Swiss Turned Parts

For long, slender parts with extreme precision requirements, we utilize Swiss-style sliding headstock lathes. This technology minimizes deflection by supporting the workpiece close to the cutting tool, allowing us to hold tolerances as tight as +/- 0.003mm. This process is ideal for the watchmaking, medical, and electronics industries where micromachining is required. Our Swiss machines are equipped with live tooling for milling, drilling, and cross-tapping, enabling the production of complete, complex parts in a single operation. We specialize in micro-machining materials ranging from tough titanium alloys to soft pure gold.
