CNC Lathe with Slant Bed CK400X750
The CNC Lathe with Slant Bed CK400X750 is an advanced industrial machine designed for precise metal machining. Equipped with modern Siemens Sinumerik 808D control and a robust construction, it ensures reliability and high performance in demanding production environments.
Main Advantages of the CNC Lathe CK400X750
The CNC Lathe CK400X750 has been designed to meet the needs of modern manufacturing facilities. Its key advantages include both advanced technological solutions and practical benefits for the operator, translating into machining efficiency and quality. Below are the detailed advantages of the machine:
- High machining precision – the slant bed and advanced CNC control ensure accuracy even for complex parts, minimizing dimensional deviations.
- Increased efficiency – maximum feed rates on the Z/X axes (10,000/8,000 mm/min) and a wide spindle speed range (200–4000 rpm) enable fast and effective machining.
- Durable construction – the solid 3,300 kg structure guarantees stability and vibration reduction, which is crucial when machining large components.
- Intuitive control – the Siemens Sinumerik 808D system with a graphical interface simplifies programming and operation, even for less experienced users.
- Versatility of applications – the machine allows the machining of various materials such as steel, aluminium, or metal alloys, in both small-batch and serial production.
- Economical operation – the automatic lubrication system and efficient cooling unit reduce component wear and maintenance costs.
- Flexible configuration – optional upgrades such as Siemens Sinumerik 828D control or driven tools enhance the machine’s functionality.
Design and Technology of the CNC Lathe
Slant Bed for Maximum Stability
The industrial CNC lathe CK400X750 features a slant bed that provides excellent rigidity and efficient chip evacuation. This design minimizes mechanical and thermal deformation, resulting in machining precision and extended machine life.
Spindle and Drive System
The spindle with a bore of 52 mm and a 210 mm chuck is driven by a 7.5 kW motor. The wide spindle speed range (200–4000 rpm) allows adaptation of cutting parameters to various materials — from light alloys to hardened steels.
Turret Head and Tool System
The 12-position turret head enables rapid tool changes with tool sizes of 12x25 mm, increasing production flexibility and minimising downtime. The automatic lubrication system for guides and gears ensures smooth operation and reduces mechanical wear.
Cooling System and Hydraulic Tailstock
The efficient cooling system prevents overheating of the workpiece and tool, which is crucial during long-term serial machining. The hydraulic tailstock with a sleeve diameter of 62 mm, stroke of 80 mm, and taper MK4 ensures stable clamping of parts up to 750 mm in length.
Precision and Performance
The CNC Lathe for Metal CK400X750 combines advanced technology with a solid construction, ensuring exceptional precision and efficiency. The slant bed reduces vibrations, allowing smooth surfaces and accurate dimensions to be achieved. The maximum turning diameter over the bed is 400 mm, and over the carriage 210 mm, enabling machining of a wide range of components. Fast feed rates and flexible control ensure efficiency both in single-piece and batch production.
Applications of the CNC Lathe
The CK400X750 CNC Lathe is an ideal solution for production plants requiring reliable metal-cutting machines. It is used in:
- Automotive industry – for the production of precision components such as shafts, bushings, and suspension elements.
- Machinery industry – for machining machine parts including gears, drive shafts, and housings.
- Small and medium workshops – its versatility and simple operation make it suitable for smaller enterprises.
- Serial and single production – machine flexibility allows both large-batch manufacturing and individual parts with high requirements.
