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
• Set correct RPM in the range of 4 - 6 on the plastic regulation wheel.
• 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.
Important:
B10 Electra allows to adjust RPM continuosly in the range 2700 - 8500 RPM.
Current RPM is possible to check on the setting regulation wheel, which is located
on the upper side of the motor house B10 Electra (values 1 - 6).
For bevelling of the steel is strictly recommended to use setting in the range 4 - 6
on that regulation wheel only.
In the case of the setting lower RPM there is the risk of the damading of the
gearbox due to too high vibrations.
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
