The hardness of the grinding wheel needs to be measured. So we need to pay attention to the following details while doing these aspects. Failure to handle every detail can distort the results. So in the following measurements, we have to pay attention to every aspect.
The hardness of the grinding wheel is different, and the application range is also very different. So before using it, we need to determine its hardness. The hardness of some products such as resin grinding wheels varies greatly. During the measurement, the abrasive wheel contacts the surface of the material with a certain pressure. Determination of the resistance exhibited by a material during deformation. The same is true for Rockwell hardness testers. It is represented by the thickening of the plasticity of the indented material under the load (including preload and main load) of the indenter (diamond cone or quenched steel ball). Generally, the greater the indentation depth, the softer the material, and the smaller the indentation concentration, the harder the material. In addition, 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 one of the more commonly used methods.
In short, through the above summary, we can see that the most important thing in the measurement of grinding wheels and abrasive tools is the processing of various details. Every item in the measurement process is what we need to pay attention to, so we must understand each of the above items.
