ORCA AX 10 ORCA MX 10 ORCA WX 10 - Dr. Bender GmbH

1.0 General Notes
1.1 Technical description
ORCA represents a completely new generation of driving machines and core drills. In the process, quite
newly developed high frequency elements are employed in the motor. The frequency range is adjusted
within 0 – 1000 Hz by means of the integrated frequency changer. At 1000 Hz, the rotor reaches a speed of
30,000 min -1 . A main advantage results from a weight / performance ratio (motor output = 11 kW / weight =
21.5 kg -> 0.51) so far unequaled with the conventional technology, such as the BBM33extra type (motor
output = 2.4 kW / weight = 13.5 kg -> 0.17). This means that the weight of the machine could be reduced
three times by means of the high frequency technology. Further advantages result from the infinitely
variable speed regulation. Thus, each core bit diameter may be assigned its optimum speed, in order to
achieve the best cutting speed possible at the tool. Furthermore, the speed may be continuously reduced
during the drilling process when steel reinforcements appear, thus providing its optimum adaptation to the
drilling progress. The WX 10 ORCA features a further essential advantage in comparison with conventional
drilling motors: the torque behaviour. The very high torque (in the first gear, approx. 750 Nm, in the second
gear, approx. 350 Nm) is available throughout the entire speed range. In this case, it is possible to run at
much higher cutting speeds (Caution! They depend on the tool), achieving an up to 150% faster drilling
progress. In the case of conventional machines, the torque dramatically decreases at high speeds,
rendering this advantage impossible.
1.2 Application
The driving machines and core drills can be used for the purposes outlined by the data on the model plate.
If you are using special machines, the details in the quotation and order confirmation also apply.
The driving machines and core drills are supplied as standard in protection class I; only this can guarantee
the full high quality protection of the FI switch.
If you use suitable core bits, you will be able to drill in the most diverse material types:
- concrete (even if it contains thick reinforcement steel)
- sandstone and limestone
- all building materials for solid walls
- asphalt carpets
The core drills comply with the regulations of the ”Stone and Earth” Professional Association of July 1989.
They are machines of category II, which means they have to be guided on stand and be stable (according
to DIN 57100 and VDE 0100, respectively); the stand must be
- provided with non-return lock.
The machine must be
- connected to a duly grounded EEC socket (EEC 5poles, 3P+PE 32A 6h – 400V); no zero
conductor is required;
- operated with a pre-connected FI protection in order to ensure the protection of the operator.
