Advantages of Single Crystal Diamond Tools
With the advent of modern integrated technology, machining is developing in the direction of high precision, which places very high requirements on tool performance. Due to the small friction coefficient, low thermal expansion coefficient and high thermal conductivity of single crystal diamond, it can cut extremely thin chips. The chips flow out easily. It has low affinity with other substances and is not easy to produce built-up edge. It generates little heat and has high thermal conductivity. It can Avoid the impact of heat on the blade and workpiece, so the blade is not easily dulled, the cutting deformation is small, and a higher quality surface can be obtained.
Customer CVD diamond tools grinding case
Workpieces :Inner concave MCD/CVD cutting tools
Grinding Requirement:Chipping control under 5μm
Grinding machine:Anca cnc grinding machine
Customer try to use resin bond diamond grinding wheel for grinding CVD single crystal diamond tools,But there are two problems that need to be solved.
1.Chipping control:The chipping is not up to standard and cannot be controlled within 5μm.
2.Low grinding efficiency:The grinding wheel is consumed too quickly, but the amount of workpiece removal is not obvious.
Moresuperhard has rich experience in grinding CVD/MCD diamond cutting tools.Usually,vitrified bond diamond grinding wheels are more suitable for grinding single crystal diamond cutting tools and moresuperhard' fine grain sizes ceramic diamond grinding wheel has good performance in grinding diamond tools.
According to the customer's grinder, Moresuperhard customizes a 1A1 parallel ceramic diamond grinding wheel for testing.Let’s look forward to a successful test result.
Comparison of the grinding effects of single crystal diamond tools with different particle size ceramic diamond grinding wheels in Moresuperhard
| Grain Sizes | Chipping |
| W20 | 30μm-35μm |
| W10 | 15μm-20μm |
| W5 | 5μm-7μm |
| W1.5 | 3μm-5μm |
This is a grinding experiment data,the specific grinding results need to be determined according to the grinding machine and grinding parameter settings.

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.
