POSTPRESS:The sharpest knife in the drawer

A high-speed cutter must be able to perform precise and clean cuts not only with paper, but also with hard materials such as board, plastic, laminates, etc. One of the keys to assuring optimum performance for a POLAR cutter is taking proper care of its all-important cutting tool: the knife.

Until it is ready to be installed, the knife should always be carefully kept in its special box for safety and to protect its cutting edge from damage. When a knife is to be replaced, it must never be placed on the machine table without a cardboard or a wooden support underneath. The surfaces of both the knife and the knife bar must be completely free from burrs and dirt. The threaded fixing holes in the knife and the knife screws that ensure firm and precise seating should be kept in perfect condition.
