Metal slitter blades are very important in the manufacturing process because they are the most critical part of the coil slitting machine knife block. These blades are machined to a very high level of precision and are usually manufactured using ultra-precision flat grinding machines and special grinding methods that are subject to strict quality control. All finished products must be within 0.003mm (max) in thickness and flatness.
There is a close relationship between the quality of the blade and the processing technology, and they are of great significance in shortening the production and processing cycle and reducing the processing cost. When selecting inserts, it is necessary to choose accurately according to the type of material to be slit, slitting speed, slitting direction, feeding speed, slitting width and other specific parameters. These inserts not only affect the ability and performance of cutting processing, but also directly related to the quality of the surface of the work-piece and dimensional accuracy.
1. The application of new blade materials increases. Ceramics, cermet, silicon nitride ceramics, PCBN, PCD and other blade materials to further enhance the toughness, application occasions are increasing.
2. Cemented carbide materials and coatings increased. Fine particles, ultra-fine particles of cemented carbide materials is the direction of development; nano-coatings, gradient structure coatings and new structures, materials, coatings will greatly improve the performance of the tool; physical coating (PVD) applications continue to increase.
3. Rapid development of cutting technology. High-speed cutting, hard cutting, dry cutting continues to develop rapidly, the scope of application is rapidly expanding.
4. The degree of informationization is improved, the cooperation of tool manufacturing enterprises is strengthened, and the competition in the market is intensified.
5. Blade manufacturer role change. From the simple production and supply of cutting tools, expanding to the development of new cutting processes and the development of corresponding complete sets of technology and solutions, to provide users with comprehensive technical support and services.
