Eight-Axis Swiss-Type Lathe with Exchangeable Guide Bushing

The Nexturn SA-32PYII Swiss lathe is a 32 mm machine that comes standard with an exchangeable rotary synchronous guide bushing. This new model allows changeover from guide bushing to non-guide bushing depending on the application and material. Changing to non-guide bushing mode allows for the use of less expensive non-ground material and reduces remnant length, saving material costs.

The lathe features up to 8 total axes (Z1, X1, Y1, Z2, X2, Y2, C1, C2) and up to 25 total tools. Machining capacity is 32 mm on the main and sub-spindle, and 210 mm (8") maximum turning length with guide bushing and 60 mm (2.36") without the guide bushing. Nexturn Swiss machines use FANUC controls.

The machine is built for rigidity, accuracy, reliability and ease of use. The rigid one-piece cast iron machine bed is designed using FEM software. Powerful motors for both turning and milling deliver enhanced machining capability. The use of ultra-precision pre-tensioned ball screws and LM guides produce high accuracy. High speed positioning of 1,260 IPM reduces cycle times.

Spindles are the heart of the machine. The main spindle is a 10 HP, 8,000 RPM built-in motor spindle. The built-in motor provides enhanced acceleration / deceleration. The full C-axis on both main and sub spindles with .001° position and pneumatic disc brake clamping provide high rigidity for milling operation. The 5 HP integral motor synchronous sub spindle allows simultaneous front and back working to be performed. Powerful live tools, with 3 HP and 6,000 RPM on the crossmill unit and 1.3 HP and 5,000 RPM on the backend face tools, provide drilling and milling ability. A range of milling, drilling and tapping can be performed. ER-16 collets for the live tools provide enhanced rigidity. Rigid tapping is standard.

 The synchronous rotary guide bushing features a dual bearing structure with high accuracy. It has strong and accurate bearing support on both ends. The guide bushing is spline shaft driven. The machine can be changed in about 45 minutes to non-guide bushing for short parts, to reduce remnant length, and for use with non-ground bar stock.
