Abstract
A cutting grinder for cutting through a rail of a track includes a detection device for detecting a proposed cutting position. The cutting grinder guarantees simple, user-friendly and efficient through-cutting of the rail.
Claims13
A cutting grinder for cutting through a rail of a track, the cutting grinder comprising:
- a base body;
- a drive for driving a cutting disc in rotation about a rotational axis;
- at least one handle for manually guiding the cutting grinder;
- a detection device including at least one sensor for detecting a first cutting position in which the cutting grinder is disposed on a first side of a rail symmetry plane, and for detecting a second cutting position in which the cutting grinder is disposed on a second side of the rail symmetry plane;
- and a control unit for setting a rotational direction of said drive in dependence on a respective cutting position detected by said detection device.

A method of cutting through a rail of a track, the method comprising the following steps:
- providing a cutting grinder with a base body, a drive for driving a cutting disc in rotation about a rotational axis, at least one handle for manually guiding the cutting grinder, a detection device including at least one sensor for detecting a first cutting position in which the cutting grinder is disposed on a first side of a rail symmetry plane, and for detecting a second cutting position in which the cutting grinder is disposed on a second side of the rail symmetry plane, and a control unit for setting a rotational direction of the drive depending on the first or second cutting position;
- partially cutting through the rail with the cutting grinder, and thereby manually guiding the cutting grinder in the first cutting position on the first side of the symmetry plane of the rail;
- transferring the cutting grinder from the first cutting position to the second cutting position on the second side of the symmetry plane of the rail;
- detecting the cutting position by the detection device;
- and completely cutting through the rail with the cutting grinder, and thereby manually guiding the cutting grinder in the second cutting position on the second side of the symmetry plane of the rail, and reversing the rotational direction of the drive between the first and second cutting positions.
