A robot served automatic cross-cutting machine with two circular saw blades with diameter 400 mm, symmetric adjustable 200-1250 mm. Through linear sawing 10 work pieces (T=10,8 mm) are cross-cut at the time, stacked on each other with widths from 68 to 105 mm. Work pieces are fed from pallet trough gripper and robot, to a straightening device and after that to the crosscut saw.
