Several Production Technologies On Diamond Cutting Blades
Diamond saw blade is a very sharp cutting tool, which is widely used in the stone industry. There are many types of diamond saw blades, and the functions of different types of diamond saw blades are also different. The differences in types are mainly due to differences in their production processes. Now HKTools will talk about the production process of diamond saw blades.
According to the process of diamond saw blades, it is mainly divided into three categories:
▶Sintered Diamond Saw Blades;
▶Welded Diamond Saw Blades;
▶Electroplated Diamond Saw Blades;
1.Sintered Diamond Saw Blades
Sintered diamond saw blades are divided into cold-pressed and hot-pressed tablets. Here is the production process of disc sintered diamond saw blades :
▲Fully mix diamond powder and metal powder to make mixed metal powder.
▲Then put the mixed metal powder and alloy matrix into a specific mold for compression molding, In this way we get the preliminary diamond saw blade.
▲After the mold is pressed and formed, the formed diamond saw blade is put into a specific high-temperature sintering furnace. Different factories have different sintering furnaces to meet different requirements according to their needs.
▲After high temperature sintering, the diamond saw blade is initially formed, and then the surface treatment is carried out, the surface of the diamond saw blade is polished, and then the surface of the diamond saw blade is painted, which mainly plays the role of beauty and rust prevention.
▲After the above steps are completed, the qualified products need to be edged. This step is to enable the finished product to be directly applied and give a good terminal experience.
▲After re-inspection, the final product is packaged. Then go to the warehouse and wait for shipment.
It should be mentioned here that the only difference between the cold-pressed diamond saw blade and the hot-pressed diamond saw blade is whether pressure treatment is required during the high-temperature sintering process. This process can improve the quality of diamond particles and metal powder, tightness, improve overall life and stability, therefore, the cost of hot-pressed diamond saw blades is usually higher than that of cold-pressed diamond saw blade. And the normal cutter head is 7mm, 8mm, 10mm, 12mm. You can choose different suitable products according to your needs.
2.Welded Diamond Saw Blades
Welding refers to the melting point below the weldment. After the solder and the weldment are heated to the melting temperature of the solder at the same time, the liquid solder is used to fill the gap of the solid workpiece to connect the metals. During brazing, the oxide film and oil stains on the contact surface of the base metal should be removed first, so that the capillary can play a role after the brazing filler metal is melted and increase the wettability and capillary fluidity of the brazing filler metal. According to the different melting points of the solder, brazing is divided into brazing and soldering.
Welded diamond saw blade are mainly divided into three categories:
▷Vacuum Brazed Diamond Saw Blades;
▷High Frequency Welded Diamond Saw Blades;
▷Laser Welded Diamond Saw Blades;
3.Electroplated Diamond Saw Blades
Electroplated diamond saw blades adhere the saw blade powder to the substrate through electroplating. But starting in 2012, the country gradually canceled the production of electroplated diamond products, mainly due to serious pollution. Therefore, at present, most of the general market is dominated by sintered diamond saw blades, while some industrial and professional markets are dominated by welded saw blades.
From the comprehensive cost point of view, cold-pressed diamond saw blades < hot-pressed diamond saw blades < high-frequency welded diamond saw blades < laser welded diamond saw blades.
