Reversing mode for core drilling systems
Abstract:
A control method for the use of a core drilling system including a core drill and a feed device for driving the core drill along a machine holding device. The method includes the steps of determining the end of a core drilling operation on the basis of reaching a predetermined threshold value for at least one corresponding predefined drilling parameter; and of selecting a reversing mode for retracting a drilling tool out of a borehole at a reversing rotational speed which corresponds to a multiple of a predetermined tapping rotational speed of the drilling tool at the beginning of the core drilling operation.
