The PCB is placed with its pre-scored groove onto the linear blade and the circular blade is then drawn by hand across the PCB. The clearance between the upper guide and the linear blade ist adustable to ensure that the PCB is only separated in the pre-scored groove.
Dial gauge. With the dial gauge mounted on the carriage, the parallelism of the circular and the linear blade is tested. On request the parallelism can be adjusted. This control ensures that the PCB panels always will be clearly separated and correct.
