A set of Circular Slitter Knives refers to the use of upper and lower circular knives. The size of the slitter knife and materials used in the design of the machine will be varied by the object being cut. The sizes of the circular knife under below are: (118 ~ 80) Ø x 0.8mm SKH9 and (100 ~ 66) Ø x 0.85mm SKH9 .
The production of blades has its expertise. Overcoming the difficulty of its own process and meeting the expectations of its clients has always been the goal of Jiuli Knives. Among them, the flatness has always been an indicator of the knife making process; how to solve the cumulative tolerance problem when multiple blades are placed on the machine at the same time? This is not only the consideration of the machine design, and it is also the proof of blade maker to control all the manufacturing processes.
There is not cumulative tolerance when a single-piece slitting circular knife is using; However, when dozens or hundreds of circular knives are placed on the machine at the same time, adding a few tolerance of each blade will be a huge tolerances. Some industries have extremely stringent tolerance requirements for blades because this not only affects the efficiency of the cutting which also impacts the manufacturing costs (eg, the amount of scraps, etc.).
The design of the circular knife will vary depending on the operation of the machine and the industry. The circular knife described below is used to slit the material at the paper and plastic industries. The actual needs of the customers let us making the knives to meet their requests. That's our daily working life and we are enjoying that.
The rewinder is used in a wide range of applications, such as paper, film, metal foil and other industrial processes. The slitter knife is installed on the winder to cut the raw material, and the cut material is sequentially re-rolled into finished products. Therefore, the blade according to the speed of the winder, the material of the cutting material, etc., will also differ in the process of the blade manufacturing and the choice of materials.
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.
Material: High Speed Steel (HSS), Powder High Speed Steel (PHSS), Solid Steel (D-2) and Tungsten Carbide (TCT).
