We use abrasive products such as grinding wheels because of their speed, ability to repeat form, and achieve finish. When trying to select the correct wheel specification, we need to look at the operation and establish whether we are looking for rapid stock removal or a finer finish. Whether the part is simple/flat or if there is a form to hold.
