2025 05 13 The main difference between CNC Swiss machining and traditional CNC machining lies in how the material is supported and moved: Swiss machines move the bar stock through a sliding headstock, improving stability for small, high-precision parts, while traditional CNC machines keep the workpiece stationary. Swiss machining is ideal for complex, long, small-diameter components requiring tight tolerances.
