The above mentioned indications are standard values. In some cases it may be advanta-
geous to increase or decrease these values.
A cooling or lubricating agent should be used when drilling.
For stainless materials (e.g. VA – or NIRO steel sheets) do not centre, as this will result in
the material compacting and the drill bit rapidly becoming blunt.
The workpieces need to be tensed inflexibly and stably (vice, screw clamp).
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 environmentally friendly emulsion as cooling lubricant procured from a
specialist retailer.
Make sure that the cooling lubricant is properly absorbed. Respect the environment when
disposing of lubricants and coolants. Follow the manufacturer's disposal instructions.
