The tool applies abrasion and knocks off all used or clogged abrasives until the grinding wheel has a nice new abrasive surface. Operators frequently need to repeat the process, sometimes as often as every 10 minutes depending on the materials ground, which can be labour intensive and decrease productivity.

Surface Finish is a measure of the overall texture of a surface that is characterized by the lay, surface roughness, and waviness of the surface. Surface Finish when it is intended to include all three characteristics is often called Surface Texture to avoid confusion, since machinists often refer to Surface Roughness as Surface Finish.

Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications, it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth.

The main reason for grinding is to let the water come in contact with a larger surface area of the coffee beans. The grind can be divided into coarser and finer grinds. These affect how much water can come in contact with the surface area of the beans as well as affect the brewing time and how good you will be able to extract the flavors.
