The primary structural component of a Sherline lathe, the bed, is typically constructed from aluminum. This material choice provides a foundation that is both rigid enough to support accurate machining operations and light enough for convenient portability. The specific aluminum alloy employed may vary, but it is generally selected for its strength, stability, and machinability.
The use of aluminum offers several advantages. Its inherent resistance to corrosion helps ensure the longevity of the machine. The relative ease with which it can be machined allows for precise shaping and the incorporation of features necessary for mounting other lathe components. Furthermore, the controlled expansion and contraction properties of aluminum contribute to maintaining accuracy during temperature fluctuations.
