11. Use
Important:
The device can be used solely if it is fitted with the original indexable inserts supplied by
our supplier, i.e. the device manufacturer. It includes four-sided indexable inserts. The
device can be fitted with 6 pieces of indexable inserts. It is prohibited to use other than
original inserts.
11.1 Setting the removal size
Attention :
During the adjustment operation, wear gloves and other personal protective
equipment. The operations must be carried out on the machine at rest and after
disconnecting from the power supply.
Disconnect the machine from electricity supply.
Release the setting arresting screws (fig.10.0.1 position F)
Turn the guiding plate (fig.10.0.1 position G) for setting the reduction size. You can
read the setting on the scale (fig.10.0.1 position C). Stupnice je pouze orientační a
výsledný úběr může být jiný při použití různých úhlů frézovacích hlav.
After setting, fasten both screws (fig.10.0.1 position F).
Important:
Maximum reduction is 15mm of bevel width (dimension P fig.11.1.1). The reduction can be
achieved in more steps. It depends on the material solidity. We recommend performing the
test.
Start with lower reduction and gradually increase the value until the work with the machine is
comfortable and the plates can achieve gradually reduction without increased vibrations. For
orientation setting, use the tables below.
We recommend administering the work log for recording the measured value and the
machining procedure.

10
Fig. 11.1.1
For orientation setting of the reduction size and the independent machining process, use
the setting tables for individual bevel angles.
Important:
The values in the table are calculated from point 0. Point is the point when the
miller touches the material edge for the first time. This point can be set by
gradual turning of the thrust plate (fig.10.0.1 position G) and placing to the
material edge.

Important:
The machine was constructed for the preparation of welded surfaces. Machining
accuracy is within limit
+/-1mm. The condition for reaching the satisfactory results is a perfect
preparation of the material edges. Unfortunately the material is often burned or
cut. The inaccuracy shall be reflected on the resulting machining.
Important:
If it is difficult to machine the bevel within the recommended number of steps,
we recommend dividing the process to more chips. The reason can be the wear of
the cutting inserts or worse machining properties of material.
11.2 Bevelling
Connect the device in electricity distribution
After careful setting of the first reduction, see clause 11.1, hold the device with
both hands and use the main switch to switch on the device.
Fit the machine on material in such way the thrust/contact plate (fig. 10.0.1 position
G) was in contact with material at maximum possible surface.
Slowly move the machine to the material until you feel the milling machine is in
reduction. CAUTION!!! The rebound is possible at this moment, be careful.
Press the machine in the direction into the material until the miller is embedded in
the material in the full profile of the set chip. Contact roller (fig. 10.0.1 position E)
must now touch the workpiece edge. The thrust plate (fig. 10.0.1 position G) must be
placed with the surface on material.
Now, you can start the machining from the left to the right. Shift the machine
constantly; using only such speed the milling machine was able to remove material
in the set chip profile. Otherwise, the milling machine will be pushed out from the
material and the bevel will be unequal.
Attention :
During work, wear gloves and other personal protective equipment.
The maintenance operations must be carried out on the machine at rest and after
disconnecting from the power supply.
Important:
The shift during machining is always from left to the right.

12
Attention :
The device operators must hold the device with both hands.
11.3 Bevel angle and shape change. Milling head replacement
Machine B15 ELECTRA is constructed for the use of more milling heads, see chapter
8. Accessories.
For the head replacement, proceed as follows.
Disconnect the machine from electricity supply.
Release the setting arresting screws (fig.11.3.1 position A) by the enclosed allen key
(fig. 11.3.1 position C)
Turn the guiding plate (fig.11.3.1 position B) for complete disassembly from the
machine
Secure the spindle against turning with the button, which is located on the top side of
the gearbox (fig 11.3.2 position A)
Use the allen key (fig.11.3.2 position D), release and disassemble the roller screw
(fig. 11.3.2 position C) and roller (fig.11.3.2 position B)
Now disassemble the milling head (fig.11.3.3 position F) by enclosed hook spanner
(fig.11.3.3 position E)
Use the same process to assemble new head and reassemble the machine.
All connections must be appropriately fastened.
