Grinding wheels and abrasive tool factories remind everyone that the hardness of grinding wheel and abrasive tools needs to be measured. Therefore, you need to pay attention to the following details when working on these aspects. Every detail mishandled can distort the result. Therefore, in the follow-up measurement, we should pay attention to all aspects of measuring the hardness of the grinding wheel and the grinding tool.
The hardness of the grinding disc is different, and the scope of application is also very different. Therefore, we should determine the hardness of the grinding wheel before use. The hardness of some resin grinding wheel discs and other products varies greatly. During the measurement, the grinding wheels and the abrasive tools contact the surface of the material with a certain pressure to measure the resistance of the material during deformation.
The same is true for Rockwell hardness testers. It is represented by the plastic thickening of the compressed material under the action of an indenter (diamond cone or hardened steel ball) under load (including preload and main load). Generally, the deeper the pressed material, the softer the material, and the lower the pressed concentration, the harder the material.
In addition, according to the experience of the grinding wheel factory, the methods for measuring the hardness of abrasive tools include hand cone method, mechanical cone method, Rockwell hardness tester method and sandblasting hardness tester method. The Rockwell hardness test method is the most commonly used one.
In short, we can see from the summary of the grinding wheel factory above. When measuring grinding wheels and abrasive tools, it is very important to take care of every detail. Every item in the measurement process is what we need to pay attention to, so we need to understand each of the above.
