Cross cutter is a specialized equipment for corrugated cardboard production line to disconnect the cardboard according to the set length. The knife head is installed on a pair of spiral bevel gears, and the bevel gears rotate to set the cardboard specifications according to the automatic control system to disconnect the cardboard at a set length. So how long does a cross cutter knife head last?

    General cross-cutting machine cutter head edge selection of carbide cutting tools, high temperature resistance, wear resistance, long service life, if all normal conditions, the cutter head service life can reach eight million times. Of course, if the use of improper, will also affect the service life of the cross cutting machine knife.

    The reason why the service life of the knife is so long, and its manufacturing process and the choice of materials is closely related.

    Maoyuan Machinery Company by improving the knife roller (knife cylinder)) production process, enhance the knife roller (knife cylinder) balanced precision, and remove the spiral bevel gear (knife cylinder) deformation. At the same time, the use of higher toughness raw materials, from 45 carbon steel to 42CrMo, and then to the polymer material CFRP carbon fiber material. Carbon fiber material is the density of steel 1/4; is 5 times the compressive strength of steel. It has high toughness, small deformation and low moment of inertia. It is very suitable for knife roller. When laser cutting cardboard, the knife cylinder with the mandrel high-speed operation, in order to reduce the noise, improve the rolling bearing lubrication, add lubricant in the knife cylinder, with internal damping effect, and reasonably reduce the noise when high speed laser cutting.

    Therefore, precision mold manufacturing and processing technology to ensure high toughness, low inertia force and automatic control system organic chemical pairing, all normal application, actual operation of the cross-cutting machine, in order to ensure that the cross-cutting machine cutter head service life for a long time.
