Slitting Blades 


Circular Slitter Blades are the most important part of cutting tools. Because of the requirement for the accuracy of the product, the Circular Slitter Blades require high accuracy and must have micron-level accuracy. In the manufacturing process, the accuracy of the slitting machine blades determines the accuracy of the product cut and the quality of the product.

For the flatness, Jingfeng Knife Manufacturer use ultra-precision flat grinding machine, with a special grinding method, and strictly quality controlling, ensure that all finished Circular Slitter Blades with thickness tolerance, parallelism tolerance achieve to 0.005mm (max) or less.

The Circular Slitter Blades are made of high-quality tool steel and high-alloy die steel and is suitable for slitting operating and various types of slitting machine. A good slitting machine requires that the slitting machine blades have the smallest cutting resistance, the highest wear resistance, and the sharp and durable cutting edge. 

As the top 5 professional slitting blade manufacturer, Jingfeng Knife Manufacturer's Circular Slitter Blades are designed for high performance and precision cutting processes in various including film and foil, medical, converting or assembling of electronic components.

The Circular Slitter Blades are made of high-quality cutting tool steel D2, SKD, HSS, and Tungsten Carbide. After a perfect vacuum heat treatment processing, making slitting machine blades' hardness uniform and making slitting machines have a precision machining system.


D2 Steel Circular Slitter Blades

D2 steel is the most commonly used material for the top and bottom slitting machine blades. D2 steel Circular Slitter Blades have a long wear life and are easy to sharpen. It is also a versatile material for cutting and slitting applications involving plastics and paper. From wear and low budget perspective, D2 steel’s slitting machine blades are often the most cost-effective option.


 Cemented Carbide Circular Slitter Blades

In environments that require a 24-hour uninterrupted operation, carbide slitting machine blades are ideal for bottom blades. Cemented carbide Circular Slitter Blades maintains sharpness by cutting long coils of abrasive. Mounting inserts are made of D2 steel, while cemented carbide is only mounted at the point of the compression to provide the greatest benefit while minimizing costs.
