Measurement of electrical sheets

Another most promising application is the laser cutting of electrical sheets. The iron cores of electrical machines are made of stapled sheet stacks. Segments with narrow tolerances and with highest cutting edge qualities have to be cut out of boards or rolls. The degrading of the magnetic properties in the cutting edges should be as low as possible. The high demands on precision and the thermal sensitivity of electrical sheets require tailored process optimizations and developments.
