Grinding Away

A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for a specific surface finish.

The machine consists of a table that traverses both longitudinally and across the face of the wheel. The longitudinal feed is usually powered by hydraulics, as may the cross feed, however, any mixture of hand, electrical, or hydraulic may be used depending on the ultimate usage of the machine (i.e., production, workshop, cost). The grinding wheel rotates in the spindle head and is also adjustable for height, by any of the methods described previously.

Depending on the workpiece material, the work is generally held by the use of a magnetic chuck. This may be either an electromagnetic chuck or a manually operated, permanent magnet-type chuck.

The machine has provisions for the application of coolant as well as the extraction of metal dust (metal and grinding particles).

Lubricants are sometimes used to cool the workpiece and wheel, lubricate the interface, and remove swarf (chips). It must be applied directly to the cutting area to ensure that the fluid is not carried away by the grinding wheel. Common lubricants include water-soluble chemical fluids, water-soluble oils, synthetic oils, and petroleum-based oils.
