Setting The Milling Width Or Assembly Of The Adjustable Groove Cutter; Assembly Of The Slitting Unit; Reversible Knife Change And Setting "Adjustable Groove Cutter - Mafell MF 26 cc Traduction De La Notice D'emploi Originale


Push the slitting unit or adjustable groove cutter
onto the shaft.

Tighten the flange screw 5 (Fig. 4) by turning it
clockwise with the Allen key.

Close the saw guard cover. To this end, close
the cover and press the locking lever 3 (Fig.5)
downwards.
4.8 Setting the milling width or assembly of the
adjustable groove cutter
The adjustable groove cutter 30 (Fig. 9) is a
reversible knife adjustable groove cutter, which can
be adjusted to milling widths between 15.4 and 25.0
mm (39/64 – 63/64 in.). Spacers in the following
thickness are included with the adjustable groove
cutter: 5 / 2 /1 / 0.5 (2x) / 0.3 (2x) / 0.1 (approx. 13/64,
5/64, 3/64, 1/32 - 2x, 1/64 – 2x, 1/128 in.).
With these you can create interim widths in 0.1 - 0.2
mm (0.004 – 0.008 in.) steps.
Proceed as follows:

First compile the required adjustable groove
cutter width with the enclosed spacers (the
adjustable groove cutter without spacers has a
groove width of 15.4 mm (39/64 in.)).

To assemble the individual parts of the
adjustable groove cutter, first the spacers that
are not required are pushed onto the front
flange 31 (Fig. 9). Attention must be paid that
the largest spacer thickness is always the first to
rest on the clamping flange.

Afterwards, first place the front part of the
adjustable groove cutter (the side with the
lettering) onto the flange.

Then place the required spacers onto the
flange.

Fit the rear part of the adjustable groove cutter
onto the flange and press the entire unit
together (possibly while twisting it slightly) until
the front flange engages with the rear flange.
The adjustment range specified on
the adjustable groove cutter may
on no account be exceeded.
Ensure that all the enclosed
spacers are fitted at all times.

4.9 Assembly of the slitting unit


Take the rear mounting of the slitting unit (star-
shaped opening in the bore) with the short
diameter into your left hand.

Push the saw blade onto the mounting diameter
such that the saw teeth above the mounting are
pointing towards you.

Push a spacer onto the mounting.

Repeat the procedure with saw blade and
spacer in the same sequence twice more.

Fit the front flange with the integrated flange
screw into the bore and twist the flange while
exerting a slight pressing movement until the
flange engages.
4.10 Reversible
"Adjustable groove cutter"
The adjustable groove cutter 30 (Fig. 9) is equipped
with 4 carbide reversible knives 32 and 4 carbide
precutters 33. If the blades are becoming blunt, you
can turn the reversible knife 32 (Fig. 9) thrice and the
reversible knife 33 (Fig. 9) twice. After that, new
original reversible knives must be fitted!
Proceed as follows:

Dismantle the adjustable groove cutter 30 (Fig.
9) from the machine as described in 4.8.

Unscrew the countersunk screws 34 (Fig. 9)
using the torx screw driver.

Clean all parts and the knife chambers of the
adjustable groove cutter.

Turn or replace the reversible knives 32 and 33.

Fasten the
countersunk screws and retighten these with the
torx screw driver (4 Nm).
The two parts have been inserted correctly if the rear
of a knife 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 reversible
knife (see Fig. 9). The radial blade protrusion of max.
1.1 mm (3/64 in.) is thus guaranteed.
