Differences Between Thru-Feed And In-Feed Grinding

Thru-feed grinding is a type of centerless grinding. During this process, the workpiece passes through the machine itself. During this process, the workpiece passes through the machine itself. It proves to be an effective option for single-size diameter parts anywhere from a small dowel pin to a 16" shaft.

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.).
