The Nexturn SA32XII Swiss-type lathe from Absolute Machine Tools features a 32-mm bar diameter capacity on the main and subspindle, and is available with or without a rotary synchronous guide bushing. The nine-axis machine (Z1, X1, Y1, Z2, X2, Y2, C1, C2 and optional B) can accommodate approximately 33 total tools with the B axis (29 without), and includes 19 live tools. The Swiss-type lathe can turn bar ranging to 210 mm (8") long in one chucking (60 mm or 2.36" without guide bushing).

The one-piece cast iron machine bed increases rigidity, and pre-tensioned ballscrews and LM guides increase accuracy, the company says.  High-speed positioning of 1,260 ipm reduces cycle times. A sliding operator door is designed to ease access to the machining area and is drip-free.

The main spindle features a 10-hp, 8,000-rpm built-in motor with effective acceleration/deceleration capabilities. The full C axis on both the main and subspindles features 0.001-degree positioning and pneumatic disc brake clamping to increase rigidity in milling operations. The synchronous subspindle enables simultaneous front and backworking to be performed.

Live tools (1.3 hp, 6,000 rpm) are designed to perform range of milling, drilling and tapping operations. ER-16 collets (ER-11 for back tools on the optional B axis) for the live tools provide rigidity. The optional B axis, used primarily for milling, drilling and tapping angles holes, provides 0 to 135 degrees of swiveling rotation with three front-side and three back-side live tools.
