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.).
Jiuli Knives has deep knowledge in the field of slitting circular knives and metal cutting knives and has accumulated a lot of experience in the use of flatness. So, if you have any rotary shear blade demand, please do not hesitate to write a mail to firstname.lastname@example.org or email@example.com .
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.
