What Is Fine Grinding Of Metals In Metallurgy

Grinding (abrasive cutting) - Wikipedia

Grinding is a subset of cutting, as grinding is a true metal-cutting process Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc) [ citation needed ]
