Main advantages of the CNC Lathe CKT 400x1000

CNC Lathe for metal CKT 400x1000 is a professional industrial solution combining modern technology with a rigid construction, ideal for facilities requiring high-precision cutting operations. As an advanced industrial lathe, it enables complex operations such as external, internal, and spherical turning, threading, drilling, and contouring — ensuring the highest surface quality. Key benefits include:

• High machining precision: Maximum turning diameter over bed 400 mm and over carriage 210 mm, with a minimum setting unit of 0.001 mm on X and Z axes, ensuring exceptional accuracy.
• Flexible spindle: Speed range 0–2000 rpm with spindle bore 86 mm and taper MT6 allows machining of a wide range of materials from steel to light alloys.
• Intuitive control: Siemens Sinumerik 808D system with Siemens servo drives offers a dedicated mode for conventional machine users, minimising the learning curve.
• Rigid construction: Net weight 1,950 kg and packing dimensions 2640x1500x1770 mm provide excellent stability when machining workpieces up to 1000 mm long.
• Tool efficiency: 4-position tool post (option 4 or 8 positions) for 20x20 mm tools (option 25x25 mm) speeds up tool change and reduces cycle time.
• Quick setup: Allows fast tool and zero point adjustment without program writing, ideal for single-piece production.
• Enhanced safety: Jogging and speed limits ensure accurate, safe operation and reduce the risk of errors.
• Component durability: Automatic lubrication of gears and guides reduces wear, extending the machine’s lifespan.
• Optimal cooling: The cooling system maintains thermal stability, protecting tools and workpieces during intensive machining.
• Versatile applications: Designed for precise turning in mechanical, automotive, and toolmaking industries — for both serial and small-batch production.
• Operating economy: The main motor of 5.5 kW combined with 6 Nm feed motors ensures high performance with low energy consumption.
• Integration with machining cycles: Cooperation with machining cycles such as turning, drilling, or threading requires only parameter input — no G-code knowledge needed.
• Customisation options: A wide range of options including Fanuc Oi-TF control, hydraulic chuck, bar feeder, or CAD/CAM software allows the machine to be tailored to specific production needs.

Construction and technology of the CNC Lathe CKT 400x1000

Industrial CNC Lathe CKT 400x1000 was designed for reliability and precision under demanding production conditions. Key construction elements include:

• Solid machine bed: Rigid construction with a net weight of 1,950 kg minimises vibrations, ensuring stability during machining.
• High-performance spindle: Bore 86 mm, taper MT6 and speed range 0–2000 rpm enable the machining of diverse workpieces.
• Tool post: 4-position (option 4 or 8) for 20x20 mm tools (option 25x25 mm) ensures fast tool changes and operational flexibility.
• Manual tailstock: With a sleeve taper MT4 and maximum stroke 120 mm, supports accurate workpiece alignment.
• Manual lathe chuck: Ensures secure clamping of components, with a hydraulic option available for higher productivity.
• Siemens servo drives: Guarantee smooth movement and high positioning precision (0.001 mm).
• Automatic lubrication system: Central lubrication of gears and guides reduces component wear.
• Cooling system: Maintains optimal temperature, improving machining quality and tool life.
• 24V halogen lighting: Provides excellent visibility in the working area, improving safety and precision.

Precision and performance

Numerical lathe CKT 400x1000 delivers outstanding precision thanks to the Siemens Sinumerik 808D control system and Siemens servo drives with a torque of 6 Nm on the X and Z axes. Advanced fixed cycles such as transverse turning, taper turning, threading, and contouring simplify programming and reduce machining time. Positioning accuracy of 0.001 mm on the X and Z axes, travel speed of X (8 m/min) and Z (10 m/min), combined with integration with machining cycles, ensures high-quality components with a diameter of up to 400 mm and length of 1000 mm.
