A circular blade is a type of cutting tool that consists of a circular disc with a sharp edge or edges. The circular blade is mounted on a shaft or arbor and rotates at high speed to cut through a variety of materials.
Circular blades are commonly used in a variety of cutting and machining applications, including woodworking, metalworking, and paper processing. In woodworking, circular blades are used in saws such as circular saws and table saws to cut through wood and other types of materials. In metalworking, circular blades are used in machines such as lathes and milling machines to cut and shape metal. In the paper industry, circular blades are used in roll slitting machines to cut wide rolls of paper into narrower rolls or strips.
Circular blades can be made from a variety of materials, including high-speed steel, carbide, and diamond. The choice of material depends on the specific application and the type of material being cut. For example, high-speed steel blades are suitable for cutting through softer materials such as wood, while carbide blades are more suitable for cutting through harder materials such as metal. Diamond blades are used for cutting through extremely hard materials such as ceramics and stone.
Overall, circular blades are a versatile and essential tool in many cutting and machining applications, and are widely used in a variety of industries.
