Tungsten Carbide Circular Slitting Knife HRC92-95 for Lithium Battery
Tungsten carbide circular slitting blade for lithium battery industry. Lithium battery pole piece slitting knife is a high-precision tungsten steel slitting circular knife used in the battery industry. This series of products are professional cutting tools used in the battery industry with good wear resistance and high processing precision.
The outer circle of the knife has high precision, and the blade has been strictly enlarged and tested. The tool needs less replacement, long service life, and high cost performance. It is an ideal tool for battery industry users to reduce cutting costs and improve cutting quality.
The new energy series alloy lithium battery electrode continuous cutting knife is made of hard alloy powder by pressing and sintering. It has the characteristics of high hardness, strong wear resistance, and anti-sticking knife. The full inspection blade is magnified 500 times without gaps.
During the slitting process of the positive and negative plates of the lithium battery blade, the edge collapse and burrs caused by the poor quality of the slitting edge will cause the short circuit of the battery and form a serious safety hazard. We have many years of experience in producing carbide industrial tools. All alloy blanks are produced by ourselves and have in-depth knowledge of alloy tool grinding and machining.
Adhering to the "artisan spirit", the dimensional tolerances of the blades are strictly controlled. 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 piece cutting machine.
- Hard alloy tungsten steel material, with strong wear resistance
- The cutting edge has high machining accuracy, and the thickness accuracy can reach 3 microns
- Long service life, less tool change, high cost performance, cutting length up to 20000 meters
- 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
- It is mainly used for cutting non-ferrous metals such as lithium battery pole piece, ceramic diaphragm, copper foil, aluminum foil, etc
- The blades are divided into upper knife group and lower knife group, which are used in complete sets
