In the process of blade processing of precision slitting machine, the high-precision of the cutter cooperates with the high-speed slitting machine to form a fast processing channel, which brings a very fast production speed to the enterprise. It's all about relative processing speed. Only when equipped with tools with good precision and finish can we obtain uniform speed. The precision of machine tools, tools and fixtures is very important. At present, the fixture error value of the fixed tool is within 0.03mm, while the error value of the tool is required to be higher, so that the processed material can be processed quickly under a certain slitting pressure, surface burr and other bad effects.
In order to obtain a higher level of accuracy for the blade of the slitter, it is very important to master the grinding process, and the choice of abrasive should be a semi-solid grinding wheel with viscoelasticity, softness and cutting. Different viscosity, grinding type and abrasive particle size can also produce different finish effects. At present, the commonly used blade grinding wheels of slitting machine are mainly silicon carbide, cubic boron nitride and alumina. These wheels can be used for uniform grinding of the surface and of the tool, producing very little grinding heat, avoiding the deformation and annealing of the tool caused by too high grinding temperature, so as to ensure the quality of the tool and the processing speed.
In order to complete the grinding of slitter blade more smoothly and obtain the best finish effect, the enterprise summarizes many factors affecting the quality of cutting tools according to the experience of other enterprises. In addition to the reasons for the equipment, the enterprise also trained a group of experienced operators and designed suitable grinding fixtures to achieve the purpose of fine grinding and ensure the machining accuracy, stability and sharpness of slitter blade. At present, in view of the increasing application scope of slitting machine, all kinds of light industry, packaging, decoration and other industries are inseparable from slitting machine and cutting tools. In order to make the market of cutting tool industry larger and larger, it will become another bright spot of industry development.
