SK50i CNC horizontal lathes

Introduction
Model SK50i is a CNC turning machine driven by servo spindle motor. It can be equipped with a 4-station turret (standard equipment) or 6-station turret for cutting different shapes of workpiece. With a nice and well-designed guard the machine is easy to operate and maintain; safety of operators is guaranteed. Standard equipment---Siemens 808D control has 7.5” color LCD and front-mounted USB interface, which ensures easy transfer of clients’ machining programs. Standard equipment--- separate coolant tank simplifies chip removal and machine cleaning.
The machine features smooth start and quick braking, and is designed for turning shaft-type and plate-type workpieces. Operations of internal and external cylindrical turning, arbitrary taper turning, arc turning, facing and metric/inch threading can be performed. The machine is suitable for small and middle batch production of multi-work, especially complex-shaped and high accuracy workpieces. 8” or10” hydraulic power chuck and hydraulic tailstock can be equipped on customers’ request.
