The slitting machine blade is the most important part of the slitting tool holder, and its processing precision is even more demanding. For the flat surface, it is necessary to use an ultra-precision surface grinding machine, which is ground by a special grinding method, and is subject to strict quality control to ensure that the thickness and flatness of all finished products are within 0.003mm (max).
Slitting machine blades are mainly used for slitting metal, film, paper, cigarettes, leather, printing, etc.
With the rapid development of the market, the blade industry has higher and higher requirements for blades, which are the most commonly used cutting tools for slitting, cutting, and its quality is closely related to processing technology. Important meaning, most of the detailed parameters of the blade, these parameters determine the processing ability and cutting performance of the tool. When selecting each blade, it is necessary to make an accurate selection according to the specific parameters such as the type of material to be cut, the cutting speed, the cutting direction, the feeding speed, and the cutting width.
The slitting machine blade is mainly used in the slitting production line of metal sheet, strip, leather, and packaging machinery. It uses stable high-speed cutting tool steel 9CrSi, SKD, SKH, T10, 6CrW2Si, Cr12MoV, LD, H13, W18Cr4V and other materials. After a complete set of vacuum heat treatment process, the hardness is uniform, and it is made by precision machining. The cutting edge of the blade is required to be smooth and flat, and the cutting edge is sharp and wear-resistant. Mainly used for sheet slitting and slitting and various slitting units.
In a complete slitting knife set, spacers, spacers and other parts are also included. Its main purpose is to maintain a certain width between the circular blades and to adjust the horizontal gap between the upper and lower blades. The thickness of the commonly used gaskets is between 0.8mm-150mm. Its hardness is above HRC45 degrees regardless of its thickness, which prevents scratches and bruises, and its shape is strong and durable. The thickness tolerance is also required to be within 0.003mm. The inner hole and the outer surface are blackened to effectively improve the antirust performance.
