Due to the high hardnes, PCD easy to produce high temperature in the process of machining, while high hardness leads to poor grinding efficiency,PCD is really difficult to grind materials.
How to choose abrasive for grinding PCD?
For machining PCD, we should choose material with high hardness,so diamond and CBN is ideal material for machining PCD.
Which kind of Bond grinding wheel is the ideal material for grinding PCD?
Most superabrasive grinding wheel are resin bond, while ceramic bond is more suitable for PCD material. Because the ceramic bond sintering can produce more pores, and the ceramic bond has advantages of good heat resistance and sharp cutting, so vitrified diamond grinding wheel is not easy to heat and expansion.
When grinding high hardness with vitrified diamond grinding wheel, grinding efficiency and precision will be higher than common resin diamond grinding wheel. Therefore, when machining PCD materials, the most suitable choice is to use vitrified bonded grinding wheels.
Suitale for PCD/PCBN cutting tools coarse/middle/finish and ultra-finish. In addition to grinding PCD/PCBN standard cutting tool, vitrified diamond grinding wheel also can grind PCD milling cutter, reamer and other custom tools 
Advantages of Moresuperhard vitrified diamond grinding wheel:
1. The porous structure of the abrasive layer makes the passivated diamond fall off faster, which can prevent vertical lines on the workpiece and improve the surface quality.
2. Perfect dimensional tolerance control, suitable for CNC and manual grinder.
3. Good self sharpening, high grinding efficiency, high wear resistance, low abrasive consumption.
4. PCD/CBN tool can achieve good surface finish after grinding with vitrified diamond grinding wheel, avoid cutting edge breakage, reducing the scrap rate, improve the precision of PCD/CBN tool.
5. The life of Vitrified diamond grinding wheel is 10 times than resin bond diamond grinding wheel,can achieve dressing online easily.

During the production process of ceramic diamond grinding wheels, raw materials such as diamonds and binders need to strictly control humidity and temperature. Excessive humidity may cause raw materials to absorb moisture, affecting the bonding strength and hardness of the grinding wheel; while excessive temperature may cause volatilization or unstable quality of certain materials, thus affecting the overall performance of the grinding wheel.
Single crystal diamond cutting tools are high-performance tools made from single crystal diamond, known for their exceptional hardness, wear resistance, and thermal conductivity.Effective grinding methods include using diamond grinding wheels, laser grinding, and mechanical grinding with cast iron or steel discs, each with its own advantages and requirements. Moresuperhard offers various solutions and consumables for grinding single crystal diamond tools, ensuring efficient production and high-quality results.
