Tungsten Carbide Slitter Blades / Slitting Knives
What is a tungsten carbide slitter blade / slitting knife?
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.
Please refer to the table displayed below for more information.

Analysis Of Typical
Problems Of Corrugated Board Slitting Blade
A. The hardness of the blade and corrugated board might not match.
A. …may cause this problem and may even break the blades.
B. A collision with hard objects may cause the chips on the cutting edge.
A. Incorrect assembly — e.g., a deformed flange plate or improper tightening — can break the blades.
B. Unstable swing grinding wheels break the blades; please check the bearings 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?
A grinding wheel with too coarse a grain size shortens blade life.
B. Excessive grinding: the grinding interval is too short or the grinding pressure is too high.
