Standard turning supports a maximum slenderness ratio of 10:1. For longer, finer parts (exceeding 10:1), CNC lathes with center support are recommended to ensure high accuracy.

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.
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.
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.
We accept STEP(.stp), IGES(.igs), SolidWorks(.sldprt), Parasolid(.x_t), and STL files. For the most accurate quotes, STEP is the preferred format.
Choose turning-milling for complex parts with tight positional tolerances. It eliminates re-fixturing errors, reduces lead time, and lowers total cost.
