Moresuperhard diamond wheel for precision grinding single crystal diamond, With Ultra-high precision. The PG seris is a CNC grinding machine for single or mono crystal diamond tool manufacture. The PG seris enables the automated production of ultra-high precision diamond tools.
Coborn PG series offers automated, ultra-high precision grinding, designed to meet the most complex of demands by toolmakers working with natural (MCD) or synthetic single crystal diamond (SCD), manufactured by either high pressure high temperature (HPHT) or chemical vapour deposition (CVD).
The applications of diamond grinding wheels
Diamond grinding wheels are used for grinding PCD cutting tools, PCBN cutting tools, CVD tools, MCD tools, milling cutter, reamer, drill and regrinding etc. It can be used for making facetted and convex radius tools using: natural diamond, HPHT, synthetic diamond, CVD synthetic diamond.
MCD tools are used for milling carbon steel, die steel, alloy steel, stainless steel, heat-resistant steel, gray cast iron, ductile iron, malleable iron, etc.

Vitrified Bond Diamond Grinding Wheel
Precision grinding for natural diamond (MCD) or synthetic single crystal diamond (SCD) cutting tools.
Metal Bond Diamond Grinding wheel
Natural (MCD) or synthetic single crystal diamond (SCD), manufactured by either high pressure high temperature (HPHT) or chemical vapour deposition (CVD). Metal bond diamond wheel can used for single crystal diamond tool manufacture with ultra-high precision.
Single crystal diamond grinding method
This is the case of our customer want to grind MCD cutting tools, he purchase Moresuperhard W20 and W10 grit vitrified diamond grinding wheel. First steep using 800#, second steep using 1500#,finally using 10000# for finishing. The customer wants the final chipping control to be 0.002 ,and have a feedback that Moresuperhard W20 vitrified diamond grinding wheel is the best W20 he has used. Moresuperhard W10 vitrified diamond grinding wheel chipping can reach 0.01-0.013(200 times), can meet the requirements of semi-fine grinding, grinding force is also very good.
Moresuperhard also have second grinding method:
You can using W40, W10 and W5,and finally using #10000 vitrified diamond grinding wheel for finish grinding. In order to improve the opening efficiency, the customer directly grinds the Australian ceramic base W40, which has a higher efficiency.Then using W10 vitrified diamond grinding wheel for semi-finish grinding ,chipping is 0.019mm ,chipping is a little too big.
And using W5 vitrified diamond grinding wheel, while the operator think the grindng efficiency is low, but we suggest customer that you need dressing the grinding wheel and then using it. After dressing,vitrified diamond grinding wheel grinding amount can reach 0.02 mm(using 5 minute).
Comparasion between two grinding method:
According to second grinding method, we suggest our customer first using W40, second using W20 and then using W10. First grinding method do not using W40, it just effect the grinding efficiency but can ensure the chipping. Using W40 for rough grinding, the chipping is not ideal,so we sugest using W20 to improve the grinding efficiency and control the chipping. And then finish grinding the MCD cutting tools , it do not occur big chiiping and the chipping can control.
After grinding with W10, the chipping is 0.019, which is related to rough grinding with W40. During fine grinding, it is necessary to grind the chipping and ensure the edge width 0.03mm, which requires many factors, including machine feed accuracy, technology, software and grinding wheel, etc.
PCD and CBN cutting tools are widely used in metal cutting and processing nowadays.“More Super Hard Products” devotes to offer an efficiency and economic solution in PCD and CBN cutting tools grinding.
