Abstract (en)
[origin: EP2147755A2] The boring machine has an electromagnet (14) for attachment to a metal part (28). An electric motor (20) is provided for driving a tool (36), where a control unit comprises a switch (34) for switching on and off the electric motor and the electromagnet. A speed sensor (21) is coupled to the control unit, such that the electromagnet is switched off when the electric motor has a speed less than or equal to a limiting speed. An independent claim is included for a method for controlling a boring machine.
