At present, the crosscutting machine is mainly used for leather, paper, plastic film, rubber, PP, PVC, copper foil, aluminum foil and other materials. The blade quality directly determines the efficiency of the crosscutting machine. If you want to do something well, you must first use its tools!
Crosscutting machine blade is used in crosscutting machine. As for the crosscutting machine, it is one of the important stand-alone machines in cardboard production line. Crosscutting machine is divided into mechanical crosscutting because of different transmission control modes.
Cross cutting machine blade picture machine and computer controlled cross cutting machine. The computer crosscutting machine is controlled by industrial control computer. According to the set length, the cutter shaft is controlled to run and cut off the cardboard. With the precise transmission of the mechanical part, the paper cutting error can be controlled within (+1 mm). Computer controlled crosscutting machine has helical cutter and straight cutter. Spiral cutter is more suitable for high-speed cardboard cutting, and paper cutting is smooth, blade life is long, blade should use high-speed steel.
At present, there are two kinds of cutter blades in our country, the integral cutter and the mosaic cutter.
The whole cross-cutting knife is made of SKD11, CR12, 9CRSI and other materials. The knife edge is ground by heat treatment. HRC50-58 degrees. The material is different from the hardness. The service life of this kind of knife blade is generally not high, the knife edge sharpness is not enough, and the effect of cutting some high-precision materials is not good.
Mosaic cross-cutting tool refers to the cutting edge mosaic HSS, tool body using abrasive steel SKD11, heat treatment grinding out the cutting edge using, HRC60-63 degrees, different high-speed steel HRC is different, this kind of blade generally has a high service life, everyone knows that high-speed steel has high hardness and toughness, suitable for high-speed cutting, even if cutting some high-precision materials are swimming. Excellent edge, smooth and burr-free incision, long-term durability.
