Diamond and Metal Power Selection.

The performance and quality of diamond tools depend on the chosen diamond and metal powders. Recommendations:

Diamond Powder. 

Particle Size: Determines efficiency and surface quality. Finer for precision, coarser for speed.Quality: High-quality powder has uniform crystals and fewer impurities.Binding Strength: Influences wear resistance and tool lifespan. Appropriate binding ensures stable performance.

Metal Powder:

Type: Nickel, cobalt, iron, copper, etc., affect tool performance.Bonding Force: Moderate bonding force is crucial for proper performance.Sintering Temperature: Should match diamond characteristics to avoid damage.Consider tool use, material, conditions, and quality. Manufacturers adjust formulations for top tool performance.

Production Process Selection
2-3-1 (2)
Laser welding is a precise, low-heat welding process, reducing heat stress on diamond particles and tool matrix for longer tool life. It offers high production efficiency and fine performance control through parameter adjustments. 105mm to 1800mm diameter.
2-4-1 (2)
The high-frequency welding process, primarily employed for welding metal materials, enables high-precision welding and yields exceptionally robust weld points. It demands relatively low equipment requirements and is cost-effective.
2-5-1 (2)
Sintering is a process in which diamond particles are sintered with metal powders at high temperatures and pressures to form tool shapes. It produces exceptionally sturdy and wear-resistant tools, commonly used in sintered blades, ranging from 105 to 350 specifications.
2-6-1 (2)
The electroplating process can produce highly precise and durable diamond tools. The electroplating process ensures even distribution of diamond particles on the tool's edge. This technique is applicable to various types of diamond tools and materials, including blades, drill bits, grinding wheels, and more.
2-7-1 (2)
Vacuum brazed products is a versatile technique applicable to various types of diamond tools, including saw blades, drill bits, grinding wheels, and more. It operates effectively at high temperatures, making it suitable for processing hard materials like concrete, ceramics, and metals. Vacuum brazed edges are typically exceptionally robust, resulting in extended tool lifespans. Additionally, customized styles can be crafted to meet specific customer requirements
