Principle of Paper Cutter

The principle of a paper cutter is relatively straightforward. The blade is attached to a lever or a hydraulic/pneumatic mechanism (in the case of powered cutters). When the operator activates the cutting mechanism, the blade moves in a downward motion with sufficient force to cut through the material.
The cutting surface provides a stable platform against which the material is held in place. Some paper cutters have clamping mechanisms to ensure that the material doesn't move during the cutting process. The sharpness of the blade and the force applied determine the quality and clean - ness of the cut.
