microlathes

A microlathe is a miniature precision lathe designed for machining very small parts. These machines are typically used in hobbies, jewelry making, watchmaking, and in scientific research for creating micro-components. Microlathes are characterized by their small size, often fitting on a workbench, and their ability to achieve very fine tolerances and smooth finishes.

The fundamental operation of a microlathe is similar to that of a full-sized lathe. It consists of a bed, a headstock that holds and rotates the workpiece, and a tailstock that supports the other end of the workpiece or holds tooling. A tool post is used to hold cutting tools, which are advanced by hand or by a small lead screw to remove material from the rotating workpiece. Common operations include turning, facing, knurling, and threading on a micro scale.

Materials that can be machined on a microlathe include soft metals like brass and aluminum, as well as plastics and certain woods. The precision achievable with these machines allows for the creation of intricate parts such as tiny screws, gears, pins, and decorative elements. Power sources for microlathes can range from small electric motors to manual hand cranks, depending on the model and intended use. Their compact nature and relatively low cost make them accessible tools for individuals and small-scale professional applications requiring high precision on miniature scales.
