Small metal parts can be made using various manufacturing processes, including Swiss machining and micromachining. CNC Swiss precision machining is a precision machining process that uses a sliding headstock lathe to produce small, complex metal parts. The process involves feeding long bar stock through a guide bushing to the cutting tool, allowing for precise and continuous machining. Swiss machining is ideal for producing small parts with intricate features and tight tolerances, such as those used in medical devices, aerospace components, and watchmaking. Micromachining, on the other hand, uses small cutting tools and high-speed spindles to produce very small metal parts. It is ideal for producing very small and precise parts, such as those used in microelectronics, medical devices, and aerospace components. The choice of process depends on the specific requirements and features of the part being produced.
