Changing The Indexable Cutting Insert; Operation; General; Switching On And Off - Mafell PF80 Originalbetriebsanleitung

So as to guarantee its function, the machine is
harmonised with the milling cutter included in the
delivery, therefore only a corresponding spare part can
be used.
- The tool holder is locked with pushbutton 109.
- Release cylinder head screw 26 by means of the
hexagon wrench key.
- Replace the milling cutter 3 and tighten it again (10
Nm). Pay attention to the cylinder pins and ensure
that there are no chips on the clamping surfaces.
Deresinification is carried out by soaking the cutters for
24 hours in paraffin or commercially available resin
remover.

4.4 Changing the indexable cutting insert

Danger
Pull the power plug during all
service work.
Danger
Indexable cutting inserts are cutting
tools and have sharp corners and
sharp edges. Handle these
indexable cutting inserts with care
to prevent injuries and damage to
the inserts.
The milling head is equipped with 4 HM carbide
indexable cutting inserts. If the blades are becoming
blunt, you can turn the indexable cutting insert three
times. After that, new original indexable cutting inserts
must be fitted!
Follow the procedure below:
- Unscrew the countersunk screws using the torx
screw driver.
- Clean all parts and the cutter chambers of the
milling head.
- Turn or replace the indexable cutting inserts.
- Fasten the indexable cutting inserts with the
countersunk screws and retighten these with the
torx screw driver (4 Nm).
The parts have been inserted correctly if the rear of a
cutter edge is resting against the carrier body and the
countersunk screw can be screwed in that far that the
surface of the countersunk screw is located below or
on the same level as the surface of the indexable
cutting insert. The radial blade protrusion of max. 1.1
mm is thus guaranteed.
