High-precision tungsten carbide slitting knives are key products specially developed and produced by the battery industry for higher requirements for incisions. They have good wear resistance and high processing accuracy. Tool outer circle precision is high, and the cutting edge is strictly enlarged and tested. Service life is long. It is an ideal tool for users in the battery industry to reduce cutting costs and improve cutting quality.
In the pole piece slitting process, the lateral pressure and overlap of the cutter are the main adjustment parameters of the disc cutter section, which need to be adjusted in detail according to the nature and thickness of the pole piece. In the past equipment manufacturing and technology, the adjustment of the knife often lacks accurate numerical parameters but is based on experience to make corresponding adjustments according to the batch of pole pieces. With the advancement of equipment technology, tool adjustment technology has also been continuously improved and digitized. Nowadays, a pole piece slitting machine tool lateral pressure cylinder automatic adjustment device appears. During pole piece slitting, the side pressure of the cutter is adjusted by setting the cylinder pressure to control the cutting quality.
