CNC Swiss-Type Lathe Machining: The High-Precision, High-Efficiency Revolution in Precision Manufacturing
I. What is CNC Swiss-Type Lathe Machining?
The CNC Swiss-Type Automatic Lathe is a revolutionary high‑precision CNC turning machine. Unlike conventional CNC lathes, its key feature is the synchronized movement of the spindle and guide bushing, which provides continuous rigid support to the workpiece throughout machining. This completely eliminates vibration, tool‑push‑off, and deformation issues in slender shaft‑type parts caused by excessive overhang in traditional processing. In our equipment list, the Star RG series (13 machines) and Tsugami S205A (1 machine) form an industry‑leading Swiss‑type machining cluster, specializing in micro‑precision parts with diameters ≤ 21 mm.
