With the rapid growth of the market, the demand for blades has significantly increased. Blades are essential cutting tools used in a wide range of industrial applications, particularly in shearing and slitting operations. The quality of a blade is closely tied to its manufacturing process, making it crucial to optimize both performance and efficiency. Reducing production time and minimizing processing costs have become key priorities for manufacturers.
Most blades come with detailed specifications that directly affect their cutting performance and durability. When selecting a blade, it's important to consider various parameters such as the type of material being cut, cutting speed, direction, feed rate, and slit width. Choosing the right blade based on these factors ensures better results and longer tool life.
Slitting machine blades are widely used in sheet metal, strip, leather, and packaging machinery. They are typically made from high-quality materials like 9CrSi, SKD, SKH, T10, 6CrW2Si, Cr12MoV, LD, H13, and W18Cr4V. These blades undergo a complete vacuum heat treatment process to ensure uniform hardness and precision. The blades must be smooth, flat, and have a sharp, wear-resistant cutting edge, making them ideal for sheet slitting and cutting units.
As the most critical component of the slitter holder, the blade requires extremely high precision. For flat surfaces, super-precision plane grinding machines are used, employing special grinding techniques and strict quality control to maintain thickness and flatness within 0.003mm.
A complete slitting knife set also includes spacers, gaskets, and other components. These parts help maintain the proper spacing between blades and adjust the gap between upper and lower blades. Standard gaskets typically range from 0.8mm to 150mm in thickness, with a hardness above 45 HRC to prevent scratches and ensure durability. Their thickness tolerance is strictly controlled within 0.003mm, and both the inner hole and outer diameter are blackened to enhance rust resistance.
Slitting machine blades are extensively used in industries such as steel manufacturing, pipe production, non-ferrous metal processing, strapping, cold rolling, packaging, steel plate processing, and slitting operations. Their versatility and reliability make them an essential part of modern industrial production.
