A central control unit (9) controls the actuators to move the cutting head (17) in the cutting zone (ZD) along a path determined by the contour of the pieces (2) to be cut and the speed of the material (3).
Device and method for separating a longitudinally-extended cylindrical workpiece
In a device for separating a longitudinally-extended cylindrical workpiece, which has a diameter in the sub-millimeter range, into individual segments, the workpiece is guided in a clamping device. The clamping device includes a first and a second clamping jaw and a feed opening for the workpiece. The feed opening is fitted between the clamping jaws on the side facing the other clamping jaw and a longitudinal groove which defines a direction of advancement of the workpiece for receiving and guiding the workpiece between the clamping jaws. The clamping device has a passage for a laser beam and a cutting gas, which passage defines a working zone, disrupts the longitudinal groove and runs parallel thereto. A cutter head is arranged in the working zone and has an outlet opening for the laser beam and the cutting gas, which outlet opening is aligned with the passage.
