Classification Round knife into flat round knife, circular knife tooth, front steel circular knives, circular knives and other alloys. Large circular blade, large circular knives, circular knives, circular knives, small round cutter, generally circular blade diameter: ∮300-1000mm, thickness 0.5 -300mm; folding machine round knife, front steel circular cutter knife, Jin Shi watt circular blade, circular slitter knife, cut the sword blade, carbide cutting round knife, cut the carton dashed round knives, dashed circular blade, circular cutter knife, splintered machine round knife cut rubber round knife, cut the leather with a round cutter, slitting blades, tungsten steel circular blade, alloy blades, circular blade alloy and so on. Cutting blade is mainly used for cutting paper, film, gold, silver foil, aluminum foil, copper foil, tape and other items, requiring a minimum blade cut resistance, abrasion resistance maximum. Out of merchandise and cutting accuracy requirements sometimes required to achieve micron-level precision blade selection Cr12mov, w6mo5cr4v2, w18cr4vSKH, M2, Germany, 1.3343, 1.2888, etc. Germany. On the information industry in terms of use of the tape, realistic reproduction of sound and images is an absolute condition. In the manufacturing process, slitters, determines the accuracy of the tool fixture tape incision accuracy, it can decide whether to permit playback of sound and image full of presence. Cutting blade: slitting blades down and wider use of paper, paper products processing, adhesive tape products, film, wire and cable, rubber, aluminum, chemical fiber, non-manufacturing cloth, composite packaging materials, telecommunications and electronics, tobacco, leather, printing food and clothing industries. Circular blade circular blade circular blade that is mainly used for cutting pastry, paper, film, gold, silver, aluminum, copper and other items, requiring a minimum blade cut resistance, abrasion resistance maximum. Circular blade products are widely used in ceramics, printing machinery, paper industry, cardboard boxes, forestry, rubber, plastics, food machinery, textile, electrical appliances, light industrial machinery, aluminum foil, metallized film, tobacco, cigarette machinery, packaging materials, films, electronic appliances, wires, cables, shipbuilding, chemical, glass, textiles, feed, paper tubes, forestry, woodworking machinery, plastic crusher, side seal, the seal machinery, bottom seal bag making machine, wood processing, food packaging, paper and aluminum foil cutting, electrical and mechanical metallurgy, medicine, rubber and other industries. Shanghai letter a cutting blade production process ---- choice of materials according to customer requirements. 2 ---- forged forged mainly to improve the density of the material. 3 ---- annealing temperature was decreased to processing. 4 finishing ---- mainly to material molding process. 5 ---- test whether the product is consistent with the test sample drawings. 6 hardening ---- improve molding products and materials appropriate hardness. 7 ---- annealing in order to increase the wear resistance of the product must be annealed incubation time. 8 quenched ---- mainly tune parallelism quality products for processing. 9 ---- coarse surface of the product to each kibble shape. 10 grinding ---- ultra-fine grinding, mirror grinding, to improve the accuracy of the product, parallelism. 11 test ---- refused to let unqualified products into the market. Packing ---- 12 different products according to different packaging.
