Base Materials of Sintered Diamond and CBN Wheels
The base materials for sintered diamond wheels primarily include:
Aluminum Base: For aluminum-based metal bond wheels, the abrasive layer must be separately sintered and then bonded onto the aluminum base followed by precision machining. It’s important to note that aluminum bases cannot be placed in the sintering furnace with the abrasive layer, as the aluminum base could deform or even melt at high temperatures.
Steel Base: Steel-based metal bond wheels can be placed in the sintering furnace together with the abrasive mixture. This method ensures a more robust and integrated bond between the abrasive and the base, resulting in a cohesive structure.
Features
Key Components of Metal Bonding Agents
Metal bond agents are critically composed of multiple alloys. Key components include:
Copper/Tin Bronze (Cu/Sn)
Cobalt Bronze (Co/Cu)
Tungsten Carbide (W/WC)
Iron-Copper-Tin System Alloys (Fe/Cu/Sn)
Common copper/tin alloy ratios are generally 85:15 or 80:20, with additional fillers and alloying elements added to enhance performance. Particularly in diamond tools for stone drilling and cutting, metal bonding agent selection is paramount. Tools based on tungsten, tungsten carbide, or cobalt alloys offer high wear resistance and toughness, forming a favorable small-sized tungsten carbide interface layer with diamond particles, enhancing mechanical holding and chemical bonding strength.
Characteristics of Metal Bond Diamond and CBN Grinding Tools
Wear Resistance: High wear resistance suitable for prolonged, high-load grinding operations.
Strength: High strength abrasive bonding, ideal for heavy-duty grinding and rough grinding.

Advantages Over Other Bonding Types of Diamond and CBN Wheels
Durability: metal bond exhibit high strength and toughness, resisting impact and wear during grinding, extending wheel service life.
Thermal Conductivity: As a metal bonding agent, bronze effectively conducts heat away, preventing workpiece thermal deformation and burns.
Grinding Precision: Bronze sintered diamond/CBN wheels maintain high precision and stability during grinding, meeting high-precision requirements.
Dressing Bronze Sintered Diamond and CBN Wheels
Sintered diamond wheel dressing can be achieved through various methods:
Online Electrolytic Dressing:
Applied to precision metal bond diamond wheels, where the grinding wheel acts as the anode, and a cathode is mounted on the wheel end face. A soluble chemical grinding fluid is supplied to the gap between the wheel and the workpiece. When current passes between the electrodes, electrolytic action erodes excess metal, exposing the diamond abrasives for grinding.
EDM Dressing:
Utilizes heat energy or electrical sparks between the electrode and rotating metal bond diamond wheel to remove excess metal material from the wheel surface. This method achieves well-defined abrasive exposure heights, enhancing grinding performance.

Application
Applications of Sintered(metal bond) Diamond/CBN Wheels
Metal Bond Diamond Tools:
Primarily used for grinding high-hardness brittle non-metallic materials such as optical glass, ceramics, gemstones, and stone. These tools are widely used for infeed grinding, forming grinding on optical curve grinders, regrinding single-edged tools, grinding spiral grooves on small drills, and are suitable for electrolytic grinding.
Metal Bond CBN Tools:
CBN abrasives demonstrate unique advantages when grinding specific materials, making them indispensable in aerospace, automotive manufacturing, mold processing, and other industries. Compared to diamonds, CBN abrasives have higher thermal stability and chemical stability, especially suitable for grinding ferrous metals and high-hardness, tough metal materials. Metal bond CBN tools exhibit high hardness and strength, capable of enduring significant grinding pressures and impacts, making them ideal for high-efficiency batch grinding processes.
