Main advantages of the CKT 400x1000 CNC lathe

with driven tool

CKT 400x1000 CNC metal lathe is a professional solution for industry, combining advanced technology with solid construction, dedicated to plants requiring precision machining. As an industrial lathe, it enables complex operations such as turning external, internal and spherical surfaces, threading, drilling, plunge cutting and contouring, ensuring the highest workpiece quality. Its key benefits include:

• High machining precision: Maximum turning diameter over the bed of 400 mm and over the carriage of 210 mm, with a minimum setting unit of 0.001 mm on the X and Z axes, guarantees exceptional workpiece accuracy.
• Flexible spindle: Speed range of 0-2000 rpm, spindle bore of 52 mm with the option of 72 mm and MT6 taper enable machining of a wide range of materials, from steel to light alloys.
• Intuitive control: The Siemens Sinumerik 808D system with Siemens servo drives offers a dedicated mode for users of conventional machines, minimising the entry barrier to CNC work.
• Rigid construction: Net weight of 2000 kg and packaging dimensions of 2640x1500x1770 mm ensure stability when machining workpieces up to 1000 mm long.
• Tooling efficiency: 4-position tool post with the option of 6 or 8 positions, 20x20 mm tools with the option of 25x25 mm, and a driven tool head speed up tool changes, shortening the production cycle time.
• Quick setting: Enables convenient setting of tools and zero points, as well as corrections without the need to write a programme, ideal for one-off production.
• Increased safety: Jog movements and speed limitation allow precise and safe machine manoeuvring, minimising the risk of errors.
• Component durability: The automatic lubrication system for the gearbox and guideways reduces wear, extending the machine’s service life.
• Optimal cooling: The cooling system ensures thermal stability, protecting tools and workpieces during intensive machining.
• Versatile applications: Designed for precision turning in the mechanical, automotive and toolmaking industries, both in series and small-batch production.
• Operating economy: The main motor with 5.5 kW power and 6 Nm feed motors combines high performance with low energy consumption.
• Integration with technological cycles: Cooperation with machining cycles such as facing, taper turning, threading or drilling requires only basic parameters to be entered, without knowledge of G-codes.
• Personalisation option: A wide range of options, such as Fanuc Oi-TF control, hydraulic chuck, bar feeder or CAD/CAM software, allows the machine to be adapted to specific requirements.
• European safety standards: The CE declaration of conformity confirms compliance with strict occupational safety standards.

Construction and technology of the CKT 400x1000 CNC lathe

with driven tool

CKT 400x1000 industrial CNC lathe has been designed for reliability and precision in demanding production conditions. Key construction elements include:

• Solid machine bed: Rigid construction with a net weight of 2000 kg minimises vibration, ensuring stability during machining.
• High-performance spindle: Bore of 52 mm with the option of 72 mm, MT6 taper and speed of 0-2000 rpm enable machining of various workpieces
• Tool post: 6-position with the option of 8, with 25x25 mm tools, ensures quick tool changes and operational flexibility.
• Hydraulic tailstock: With sleeve taper MT5 and maximum travel of 120 mm, supports precise workpiece support.
• Manual lathe chuck: Ensures secure workpiece clamping, with a hydraulic option for increased efficiency.
• Siemens servo drives: Guarantee smooth movement and high positioning accuracy (0.001 mm).
• Automatic lubrication system: Central lubrication of the gearbox and guideways reduces component wear.
• Cooling system: Maintains the optimum temperature, improving machining quality and tool life.
• 24V halogen lighting: Provides excellent visibility of the working area, increasing safety and precision.

Precision and work efficiency

CKT 400x1000 numerically controlled lathe offers exceptional precision thanks to Siemens Sinumerik 808D control and Siemens servo drives with a torque of 6 Nm on the X and Z axes. Advanced fixed cycles, such as facing, taper turning, threading, plunge cutting and contouring, simplify programming and shorten machining time. Positioning accuracy of 0.001 mm on the X and Z axes, X-axis movement speed (8 m/min) and Z-axis movement speed (10 m/min), as well as integration with technological cycles, ensure high-quality workpieces up to 400 mm in diameter and 1000 mm in length.

Application of the CKT 400x1000 CNC metal lathe

CNC metal lathes such as the CKT 400x1000 are used in various industrial sectors, including:
