The cutting direction of general industrial tools is nothing more than horizontal or vertical. The circular knife is widely used in longitudinal cutting in various industrial sectors and it's called slitter knife and rotary knife also. The strips of the corrugated paper industry to the strips of plastic or metal sheets are all operated using circular knives. Even the printed circuit board (PCB) industry is inseparable to using circular knives.
The tungsten carbide blade of Jiuli Knives which can base on the client's demand to produce mirror-finished. The circular knife (Slitter knife) has a mirror-like surface after the treatment which can reduce the flying debris of the cutting object and improve the quality of the object to be cut. Combining a circular knife (Slitter knife) with a pneumatic tool holder can effectively improve the efficiency of blades change.
Because each field will use the circular knife (Slitter knife) to do the slitting. The size of the blade and the raw materials selected vary depending on the hardness of the object being cut. The commonly materials using are SK5、HSS、PHSS、SUS4407、SUS420J2、SKD11、52100 and tungsten carbide, etc.
The principle of the crusher blade is to use a set of running knives to smash the target (pulverized material). When the target (pulverized material) is broken by the crusher blade, the blade is gradually worn out.
There are many applications at different industries which are using crusher knives . Therefore, Jiuli Knives will base on the client's application to select the right material to produce the crusher blade, and it will influence the wear resistance and toughness of the crusher knife to be optimized, the product life of the blade to be increased, the pulverizing ability to be maximized and the thickness of the pulverized powder is uniform.
How to provide a set of sharp and hard with durable tools for the clients requires professional judgment. The crusher knife is commonly used in wood and plastic recycling industries, which should be chosen A8, SKD, HSS-inlay and tungsten carbide steel inlay raw material.
