High-Rigidity Precision Tool: A Comprehensive Analysis of CNC Vertical Lathes

1. Advantages of CNC Vertical Lathe

The core design concept of CNC vertical lathe is to pursue the ultimate rigidity and stability. The X-axis of the machine tool innovatively adopts an over-positioning dynamic column structure and is equipped with three high-rigidity guide rails, combined with large-section high-quality bearings, to build a solid mechanical foundation. This design gives the machine tool excellent shock absorption performance and extremely high rigidity, which can not only easily cope with high-load rough processing, but also ensure excellent precision during fine processing.

Powerful processing capabilities: It can perform high-speed turning of internal and external cylindrical surfaces, conical surfaces, arcs and various complex rotary surfaces on various ferrous metals, non-ferrous metals and some non-metallic parts, achieving perfect coverage from rough processing to fine processing.

2. Structure and Design

(1). Overall design

The CNC vertical lathe adopts mechatronic design, with a compact structure, reasonable layout and modern and beautiful appearance. Safety and environmental protection are equally important: Equipped with fully enclosed protective devices, they effectively prevent coolant and chip splashing. A rear-mounted automatic chip removal system and hydraulic chuck automatic clamping function significantly enhance automation and operational safety.
Scientific Optimization: The entire machine is optimized using finite element analysis to ensure reliable performance, optimal dynamic rigidity, and smooth operation.

(2).Core Components

Heavy-Duty Base: The base utilizes a high-strength, monolithic box-type structure. The internal rib layout is precisely calculated using finite element analysis, and the material is high-density cast iron. This combination gives the base exceptional strength and excellent vibration absorption, providing a rock-solid foundation for the entire machine.

Sturdy Column: The rectangular column stands majestically atop the base. The carriage is secured to the column via three linear guides, one of which is a key guide supported at the bottom. This creates a stable three-point support structure, enabling the machine to withstand heavy cutting loads and maintain machining accuracy over time.

High-Performance Spindle: The spindle is directly driven by a high-performance servo motor. The core bearings utilize imported high-precision double-row cylindrical roller bearings and double-direction angular contact ball bearings, while the rear support also utilizes high-precision double-row cylindrical roller bearings. This precision bearing system fully meets the demands of significant axial and radial cutting forces.

Powerful Toolholder and Feed System: The CNC vertical lathe is equipped with an imported high-performance horizontal hydraulic toolholder, which not only offers high torque output and reliability, but also features a compact structure, effectively reducing interference during machining.

Precision Drive: The X and Z axis feeds are driven by servo motors and equipped with C3-grade, large-diameter precision ball screws. The preloaded design of the screws eliminates transmission backlash, ensuring high rigidity and positioning accuracy.

High-Speed ​​Guides: All axis guides utilize high-load capacity, friction-resistant roller guides, designed for efficient and precise heavy-duty cutting.
