Condition: new, Year of construction: 2026, CKT 400 × 1000 CNC Lathe with Driven Tooling is an advanced CNC turning machine designed for precision machining of metal components in medium and large-scale production facilities. Equipped with the Siemens Sinumerik 808D CNC control system, it provides reliability, high accuracy, and ease of operation, meeting the requirements of modern industrial manufacturing processes. Key Features of the CKT 400 × 1000 CNC Lathe with Driven Tooling The CKT 400 × 1000 CNC metal lathe is a professional industrial solution offering: High machining precision – maximum swing over bed of 400 mm and swing over cross slide of 210 mm, with minimum setting resolution of 0.001 mm on both X and Z axes. Flexible spindle system – spindle speed range of 0–2000 RPM, spindle bore of 52 mm (optional 72 mm), and MT6 spindle taper provide versatility for various machining applications. Intuitive CNC control – Siemens Sinumerik 808D Advanced system with Polish-language interface and Siemens servo drives ensures easy operation and high process reliability. Rigid machine construction – net weight of 2000 kg provides excellent stability during machining of workpieces up to 1000 mm in length. Efficient tooling system – 4-position tool holder with driven tooling (optional 6 or 8 positions), supporting tools up to 20 × 20 mm (optional 25 × 25 mm), enables flexible machining operations. Fast setup and adjustment – convenient tool positioning, work zero setting, and corrections can be performed without writing complete CNC programs. Enhanced operator safety – controlled rapid movements and spindle speed limitation allow precise and safe machine operation. Extended component durability – automatic lubrication system for gears and guideways reduces wear and increases machine service life. Optimized cooling system – ensures thermal stability and protects cutting tools and workpieces during intensive machining. Energy-efficient operation – the 5.5 kW main motor combined with 6 Nm X and Z axis feed motors provides high productivity with optimized energy consumption. Integrated machining cycles – supports operations such as facing, taper turning, threading, and drilling by entering basic parameters without requiring advanced G-code programming knowledge. Customizable configuration – available options include Fanuc Oi-TF control, hydraulic chuck, bar feeder, and CAD/CAM software integration.
