Tool Change
12.1
With Quick Clamping Device (Standard)
The tools used on the machine must comply with EN 847-1!
Wear cut-resistant protective gloves when changing tools!
•
Before changing the tool, switch off the spindle drive with the button (see
Then wait approx. 15 seconds
→
The motor brake opens automatically

•
Press one of the two emergency stop buttons (
4
) and leave it locked.
Figure 15: Milling arbor with quick clamping device
1.
Loosen the clamping screw (
C
) on the quick-re-
lease nut (
M
) with the supplied SW4 pin spanner.
2.
Then fully tighten the fixing
screw (
F
) by hand and remove
the quick-release nut (
M
) by
taking it out.
3.
Remove the spacer rings (
D
)
and put on the new cutter head.
Ensure that the clamping surfaces of the
spacer rings and clamping nut are clean.
Figure 16: Marking for upper spacer ring
4.
Put on the required spacer rings (
D
), if necessary.
Place enough spacer rings so that the upper
clamping surface of the upper ring is in the area
(
E
) of the marking groove shown in
5.
Then put the quick-release nut (
M
) back on and
tighten the fixing screw (
F
) by hand.
6.
Now tighten the clamping screw (
C
) with the SW4
pin spanner
→
Tightening torque =
12 Nm
.
With 12 Nm tightening torque of the
clamping screw (C), the cutter is clamped
with approx. 30 KN (= 3 t).
•
After the tool change, unlock the emergency stop button (
4
) again
.
12.2
With HSK 80 Tool Changing System (Option)
Instead of the rigid 30 mm milling spindle fitted as standard, the optional HSK 80 quick-change system uses a
milling arbor
2
(Ø 30 mm) with spindle locking device. This allows a quick and convenient tool change of the com-
plete milling arbor. The supplied SW8 pin spanner (with lateral magnet) is required for the exchange procedure.
The condition of the tool spanner must be checked occasionally. Using a pin spanner with
worn edges can lead to the destruction of the clamping cartridge.

Milling arbors with diameters of 35, 40 and 50 mm as well as 1¼" are also optionally available (see
0).
