Abstract
The invention relates to a method for sawing a long profile (3) in that a sawing disc (2) having teeth (6) arranged around a circular outer circumference of the sawing disc (2) is rotated freely, the sawing disc (2) is advanced from a freely rotating position to an outer wall of the long profile (3), and a zero tooth (Z1, Z2, Z3, Z4) engages as the first of the teeth (6) in the material of the outer wall, wherein, during the free rotation of the sawing disc (2), lateral runouts (d) of the teeth (6) are determined, and a tooth (6) having a minimum lateral runout (d) is determined and used as the zero tooth (Z1, Z2, Z3, Z4).

Method for sawing a long profile (3) in that a sawing disc (2) having teeth (6) arranged around a circular outer circumference of the sawing disc (2) is rotated freely, the sawing disc (2) is advanced from a freely rotating position to an outer wall of the long profile (3), and a zero tooth (Z1, Z2, Z3, Z4) engages as the first of the teeth (6) in the material of the outer wall, characterised in that during the free rotation of the sawing disc (2), lateral runouts (d) of the teeth (6) are determined, and a tooth (6) having a minimum lateral runout (d) is determined and used as the zero tooth (Z1, Z2, Z3, Z4);
- wherein the lateral runouts (d) of the teeth (6) are continuously measured during the rotation relative to a distance sensor (4) in a fixed position and angular positions (α) of the saw disc (2) are continuously measured, a lateral runout angular position profile of the sawing disc (2) is determined and a tooth (6) with minimal lateral runout (d) is determined from the lateral runout angular position profile.
Machine for cutting sections of a long profile (3) to length, comprising a receptacle for the long profile (3);
- a sawing disc (2) with teeth (6) arranged around a circular outer circumference of the sawing disc (2);
- an advancing direction (V) for the sawing disc (2) in the direction of the receptacle (1), characterised in that, laterally along an axis of rotation alongside the teeth (6) of the sawing disc (2) there is arranged a distance sensor (4), which is directed towards the teeth (6) of the sawing disc (2) and measures lateral runouts (d) of the teeth (6) during the free rotation of the sawing disc (2), and an evaluation unit which is connected to the distance sensor (4) by which measured values from the distance sensor (4) can be supplied to the evaluation unit;
- and an angle measuring device for a rotational position of the sawing disc (2) which is connected to the evaluation unit and by which a lateral runout angular position profile of the sawing disc (2) can be determined and by which a zero tooth (Z1, Z2, Z3, Z4) can be determined.
