4.5.2. Chips disposal
Chips resulting from cutting operations must be disposed of in accordance with
the relevant regulations.
•
Let the chips drip excess fluid!
•
Put the chips into a watertight container. Make sure that the container does
not leak, because even after a long dripping time, the chips still contain
coolant residues.
•
Place the container into the care of a disposal company equipped for the
disposal of chips contaminated with cooling liquid. In case the machine is
equipped with micronisation device, the chips must also be handed over to
a disposal company.
