with driven tool

CKT 400x1000 CNC metal lathe is a professional industrial solution combining advanced technology with a rigid mechanical structure, dedicated to facilities requiring precise cutting operations. As an industrial CNC lathe, it enables complex machining processes such as external, internal and spherical turning, threading, drilling, plunge cutting and contouring, ensuring excellent workpiece quality. Its key benefits include:

• High machining accuracy: Maximum turning diameter over bed 400 mm and over cross-slide 210 mm, with a minimum setting increment of 0.001 mm on X and Z axes, ensures exceptional precision.
• Flexible spindle: Speed range 0–2000 rpm, spindle bore 52 mm (option* 72 mm) and MK6 taper allow machining of a wide range of materials, from steel to light alloys.
• Intuitive control: Siemens Sinumerik 808D control with Siemens servo drives offers a dedicated mode for operators familiar with conventional machines, reducing the learning curve when transitioning to CNC.
• Rigid construction: Net weight 2000 kg and packing dimensions 2640x1500x1770 mm provide stability during machining of workpieces up to 1000 mm in length.
• Tooling efficiency: 4-position tool post (option* 6 or 8 positions) for 20x20 mm tools (option* 25x25 mm) combined with a driven tool head speeds up tool changes and shortens production cycles.
• Quick setup: Allows convenient tool setting, zero point definition and corrections without the need to write a program, ideal for one-off and prototype production.
• Enhanced safety: Jog movements and speed limitation enable precise and safe machine handling, reducing the risk of operational errors.
• Component durability: Automatic lubrication system for gears and guideways reduces wear and extends machine service life.
• Optimal cooling: Integrated coolant system ensures thermal stability, protecting tools and workpieces during intensive machining.
• Application versatility: Designed for precision turning in mechanical engineering, automotive and tooling industries, suitable for both batch and small-series production.
• Operating efficiency: Main motor power 5.5 kW with 6 Nm feed motors combines high performance with reduced energy consumption.
• Integration with machining cycles: Built-in cycles such as facing, taper turning, threading and drilling require only basic parameter input, without the need for G-code knowledge.
• Customisation options: A wide range of options such as Fanuc Oi-TF control, hydraulic chuck, bar feeder or CAD/CAM software allows the machine to be tailored to specific production needs.
• European safety standards: CE certification confirms compliance with stringent workplace safety regulations.

Design and technology of the CNC lathe CKT 400x1000

with driven tool

Industrial CNC Lathe CKT 400x1000 has been designed for reliability and precision under demanding production conditions. The key structural components include:

• Rigid machine bed: Heavy-duty cast structure with a net weight of 2000 kg minimises vibrations, ensuring stable operation during machining.
• High-performance spindle: Bore 52 mm (option* 72 mm), MK6 taper and 0–2000 rpm speed range enable efficient processing of various materials.
• Tool post: 4-position (option* 6 or 8) with 20x20 mm tools (option* 25x25 mm) ensures quick tool change and flexible operations.
• Hydraulic tailstock: Equipped with MK5 taper sleeve and 120 mm travel for accurate support of workpieces.
• Manual chuck: Ensures secure clamping of workpieces, with a hydraulic chuck available (option*) for increased efficiency.
• Siemens servo drives: Guarantee smooth movement and high positioning accuracy (0.001 mm).
• Automatic lubrication system: Central lubrication for gears and guideways minimises wear and maintenance effort.
• Cooling system: Maintains optimal temperature, improving tool life and machining quality.
• 24V halogen lighting: Provides excellent workspace visibility, improving safety and precision.

Precision and performance

CNC Lathe CKT 400x1000 delivers exceptional precision thanks to Siemens Sinumerik 808D control and Siemens servo drives providing 6 Nm torque on X and Z axes. Advanced built-in machining cycles – facing, taper turning, threading, plunge cutting and contouring – simplify programming and reduce machining time. Positioning accuracy of 0.001 mm on both axes, feed rates of X (8 m/min) and Z (10 m/min), and integration with technological cycles guarantee consistent quality of workpieces up to 400 mm in diameter and 1000 mm in length.
