Key advantages of the CKT 400x1000 CNC lathe 

with a powered tool

The CKT 400x1000 CNC metal lathe is a professional industrial solution that combines advanced technology with a robust design, tailored for facilities requiring precision machining. As an industrial lathe, it enables the execution of complex operations, such as turning external, internal and spherical surfaces, threading, drilling, grooving and contouring, ensuring the highest quality of workpieces. Its key benefits include:

• High machining precision: A maximum turning diameter of 400 mm over the bed and 210 mm over the cross slide, with a minimum positioning increment of 0.001 mm on the X and Z axes, guarantees exceptional component accuracy.
• Flexible spindle: A speed range of 0–2,000 rpm, a spindle bore of 52 mm (72 mm optional) and an MK6 taper enable the machining of a wide range of materials, from steel to light alloys.
• Intuitive control: The Siemens Sinumerik 808D system in Polish, featuring Siemens servo drives, offers a dedicated mode for users of conventional machines, minimising the learning curve for working with CNC.
• Rigid construction: A net weight of 2,000 kg and packaging dimensions of 2,640 × 1,500 × 1,770 mm ensure stability when machining workpieces up to 1,000 mm in length.
• Tooling efficiency: A 4-position tool holder (6 or 8-position option) with 20 × 20 mm tools (25x25 mm option) and a head with a driven tool – speeds up tool changes, reducing production cycle times.
• Quick set-up: Enables convenient setting of tools and zero points, as well as making adjustments without the need to write a programme – ideal for single-piece production.
• Enhanced safety: Control movements and speed limits allow for precise and safe manoeuvring of the machine, minimising the risk of errors.
• Component durability: An automatic lubrication system for gears and guides reduces wear, extending the machine’s service life.
• Optimal cooling: The cooling system ensures thermal stability, protecting tools and workpieces during intensive machining.
• Versatility of application: Designed for precision turning in the mechanical engineering, automotive and toolmaking industries, for both mass production and small-batch production.
• Cost-effective operation: The 5.5 kW main motor, combined with 6 Nm feed motors, combines high performance with low energy consumption.
• Integration with machining cycles: Working with machining cycles such as cross-turning, conical turning, threading or drilling requires only the entry of basic parameters, without the need for knowledge of G-codes.
• Customisation options: A wide range of options, such as Fanuc Oi-TF control, a hydraulic chuck, a bar feeder or CAD/CAM software, allows the machine to be tailored to specific requirements.
• European safety standards: The CE Declaration of Conformity confirms compliance with stringent occupational safety standards.
