The slitting machine realizes the purpose of slitting by means of blades, so the work of optimizing the slitting machine should start from improving the use method of blades, then how to do it? Let's analyze it. For slitting machine, its blade selection is very critical. Now there are more and more slitting machine blades in the market. At the same time, they are developing towards more accurate size and high wear-resistant hardness, which is a favorable guarantee for improving work efficiency. Different working conditions also put forward different requirements for Slitter cutters. For example, high-speed assembly line processing needs high-quality ultra-thin cutters, so we need to improve the traditional cutters and develop products that meet the requirements as soon as possible. In the aspect of using method, we should also treat it correctly. In order to improve the using skill of the cutter, we should replace the blade of the slitter with a new one and operate it in small batch first, so as to determine the balance and processing speed of the blade and ensure the normal operation. After years of development, the slitter equipment and cutting tools have been greatly improved, so as to increase more profits for the enterprise.
