Customised Cemented Carbide Components Producer And Exporter
With the development of microelectronics technology development, miniaturized devices are increasing day by day, which puts high demands on power supplies. Lithium batteries have become an indispensable part of digital products. The electrode sheet is one of the core components of the lithium battery. The electrode sheet is generally cut from metal foil, copper foil. Tungsten steel lithium battery blades used in lithium battery manufacturing industry, the positive and negative pole of lithium battery slitting process, racked in pole pieces of the unit.
The cutting process of aluminum foil should be very precise, because any burr on the aluminum foil may cause a short circuit of the lithium battery. And to achieve such precise cutting requires sharp and wear-resistant tungsten carbide battery knives.

This blade with very high precision requirement, the material must be the original raw material sub-micron tungsten carbide grains, cutting edge generally 200-500 times magnification detection required without gaps.
Large surface grinding technology to achieve the mirror effect finish Ra less than 0.02. Sharp cutting edge without burrs, cutting force to ensure battery pole piece product quality.
Product Advantage:
1. The battery knife has perfect roundness and smooth mirror surface, each blade is strictly and accurately polished to ensure the best cutting effect, smooth without any burrs.
2. High precision and excellent abrasion resistance.
3. Super Mirror finish to protect the blades from glue adhesion.
4. Reliable performance (less machine downtime)
