Dear Miya (MoreSuperHard staff): Thank you so much for providing the ceramic diamond grinding wheel, which is much better than the one we were using before from somewhere else. The  vitrified diamond dressing wheels  are very suitable for us and we like them very much! I would like to buy more grinding wheels for equip them on more machines.    We would like to say a BIG THANK YOU to you for delivering excellent feedback for our employees! Your loyalty and feedback have powered meaningful discussions within our organization, as well as countless improvements to our product and service. For that, we are so grateful.  Again, we appreciate the support and dedication from our customers.      Vitrified Diamond Dressing Wheel Customized PCD & CBN & CVD cutting, grinding, sharpening, brazing, regrind and retipped solution and service     MoreSuperHard is not only provides products for customers, but also solving problems for c...

High grinding force Diamond is the hardest substance among known minerals, and the amount of wear when matched with various metal and non-metal materials is only 1/50 ～ 1/800 of that of cemented carbide. The hardness (HV) of PCD is 80 ～ 120KN/mm², second only to single crystal diamond, and much higher than carbide. When PCD is grinding with diamond wheel, the initial cutting strength is very high, which is more than 10 times of the carbide (0.4MPa). The specific grinding can reach 1.2×104 ～ 1.4×105J/mm³; therefore, the grinding force is much higher than that of cemented carbide.       Small grinding ratio Due to the high hardness and wear resistance of PCD (relative wear resistance is 16 ~ 199 times of carbide), the grinding ratio of PCD is only 0.005 ~ 0.033, which is about 1/1000 ~ 1/100000 of carbide. The grinding efficiency is only 0.4 ～ 4.8mm3/min. Therefore, in order to ensure the quality and removal of cutting tools, the grinding time is very long and the processin...
