5.3 - Bed
Support structure for the operating head (rotating arm for gradual
cutting, with respective blocking system), the vice, the bar stop and
the housing for the cutting coolant tank.
6 DESCRIPTION OF THE OPERATING CYCLE
Before operating, all the mains organs of the machine must be set in optimum conditions (see chap-
ter 7; “Regulating the machine”).
6.1 - Starting up and cutting cycle
•
Ensure that the machine is not in emergency stop con-
dition; if it is, release the red mushroom button (1).
•
Place material to be cut in the vice (3) and clamp the
part into place by handwheel (5).
•
Grip the handle (4) of the head control arm and press
the button (2), checking that the blade is turning in the
direction indicated (if not, invert the two phase leads)
and that sufficient coolant is coming out.
The cropper is now ready to start work, bearing in mind
that the cutting speed and the type of blade - combined
with a suitable descent of the head - are of decisive impor-
tance for cutting quality and for machine performance.
•
When starting to cut with a new blade, in order to
safeguard its life and efficiency, the first two or three
cuts must be made while exerting a slight pressure on
the part, so that the time taken to cut is about double
the normal time. For further details, please see chapter
9.5; “Running in the blade”.
•
Press the red emergency button (1) when there are
conditions of danger or malfunctions in general, so as
to stop machine operation immediately.
7 REGULATING THE MACHINE

If excessive axial play is found on the hinge, it will be sufficient to tighten the screws (6), paying
attention not to make the joint too tight.
7.2 - Vice
The devices do not require any particular adjustments.
