It is used for cutting the upper and lower circular knives of the positive and negative plates of lithium-ion batteries for lithium-ion power batteries and 3C industries. From the unique material formulation to the precision edge grinding technology, the slitting burr is better suppressed and the sticking is prevented. This product can provide tungsten-cobalt carbide material (strong versatility), titanium carbonitride-based cermet material (continuously sharp), diamond-like coating material (Ta-C high-efficiency anti-adhesion) and more according to user needs. a choice.
