As we all know, shredders mainly rely on internal blades for shredding operations, which means that their blades belong to wearing parts. If the blunt blade of the shredder is not replaced in time, the shredded material particles will be uneven, which will affect the use effect. However, some customers feel that it is a pity to replace such a new and thick blade.
Today, I will introduce you how to repair the sharpening blade so that it can be used again.
The grinding of shredder blades is different from other blades. Other types of mechanical blades basically use a grinder to grind the plane or cutting edge. However, the cutter structure of the shredder is special, and the design of multi-claw blades makes it impossible for the grinder to grind it. If only the plane of a single blade is grinded, the gap between blades will be too large, which will seriously affect the use. We believe that the wear of the blade is mainly concentrated on the claw, and the simple and effective grinding method is to use a polishing machine to polish the inner side of the cutting edge until the cutting edge becomes sharp. In the process of grinding, it is necessary to polish along the arc of the blade and keep it perpendicular to the plane, so as to minimize the loss of the original blade.
