Polishing workpieces of stainless steel is costly and exhausting depending on the demanded surface quality. The reasons for a polished surface can be of various kinds.

Besides its visual appeal, polishing is often required for reasons of hygiene, for instance in canteen kitchens and appliances for manufacturing medicines. Surfaces of this kind require particular attention before work even starts if the result is to not only be a mirror finish but also fall within the roughness tolerances.

The first step must not begin with overly coarse abrasives. The first grinding operation should therefore not use a grain size exceeding 60. If the workpiece shape allows this, grinding in a crosswise fashion facilitates subsequent polishing. In the following steps, it is important that successively finer grain sizes be used if they are to remove completely the grinding marks left by the previous grain. Depending on the abrasive used, normal grain or 311 Trizact abrasives, this process must continue down to a grain size of 600.

If a glossy surface is needed for decorative purposes, the difference between grain sizes between grinding operations can be a little larger. After rough grinding, the required surface is generated in a three stage polishing process consisting of prepolishing, polishing and finishing.

Flexible shaft machines are ideal for these applications because the powerful, heavy drive unit is isolated from the actual tool, therefore making the work easier and far less fatiguing.
