Definition and Initial Formation of Diamond Circular Saw Blade

Diamond saw blade refers the blade whose diamond cutting edge is located in the inner-circle or on the outer circumference of the blade. For example, the diamond of stone cutting saw blade is located in the edge of the outer periphery of the substrate; Commonly used circular cutting saw blades that are used for cutting semiconductor wafer, whose diamond is located on the edge of the circle.

Circular saw blade is a kind of commonly used cutting tools and has big span in the diameter from a few millimeters carved piece to a few meters big saw blade; The cutting object is numerous, and the object's structure, hardness and size have much difference. Therefore, the raw materials, the processing and manufacturing methods and the using requirements are different.

The application of diamond saw blade has a long history. The world's first piece of circular saw blade inlaid with diamond reaches 2m in diameter, which was made by the French Jaeguin in 1885. It is made from 0.8 carats of rough diamond, firstly made into sawtooth and to set it in the surrounding of dovetail matrix by hand, then fixed with rivets. This kind of method for the production of saw blade has been used for almost forty years. After 1930s, with the powder metallurgy method gradually mature, people gradually begin to make the fan blade with metal powder metallurgy, and weld the sawtooth on the steel substrate by using the method of welding, which is now known as early form of welding circular saw blade.

In the 1960s, the manufacturing technology of circular saw blade obtained the rapid development. of Circular saw blade appeared that is suitable for all kinds of cutting object, different binder categories, and different cutting methods. Now all kinds of manufacturing process methods of saw blades have been perfect, and in most countries, it has formed a complete products supply market about the saw blade.
