New NEXTURN SA12B | Swiss Type Automatic Screw Machines

Description

Nexturn is the industry leader in swiss type CNC lathes. 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 SA12B is our entry level 12mm machine with a rotary synchronous guide bushing. It features a total of 7 axes (Z1, X1, Y, Z2, X2, C1, and C2) and 18 total tools. Machining capacity is 12mm on the main spindle, 12mm on the sub spindle, and 160mm (6.3”) maximum turning length in one chucking.

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 positiong of 1260”/min reduces cycle times. A lift up style operators door provides easy access to the machining area.

Spindles are the heart of the machine. The main spindle is a 3HP, 10,000 (12,000) RPM built-in motor spindle. The built-in motor provide outstanding acceleration / deceleration. The full Cs axis on both main and sub spindles with .001 degree positioning and pneumatic disc brake clamping (main spindle brake only) provide high rigidity for milling operation. The 1.4HP synchronous sub spindle allows simultaneous front and back working to be performed.

Powerful live tools provide excellent milling ability. With 1.3HP and 6,000 RPM on the cross unit and 0.7HP and 6000 RPM on the back side live tools , a wide range of milling, drilling, and tapping can be performed. ER-16 collets for the live tools provide excellent rigidty. 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.
