Introduction of circular knife

The circular slitter blade is a circular slitter blade, which is mainly used for cutting cakes, paper, film, gold, silver foil, aluminum foil, copper foil and other items. The blade is required to have the minimum cutting resistance and the maximum wear resistance. circular slitter blade products are widely used in various industries. This article will briefly introduce the circular knife.

Characteristics of circular knives

The circular knife has high hardness and medium wear resistance. When grinding, its disadvantage is that it has high viscosity and rapid temperature rise. It is recommended to use chromium corundum or microcrystalline corundum grinding wheel for grinding. The annealing temperature of 440C is very low. The hardness of tools and bearings can usually reach hrc57-59. If cryogenic treatment is carried out, the hardness can reach hrc59-61. It is used to make blades with strong corrosion resistance and toughness. Now it is more widely used in hand-made knives and high-quality factory-made knives.

Hardware blade enterprises often use 440c# stainless steel to make circular slitter blades. The carbon content of 440C stainless steel is c-1.2%. This kind of steel has good rust resistance. It is the stainless steel commonly used for imported mass production knives. Its chromium content is as high as 16-18%. It is also one of the first stainless steel used to make circular slitter blades for food, which is very popular.

If heat treatment is carried out as stainless bearing steel, it is generally recommended to carry out cryogenic treatment before tempering operation. Such cryogenic treatment improves the hardness, wear resistance and dimensional stability of the steel. Therefore, the cryogenic treatment of 440C is often used for tool heat treatment.

Round knives are divided into flat round knives, tooth-shaped round knives, steel edge round knives, alloy round knives, etc. Large circular slitter blade, large circular slitter blade, circular slitter blade, circular slitter blade, small circular slitter blade, diameter of general circular slitter blade: ∮ 300-1000mm, thickness 0.5-300mm; Folding machine circular knife, steel cutting machine circular knife, stone brocade tile circular knife, slitting machine circular knife, slitting upper knife and lower knife, carbide slitting circular knife, carton dotted line slitting circular knife, dotted line circular knife, paper cutter circular knife, powder machine circular knife, rubber circular knife, leather circular knife, etc.

Application of circular knives

The circular slitter blade is mainly used for slitting paper, film, gold, silver foil, aluminum foil, copper foil, tape and other articles. The blade is required to have the minimum cutting resistance and the maximum wear resistance. In order to meet the requirements of commodity accuracy, the blade must reach micron accuracy.

circular slitter blade products are widely used in ceramics, printing machinery, paper industry, carton, forestry, rubber, plastics, food machinery, light textile, electrical appliances, light industrial machinery, aluminum foil, metalized film, tobacco, cigarette machinery, packaging materials, film, electronic appliances, wires, cables, shipbuilding, chemical fiber, glass fiber, textile, feed, paper pipe, forestry, woodworking machinery, plastic crushing Edge sealing, middle sealing machinery, bottom sealing bag making machine, wood processing, food packaging, papermaking aluminum foil cutting, metallurgical Electromechanical, medicinal materials, rubber and other industries.
