SONDERMASCHINEN Automatic Core Drill Laser Welding Machine BSM 300 Dr. Fritsch Sondermaschinen GmbH, 70736 Fellbach, Germany

MAIN FEATRURES • High productivity Fast segment feeding by double gripper system. Welding unit with mirror optics driven on three axes („flying“ optics). Automatic segment feeding by means of a belt magazine. Rotating axis of the tube clamping system with freely programmable division of the core drill tubes. • High and constant quality of the core drill A measuring sensor determines the radial run-out of the core drill tube. The result is the automatic correction of the segment side clearance. The welding seam correction is ensured with the axial run-out measurement on the core drill tube....
