The correct use and wear of slotting blade for carton printing slotting machine

Carton printing slotting machine, molding machine, as well as a variety of printing die-cutting slot and other multi-functional joint machine. Slotting knife is a necessary tool, its service life directly affects the quality and cost of the carton slotting, quality management and cost management is one of the problems that need to be improved. When the tool wear is related to the cutting knife, the cutting edge of the cutting board is affected by the relative friction. The high content of 5%~l0% sand containing many cardboard, sand relative to the edge grinding effect produced Wei strong, so that the edge surface of the metal has plastic deformation and fatigue wear off. The service life of the cutting tool is decreased with the increase of service time and the sand content of the cutting board (quartz sand, etc.).

Some similar problems of carton printing slotting machine: one is slotting knife (knife) can only be used once, short service life; two is the knife with poor effect, grooving quality instability; three is the resistance of the cutting edge is poor, some local edge crack phenomenon; four is frequently added a new knife, spending large, high production cost. The way to improve the life of some objective factors mentioned in this article are very difficult to avoid or due to accidental injuries and affect the service life of the tool, this is no longer about. Through the subjective efforts, we can solve the problem of the old knife reuse and the selection of the new knife. www.chinacartonmachine.com

In today's price to the quality as the core of the fierce competition in the market, this problem is more and more concerned about enterprise leadership, promote enterprise innovation potential, efficiency savings, connotative development road.

The general quality of slotting tool wear with cutting edge and gradually reduced, will produce burr, burr, fragmentation and waste joint phenomenon. When the product does not meet the standard, you need to replace the slotting knife. Although there are some differences in the service life of imported and domestic slotting cutters
