Both processes turn parts. The difference is how the workpiece is supported while it is cut — and that decides whether your part is easy, difficult or effectively impossible.
In conventional CNC turning the workpiece is gripped and rotated by the spindle, and the tool cuts on the outside. In Swiss-type (sliding-headstock) machining the bar stock is fed forward through a guide bushing and the tool cuts right at the bushing, so the material is supported almost at the point of cut.
A slender turned part deflects under cutting force, producing taper, chatter and run-out. The guide bushing removes that problem by supporting the material millimetres from the tool, which is why Swiss-type machines are the natural choice for high length-to-diameter ratios.
Our Swiss-type turning covers Ø 2–65 mm and lengths up to 300 mm. Conventional turning then takes over for larger diameters and shorter, stiffer parts where the guide bushing adds nothing.
Modern Swiss-type machines carry live tooling, so cross-holes, flats, slots and even light milling can be done in the same cycle. For small, complex, high-volume parts that means one set-up and a short cycle; for a short-run, chunky part, conventional turning is usually the more economical route.
