The carbide circular knife is widely used for slitting paper, plastic films, cloth, foam, rubber, copper foils, aluminum foils, graphite, etc. This kind of knife is ground by professional equipment. Its nice appearance, high precision, and durable life make it has high-cost performance. Hoose high-quality raw materials . Rough forming - Vacuum heat treatment -Cooling and tempering -Testing hardness -Finish grinding size -Product testing -Anti-rust spray Marking - Packaging.
The paper cutter blade is one of the important parts of the paper cutter, which is widely used in the papermaking and printing industry. Paper cutter blades are used in papermaking, printing and other industries. The sharpness and service life of the blades greatly affect the working efficiency of the paper cutter.
Our tungsten carbide circuit board cutter blades are suitable for Accuscore, Anita, Avalon, Filotec, Loehr&Herrmann and Telmec, Banaby and Mania-testerion(JWA) machine.

This blade with very high precision requirement, the material must be the original raw material sub-micron tungsten carbide grains, cutting edge generally 200-500 times magnification detection required without gaps.
Large surface grinding technology to achieve the mirror effect finish Ra less than 0.02. Sharp cutting edge without burrs, cutting force to ensure battery pole piece product quality.
Cutting edge types: Single or double side available
Tungsten carbide grade:The components of tungsten carbide are WC(hard phase) and cobalt (binder phase).The physical properties of alloy depend on the grain size of WC and the percentage of hard phase,we have dozens of material grades for your different applications.
