Tungsten Carbide Slitter Blades / Slitting Knives
What is tungsten carbide slitter blade / Slitting Knives ?
Essentially, it is a slitting blade made using tungsten carbide manufacturing.
Tungsten Carbide is an exceptionally durable and tough material, featuring high hardness, wear resistance, flexural strength, and corrosion resistance. A special polishing process is employed to mirror-polish the cutting edge, which helps to minimize friction between the tool and the processed product. It is an essential tool for slitting machines.
Tungsten Carbide slitter blade grade selection
Due to the diverse materials that require slitting, we have formulated a range of carbide grades that are suited to specific material types and applications.

Analysis Of Typical
Problems Of Corrugated Board Slitting Blade
A. The hardness of the blade and corrugated board might not match.
A. Unstable swing grinding wheels may cause this problem, even break the blades.
B. A collision with hard objects may cause the chips on the cutting edge.
A. incorrect assembly e.g. deformed flange plate; wrong screwing will cause the breakage of blades.
B. Unstable swing grinding wheels break the blades; please check the bearing of the grinding wheels.
C. The problem may be caused by collision with other hard objects.
A. Please check the cutting edge of your blade. Is the cutting-edge sharp enough?
B. The corrugated board is too wet.
A. Is the grain size of the grinding wheel adequate?
Too coarse a grain size of grinding wheel shortens the lifespan/performance time of blades.
B. Excessive grinding: the grinding interval is too short or the grinding pressure is too high.
