The Nexturn SA32XII Swiss lathe is a 32 mm machine that is available with or without a rotary synchronous guide bushing. It features up to nine total axes (Z1, X1, Y1, Z2, X2, Y2, C1, C2 and optional B) and up to 33 total tools with the B-axis (29 without), including 19 live tools. Machining capacity is 32 mm on the main spindle, 32 mm on the sub-spindle, and 210 mm (8") maximum turning length in one chucking (60 mm or 2.36" without guide bushing).
"The machine is built for rigidity, accuracy, reliability and ease of use," said a company spokesperson. "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 1,260"/min reduces cycle times. A sliding operator door, as opposed to a lift up style door, provides easy access to the machining area and is drip free."
The main spindle is a 10 HP, 8,000 RPM built-in motor spindle. "The built-in motor provides outstanding acceleration / deceleration. The full C-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," said the spokesperson.
Live tools with 1.3 HP and 6,000 RPM can perform a wide range of milling, drilling and tapping. ER-16 collets (ER-11 for back tools on the optional B-axis) for the live tools provide rigidity. Rigid tapping is standard. The optional B-axis, used primarily for milling, drilling and tapping angled holes, provides 0 - 135 degrees of swiveling rotation with three front side and three back side live tools. The front side tools can be used for both front and face work, doubling the useful tools to six possible.
The synchronous rotary guide bushing features a dual bearing structure designed for high accuracy. It has strong and accurate bearing support on both ends. The guide bushing is spline shaft driven. The guide bushing is necessary for precision machining of long parts. The machine can be ordered without the guide for short parts, reduced remnant length and the ability to run cold drawn material.
"Nexturn uses the highest quality components to produce the best product possible such as: FANUC controls, motors, and drives (Japan); NSK ballscrews and THK linear motion guideways (Japan); NSK and FAG bearings (Japan and Germany); KHK gears (Japan); Mayr couplings (Germany); CKD pneumatic valves (Japan); SMC pneumatic cylinders (Japan); and Daikin hydraulic systems (Japan)," said the spokesperson.
