Tungsten carbide circular slitting blade for lithium battery industry
Production Introduction
The new energy series alloy lithium battery electrode continuous slitting knife is made of cemented carbide powder by pressing and sintering, which has the characteristics of high hardness, strong wear resistance, anti sticking knife and so on. It specializes in solving all kinds of bad phenomena such as sticking knife, dust, burr, knife back print, wavy edge, color difference and so on. The full inspection blade is enlarged by 500 times without notch. During the slitting process of the positive and negative plates of lithium battery blade, the edge collapse and burr caused by the poor quality of the slitting edge will cause the battery short circuit problem and form a serious safety hazard. Chengdu Kedel Tools Co., Ltd. has many years of experience in the production of cemented carbide industrial tools. All alloy blanks are produced by ourself, and has a deep understanding of the grinding and processing of alloy tools. Adhering to the spirit of "craftsman", strictly control the dimensional tolerance of the blade. The unique cutting edge precision processing technology and 100% cutting edge automatic equipment full inspection process ensure the excellent performance of the lithium battery pole slice slitter.
Product Features
1. Hard alloy tungsten steel material, with strong wear resistance;
2. The cutting edge has high machining accuracy, and the thickness accuracy can reach 3 microns;
3. Long service life, less tool change, high cost performance, cutting length up to 20000 meters;
4. The outer circle of the blade has good consistency, the blade edge is strictly enlarged, and there is no curling during detection, and the burr is small;
5. It is mainly used for cutting non-ferrous metals such as lithium battery pole piece, ceramic diaphragm, copper foil, aluminum foil, etc;
6.The blades are divided into upper knife group and lower knife group, which are used in complete sets.
