CNC Slant Bed Lathe CK400x500

CNC Slant Bed Lathe CK400x500 is an advanced industrial machine designed for precise metal machining. Owing to its rigid construction and modern control systems such as Siemens Sinumerik 808D, it provides high efficiency and reliability in demanding production environments.

Main advantages of the CNC lathe CK400x500

• High machining precision – the slant-bed structure and advanced CNC control ensure accuracy even with complex parts.
• Performance and speed – maximum feed rates of axes Z/X (10 000 / 8 000 mm/min) and a wide spindle-speed range (200–4 000 rpm) guarantee efficient production.
• Durable construction – the massive 3 100 kg structure ensures stability and minimises vibrations during operation.
• Intuitive operation – the Siemens Sinumerik 808D system with graphical interface simplifies programming and daily use.
• Versatility – suitable for machining various materials including steel, aluminium and metal alloys.
• Cost-effective design – the automatic lubrication system and efficient cooling unit reduce maintenance and operating costs.

Design and technology of the CNC lathe

Slant-bed construction

CK400x500 CNC lathe has been designed with a slant-bed structure providing greater rigidity and chip evacuation efficiency compared to traditional flat-bed designs. Such construction minimises thermal and mechanical deformation, resulting in long-term dimensional accuracy during machining.

Spindle and drive

The spindle with a bore of 52 mm and chuck 210 mm is driven by a 7.5 kW motor, enabling effective machining of both small and larger components. The spindle-speed range 200–4 000 rpm allows adjusting parameters to different materials and operations.

Turret head

The 12-position turret head enables fast tool change for tools 12 × 25 mm, which increases flexibility and shortens downtime. The automatic lubrication system for gears and guideways ensures smooth motion and extends the service life of components.

Cooling system and hydraulic tailstock

The lathe is equipped with an efficient cooling system that prevents overheating of the workpiece and tools, which is essential for serial production. The hydraulic tailstock with a sleeve diameter of 62 mm and travel of 80 mm (MK4 taper) provides stable support for workpieces up to 500 mm in length.

Precision and efficiency of operation

Industrial CNC lathe CK400x500 stands out for its precision thanks to the use of modern CNC control systems and a robust construction. The slant-bed design reduces vibrations, resulting in smooth surfaces and accurate dimensions of machined components. The maximum turning diameter over the bed is 400 mm, and over the cross-slide 210 mm, which allows machining of various parts. Fast feed rates and a wide spindle speed range ensure high productivity, particularly in serial production.

Applications of the CNC metal lathe

CNC metal lathe CK400x500 is used in production plants specialising in cutting processes. It is the perfect choice for:

• Automotive industry – production of shafts, bushings and other precision components.
• Machinery industry – machining of machine parts such as gears and drive shafts.
• Small and medium workshops – versatility and ease of use allow for quick implementation in smaller enterprises.
• Serial and unit production – machine flexibility enables both large batch manufacturing and single-piece machining.
