Main advantages of the CNC Lathe CORMAK CKT400x700

The CORMAK CKT400x700 CNC lathe for metal is a professional industrial solution that combines modern technology with a rigid structure, ideal for facilities requiring precise cutting operations. As an advanced industrial lathe, it enables complex operations such as external and internal turning, threading, grooving, drilling, and contouring while maintaining the highest quality of finished parts. Its key benefits include:

• High machining precision: Maximum turning diameter over the bed 400 mm and over the carriage 160 mm, with a spindle bore of 48 mm, ensuring positioning accuracy of 0.01 mm and repeatability of 0.012 mm.
• Flexible spindle: Speed range 150–1,800 rpm with A2-6 spindle nose enables machining of a wide variety of materials, from steel to light alloys.
• Advanced control: The Siemens Sinumerik 808D system, supported by Siemens servo drives, offers intuitive fixed cycles for facing, taper turning and threading, reducing programming time.
• Rigid construction: Net weight 1,800 kg and dimensions 2,200x1,100x1,620 mm ensure stability when machining parts up to 700 mm long.
• Tool efficiency: The 8-position turret with 20x20 mm tools (option for 6 or 8 positions) speeds up tool changes and minimises production cycle time.
• Accurate clamping: 3-jaw manual chuck (optional hydraulic) and manual tailstock (optional hydraulic) with MK5 taper ensure secure workpiece holding.
• Component durability: The automatic lubrication system for 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.
• Versatility of application: Designed for precision turning in mechanical, automotive, and tool industries for both series and small-batch production.
• Operational economy: A 5.5 kW motor combines high performance with low energy consumption.
• Customisation capability: Wide range of options such as Fanuc Oi-TF control, tool probe, bar feeder, or CAD/CAM software allow full adaptation to specific requirements.

Construction and Technology of the CNC Lathe CORMAK CKT400x700

The industrial CNC lathe CORMAK CKT400x700 was designed for reliability and precision under demanding production conditions. Key structural components include:
