Machining 101: What is Grinding? | Modern Machine Shop

Evan Doran. Assistant Editor. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

What is Abrasive Machining?

Abrasive machining grinding machines will incorporate hydrostatics, air, and combination squeeze-film technology. Such spindles will be transmitting far higher power (40 to over 100 hp, or 30–75 kW) than that employed in a conventional surface grinding system of similar table size. This is a major difference in precision grinding compared ...
