New NEXTURN SA-32PY-II (STOCK) | CNC Lathes

Description

Nexturn is the industry leader in Swiss type CNC lathes. Nexturn has many industry firsts, including the first to produce a 38mm CNC Swiss machine. The use of top quality components combined with cutting edge technology produces a state-of-the-art machine with industry leading performance. Nexturn machines use only the best components:

• Fanuc CNC controls and motors (Japan)
• NSK ballscrews and THK linear guideways (Japan)
• NSK bearings (Japan) and FAG bearings (Germany)
• KHK gears (Japan)
• Mayr couplings (Germany)
• CKD pneumatic valves (Japan)
• SMC pneumatic cylinders (Japan)
• Daikin hydraulic pump and valves (Japan)

The SA-32PYII is our high-level 32mm machine with an exchangeable rotary synchronous guide bushing. The exchangeable, or removable, guide bushing allows the changeover from using ground barstock to less expensive non-ground stock with a reduced remnant length. It features a total of 8 axes (Z1, X1, Y1, Z2, X2, Y2, C1, and C2) and 25 total tools. Machining capacity is 32mm on the main spindle, 32mm on the sub spindle, and 210mm (8”) maximum turning length in one chucking (60mm or 2.36” when guide bushing is removed).

The machine is built for rigidity, accuracy, reliability, and ease of use. The highly rigid one piece cast iron machine bed is designed using FEM software. Powerful motors for both turning and milling deliver outstanding machining capability. The use of ultra-precision pre-tensioned ballscrews and LM guides produce high accuracy. High speed positioning of 1260”/min reduces cycle times. A sliding operator’s door, as opposed to a lift up style door, provides easy access to the machining area and is drip free.

Spindles are the heart of the machine. The main spindle is a 10HP, 8000 RPM built-in motor spindle. The sub spindle is a 5HP built-in motor spindle. The built-in motors provide outstanding acceleration / deceleration. The full Cs axis on both main and sub spindles with .001 degree position and pneumatic disc brake clamping provide high rigidity for milling operation. The synchronous sub spindle allows simultaneous front and back working to be performed.

Powerful live tools sporting 3HP and 6,000 RPM on the cross mill unit and 1.3HP and 5,000 RPM on the backend face tools, provide excellent drilling and milling ability. A wide range of milling, drilling, and tapping can be performed. ER-16 collets for the live tools provide excellent 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. The optional non-guide bushing kit is required for use without the guide bushing.
