Important:
The machine was designed for preparation of weld surfaces. The accuracy of
machining is in the range of +/- 1 mm. Satisfactory results can be achieved only
under the condition that the edges of the material have been prepared perfectly.
Unfortunately, material is often burnt or sheared. These inaccuracies, of course,
have impact on the results of machining.
Important:
If it is difficult to machine the bevel in the number of steps recommended by us,
we recommend that you divide the process into multiple chips. The reason may
consist in wear and tear of the cutting tips or worse machinability of the material.
11.2
Bevelling
Connect the device to the compressed air distribution system and set the pressure
regulator to the max. value 6 bar.
Lubrication shall be set to the medium position.
After careful settings of the first draft (refer to section 11.1), hold the device with both
your hands, unlock the fuse of the starting valve and start the machine.
Put the machine on the material, so that the pressure/contact disc (fig. 10.0.1, position
F) touches the material with maximum of their surfaces.
Slowly get the machine closer to the material until you feel that the cutter is starting to
be engaged. CAUTION!!! Now, a kickback may occur. Therefore, be careful.
Move the machine further towards the material until the cutter is inserted in the
material in the entire profile of the set chip. Now the contact roller must touch the
workpiece edge. The pressure disc must lie flat with its surface on the material.
Now, you can start machining from left to right. The machine shall be moved constantly
only at the speed, so that the cutter is able to remove material in the set chip profile
continuously. Otherwise the cutter will be pushed out from the material and the bevel
will be uneven.
Caution:
While working, use working gloves and other personal protective equipment.
Maintenance operations must be performed with the still machine and after the
machine has been disconnected from the compressed air distribution.
Important:
The machining movement is always from the left to the right.
Caution:
Operators must hold the device with both their hands.
