Diamond saw blade production process
1. Segment production
1). Ingredients: The production technicians of the Super Cutting Diamond Tool company will adjust the product formula suitable for the customer according to the customer's needs, which are diamond powder, metal powder, bonding agent and other materials, and weigh them according to the appropriate ratio.
2). Mixing: The weighed materials are fully stirred and mixed by the fully automatic 3D blender, so that the material powder is completely mixed. Generally speaking, the materials after mixing are evenly distributed to ensure the stability of the quality of the segment.
3). Cold pressing: Our company adopts fully automatic CNC cold press, high-precision steel molds, and presses the agglomeration of the segment through high pressure to ensure the precise size of the cold-pressed segment and ensure the excellent cutting effect. At the same time that the cold pressing tool head is agglomerated, the non-working layer must be processed.
4). Hot pressing: Super Cut Tool company is equipped with 30 automatic sintering machine. The high-quality sintering machine ensures that the segment has accurate temperature and pressure during the sintering process. In the process of heating and pressurizing, the metal powder of the segment undergoes physical and chemical changes, especially the metal powder, the bonding agent, through high temperature, the metal melts and combines to form a harder metal block. After the segment is cooled, the metal block tightly and powerfully wraps the diamond particles, so that the segment has better cutting performance and holding power.
5). Cooling and grinding: After cooling, take out the diamond segment from graphite mold, start to polish the corners and surface to remove burrs, and make the segment look smooth and beautiful.
2. blade body selection process
At present, most saw blade manufacturers in China choose domestic blade body, mainly high-speed steel, alloy steel and other steel materials. Among them, anti-rust treatment, the rigidity, elasticity, weight, size, etc. are required to test to select a better blade body material.
Saw blade welding, opening and packaging
1). Welding: At present, Super Cut Tool company uses two welding machines, high-frequency welding and laser welding to weld the segment. Generally speaking, high-frequency welding is more efficient, and welding is carried out by welding glue and solder. This welding method is widely use because it is cheap. However, laser welding uses local heating and combines the base body and the segment itself. This welding method has extremely high firmness, and there will be no loss of the segment in the later period, thereby increasing the use efficiency and life of the segment. Laser welding saw blades are prone to deform the blade body, so this welding method is generally not used for large diameter saw blades.
2). Opening: At present, Super Cut Tool company has more than 20 units opening grinders and 5 units belt grinding machines, which can quickly complete segment opening. After the opening, the diamond powder of the segment is completely exposed on the surface. It can be used directly for cutting.
3). Packaging: Super Cut Tool company will perform anti-rust treatment on the medium-diameter saw blade, including electroplating solution, anti-rust paint, packaging, using plastic bag as inner packaging, outer packaging as carton packaging, and finally in a group of multiple pieces of wood box packaging can also be packaged according to customer requirements.
Testing and inspection
Super Cut Tool company adopts strict raw material testing, and conducts quality control tests through single crystal three-dimensional structure, purity, strength, and purity of metal powder. In the manufacturing process of the segment, each price process of the segment is weighed, size measurement, hardness test, wear resistance test, etc., through the test, the product quality is more stable. Finally, the saw blade must be tested and inspected for welding strength and impact resistance.
