The model of the wheel is different, it is not the same, but if we buy it, if we do not watch, it is easy to buy the wrong, and it will be more time to change. So we should understand the model of the wheel, especially the users who often use it.
For example, if the wheel type is: SPA400 X 100 X 127, A60
The representative is the shape code. 400 represents the outer diameter D, 100 represents the thickness of H, 127 represents the aperture D, A represents the abrasive, 60 represents the granularity, L represents the hardness, 5 represents the organization number, B is the binder, and the 35 represents the highest working line speed m/s.
For the above summary, it is the method of the grinding wheel in view of the model. The different models may be different. We can refer to the above list to understand what each item represents, so that we can buy the products you need, and hope to help you.
