While both involve reducing the size of materials, they are actually two distinct processes. Crushing involves applying a force to materials to break them apart, often using compression or impact. Grinding, on the other hand, involves reducing the size of materials using friction, shear, or impact between two surfaces.

In contrast, grinding is the more suitable machining operation if you have a partially-machined work surface that needs minor tweaks or finishing touches. Grinding can also be used for machining large billets of material, but it's more useful for metal. Milling is more versatile because you can also turn plastics.
