In the preparation of metallographic samples, the preparation of thin slice samples is quite special, especially for metallographic consumables used in systems such as petrographic thin slice preparation, such as diamond cup grinding wheels, which not every metallographic consumable manufacturer can provide. But the new darling of QMAXIS metallographic consumables in the United States, the diamond cup grinding wheel, specializes in preparing thin plate samples. Here we go!

In the second half of 2020, the diamond cup grinding wheel, which is specially used to prepare thin slice samples, will be introduced into China, and tested and tried by the laboratories of University of Geosciences and Institute of Geosciences. The results are very satisfactory.


This diamond cup shaped grinding wheel from QMAXIS in the United States is suitable for precision cutting and grinding integrated machines, thin sample cutting and grinding systems, and petrographic precision cutting machines. Standard aperture, flanges, and other suitable components can be assembled with the above equipment for sample grinding and thinning.


The use of diamond cup shaped grinding wheels and diamond cutting blades can cooperate with each other in the cutting and grinding steps, thus completing unique thin sample preparation, simplifying the workflow and shortening the preparation time. At the same time, the prepared thin sheets can meet the technical requirements in terms of accuracy and surface flatness.

With the use and recognition of the QMAXIS diamond cup grinding wheel by the Petrography laboratory, the use of this diamond cup grinding wheel for preparing thin slice samples has been promoted, which has also brought confidence to more users of thin slice sample preparation.
