. VA – or NIRO steel sheets) do not center as the material would
compact and the drill bit will become rapidly blunt.
The workpieces need to be tensed in flexibly and stably (vice, screw clamp).
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. By cooling with an appropriate coolant lubricant
you will achieve a better working result and longer durability of the tool.
INFORMATION
Use a water soluble environmentally compliant emulsion as cooling agent procured from the
specialized trade.
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.
INFORMATION
The CNC milling machine is lacquered with a one-component paint. Observe this fact when
selecting your cooling lubricant.
