Through experimental research, we found that this method is more suitable for checking the grinding performance of ceramic diamond grinding wheels and ceramic CRN grinding wheels, because these two grinding wheels are much more wear-resistant than resin diamond grinding wheels, so the wheel consumption can be ignored. The specific operation method is as follows:
① First record the length value LI of the test block before grinding.
② Set the linear speed of the grinding wheel and the swing of the test block.
③ Set the running time of DHM-3.
After setting the above data through the touch screen, turn on the equipment to run. At the same time as running to the bad timing, DHM-3 automatically stops. Measure the length value of the test block after grinding 12. Calculate the grinding amount AL of the test block.
AL = LIº L2
When the grinding time is fixed, the larger the AL, the more wear-resistant and sharper the grinding wheel. The working process of DHM-3 basically simulates the on-site working process of the grinding wheel. Tests have proved that as long as the cemented carbide test block of consistent quality and appropriate size is selected as the standard test block, the grinding performance of the grinding wheel can be tested with DHM-3, so that the grinding wheel manufacturer can truly understand the grinding performance of the grinding wheel before its products leave the factory.
When individual users need to purchase a very expensive and special-sized grinding wheel, the diamond grinding wheel supplier can require the user to provide the parts to be ground as a standard sample, first make a sample of the grinding wheel for testing, and provide the grinding performance index to the user. When "meeting the requirements of use, lanthanum can be used as a large grinding wheel of suitable specifications, which can reduce the test cost.
Detection data processing is the touch screen operation interface of column measurement recording of DHM0. Through this interface, the working parameters required by Jiang can be easily recorded; through the status monitoring interface, the detection data can be observed and queried in real time.
Conclusion: The results of the user's on-site use prove that the "Experimental Testing Method for Grinding Performance of Diamond Grinding Wheels" proposed in this paper is a practical and relatively scientific testing method. We have provided a reliable testing equipment for the majority of diamond grinding wheel process formulation researchers and manufacturers, and solved the problem that the grinding wheel wear resistance and sharpness cannot be quantified, which has long puzzled grinding wheel formulation researchers.
