Cubic boron nitride grinding wheels are mainly used for grinding the cutting edges of paper cutters (sharp steel, carbon steel, high temperature steel) in paper mills. The sharpness of the blades is restored after grinding.
Resin CBN grinding wheel for paper knife is mainly used for resharpening HSS, hardened steel, alloy steel, band saws in tissue paper manufacturing industry, ensuring the continued efficient operation. Otherwise, the passivated blade may has cutting marks, crooked cuts and burrs on the paper during the cutting process.
Features:
CBN grinding wheel has many excellent features of diamond grinding wheel, as well as higher thermal stability and chemical inertness to iron-based metals and their alloys. When grinding stainless steel blades, CBN grinding wheel has wear-resistant, heat-resistant and will not burns to the blades. After sharpening, there is no any broken edges to ensure the sharpness of the blade edge.
Our resin CBN grinding wheel for paper knife is made from first-class and stable raw materials, with senior control system to ensure the high quality of products.

Why Do Paper Need To Resharpen
The blade of the paper cutter is made of the blade and the blade body by high temperature welding. The part of blade edge is usually made of HSS or high hardness chromium tungsten manganese CrWMn steel, some made of tungsten carbide. The blade body is usually made of low carbon steel. After quenching, the hardness of the blade can reach 60-64HRC.
The paper will be cut before putting in storage. Usually the paper cut should not have burrs or broken edges, so the blade must have sharp edge. The paper cutters will be on operation for 24 hours a day, the paper knives will experience varying degrees of wear during long-term operation. Once the cutting edge is not sharp, need to replace a new one. The old one should be taken down for sharpening.
Resharpening the cutting edge of paper knives is usually done on the tool grinder, corundum grinding wheel and CBN grinding wheel is used. With coarse abrasive particles, corundum grinding wheels can have a larger feed rate, making cutting relatively sharp. After resharpening, the blade edges can be magnified, there will be varying degrees of breakage, which affects the quality of paper cutting. CBN grinding wheels are used by more and more people, which obtain smoother and sharper cutting edges.
