CNC Universal Center Lathe SUA 63, 80 90 NUMERIC

 The SUA NUMERIC multi-purpose center lathe is a numerically controlled machine designed for rough turning and finishing operations of shaft and flange parts, thread cutting, boring and turning tapers and various rotary surfaces. The machine comprises of a horizontal lathe bed with rigid design. The guide surfaces of the bed are hardened and ground. The counter surfaces on the saddle are lined with Turcite B sliding compound. The SUA Numeric features an automatic cycle control, which may be fitted with the control system Siemens 840D sl, Heidenhein 620, FAGOR or FANUC. A great advantage of the machine consists in automatic hydraulic shifting of three gears. The spindle speed can be continuously regulated within each of these three gears. The drive of the longitudinal feed - Z axis - is ensured via a servo drive connected directly to a ball screw. The drive of machines with a turning length exceeding 3,500 mm is performed using a special carriage box with backlash elimination. The feed is ensured via a rack. The drive of the cross feed - X axis - is ensured via a servo drive connected directly to the ball screw. The measuring of both feeds is performed by rotary transducers installed on the servomotors. For machines with long turning lengths, the Z axis feed is measured directly using linear scales. The machine can be fitted with both manually controlled tool heads and the multi-position CNC-controlled heads. In addition to this, the machine can also be equipped with a wide range of special accessories as well as custom accessories, including the chip conveyor.
