The plastic shredder blade is an important part of the shredder. If it is worn or blunt, it must be ground or replaced in time. After the shredder cutter is blunt, it will affect the shredding effect of the entire equipment. It is necessary to perform timely inspection and maintenance, and to perform inspection and maintenance of the shredder blade in normal times.
The grinding of the grinder cutter is not the same as the grinding of other cutters. Other types of mechanical blades basically use a grinder to grind the plane or the edge part. The speciality of the structure of the grinder cutter is multi-claw The design of the blade makes it impossible for the grinder to grind it, and the single flat grinding of the blades will cause the gap between the blades to be too large and seriously affect the use.
Then how to sharpen the cutter of the shredder? We must first understand that the wear of the shredder blade is mainly the wear on the knife claws, and the easiest way to grind is to polish the inside of the blade edge with a polishing machine until the blade edge is sharp. It must be noted that it must be planed along the arc of the knife claw, and must be perpendicular to the plane of the shredder blade, so that the loss of the original knife body will be minimal.
