Diamond circular saw blades are widely used to cut hard materials such as concrete, bricks, and stones. The production process of diamond saw blades mainly involves three steps: diamond segment production, welding, and trimming.
The first step is diamond segment production. The diamond segments are the cutting part of the saw blade. The raw material for diamond segment production is metal powder, synthetic diamond, and metal bond. First, the metal powder is mixed with synthetic diamonds and metal bond in a certain proportion to form a diamond segment mixture. Then, the diamond segment mixture is pressed into a mold, and heated and cured under high pressure and high temperature to form the diamond segment.
The second step is welding. The diamond segments are welded onto the metal base of the saw blade. There are two main methods of welding: laser welding and brazing. Laser welding is a high-precision and efficient welding method, while brazing is a low-cost and widely used method. During the welding process, the temperature and pressure must be controlled to ensure that the diamond segment is firmly welded to the metal base.
The third step is trimming. After the welding process, the saw blade needs to be trimmed to ensure that the diamond segments are evenly distributed on the metal base. The trimming process involves grinding the saw blade edge to a specified diameter and thickness.
In conclusion, the production of diamond circular saw blades involves a complex process of diamond segment production, welding, and trimming. The quality of the saw blade depends on the raw materials, the welding process, and the trimming process. A high-quality diamond saw blade can improve work efficiency, reduce costs, and ensure safety.
