• Process optimisation: The 3-jaw hydraulic chuck and complete set of soft jaws increase clamping flexibility and reduce setup time.

Construction and Technology of the Industrial Lathe

The CORMAK CK7135A CNC metal lathe has been designed with reliability and precision in mind for demanding industrial environments. The use of high-quality components such as Siemens drives and HIWIN linear guides guarantees stable performance and a long machine lifespan.

Slant Bed Construction

The 45° slant bed and HIWIN linear guides ensure outstanding rigidity, minimising vibrations during machining. Telescopic covers protect the guides from contamination, increasing durability and reliability.

Spindle and Drive

The spindle, with a through-hole of 56 mm and a 5.5 kW motor, allows for efficient machining of various shapes and materials within a spindle speed range of 200–3500 rpm, ensuring excellent surface finish quality.

Tool Turret

The turret-type tool holder with 6, 8, or 12 tool positions (depending on configuration) eliminates unnecessary movements, shortens machining cycles, and increases productivity.

Control System

The lathe is equipped with Siemens Sinumerik 808D control, providing an intuitive interface, rapid programming, and CAD/CAM compatibility that streamlines integration with modern production processes.

Cooling and Lubrication System

The integrated cooling system maintains optimal tool and workpiece temperatures, while the automatic lubrication system for gears and guides minimises component wear and reduces operating costs.

Precision and Efficiency

The CORMAK CK7135A Industrial CNC Lathe guarantees exceptional precision with a positioning repeatability of 0.006 mm. Advanced Siemens servo drives, a 3-jaw hydraulic chuck, and a turret-type tool holder ensure stability and repeatability of machining. The high spindle speed (200–3500 rpm) and the ability to configure the tool holder for 6, 8 or 12 tools allow for the execution of complex operations such as threading, grooving, and drilling with the highest surface quality.

Applications of the CNC Metal Lathe

CNC metal lathes like the CK7135A are widely used across various industries, including:

• Automotive industry: Production of precision components such as shafts, sleeves, and drive system elements.
• Machinery industry: Manufacturing of machine parts, tools, and injection moulds requiring high precision.
• Electronics industry: Machining of light alloys and metals used in electronic components.
• Serial and prototype production: Designed for small and medium production runs and prototype projects, particularly for machining medium-sized components.
