Swiss-type CNC uses guide bushings to support bar stock near the tool, enabling the machining of slender parts without deflection. Standard CNC turning employs chucks or collets to hold the workpiece, making it more suitable for shorter parts with larger diameters.

Swiss-type CNC easily achieves 20:1 length-to-diameter ratios, surpassing the 10:1 limit of standard turning. With proper tooling and support, some applications can even exceed 50:1.
Yes, modern Swiss-type CNC machines are equipped with multiple tool stations and live tooling capabilities. Off-center operations such as transverse drilling, milling, slotting, and hex broaching can all be completed in a single cycle.
Standard machined surface roughness is 125 Ra (3.2 µm); finish machining achieves 63 Ra (1.6 µm). Post-processing such as sandblasting or polishing can further improve surface quality.
We accept STEP(.stp), IGES(.igs), SolidWorks(.sldprt), Parasolid(.x_t), and STL files. For the most accurate quotes, STEP is the preferred format.
In CNC turning, the workpiece rotates while the tool remains stationary, suitable for cylindrical parts such as shafts, pins, and sleeves. In CNC machining, the workpiece is stationary while the tool rotates, ideal for flat, prismatic and complex 3D geometric shapes.
