slitting knives for Slitter Scorer

Razor Slitter Knives are used often to cut the cardboard sheet into the required size. As the machines types differs, Razor Blades for NC Slitter Scorer are also different in the process of cutting the Corrugated Board; They can be BHS, Marquip, FOSBER, TCY, HEISH HSU, K&H, FULI, MINGWEI. With different Outer Diameters and Inner Diameters, even the location holes on the surface of Razor Slitters.

Razor Slitters used to produce in the common hardened steel. With incrasing requirement, they can not meet the needs. Much Better Performances are used now. They are Tungsten Carbide Materials and High Speed Steel Materials. 

1. Tungsten Carbide/Cemented Carbide;

Sintered tungsten carbide - cobalt cutting tools are very abrasion resistant and can also withstand higher temperatures than standard high-speed steel (HSS) tools. The using time is 25 times longer than the high speed steel knives. 

2. High Speed Steel;

It is a subset of tool steels, commonly used as cutting tool material.HSS to cut faster than high carbon steel, hence the name high-speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above Rockwell hardness 60) and abrasion resistance (generally linked to tungsten and vanadium content often used in HSS) compared with common carbon and tool steels.
