Product Description

Structural Features
Engineered for High-Rigidity & Precision Multi-Tasking
To meet the rigorous demands of modern precision manufacturing for high rigidity, efficiency, and multi-tasking capabilities, this machine has undergone comprehensive reinforcement of its critical components.
High-Rigidity Sleeve Spindle System: Optimized for heavy-duty conditions, the core features an integrated sleeve-type spindle design. It is equipped with imported ultra-precision bearings in a "three-front, two-rear" configuration, driven directly by a high-response spindle servo motor. This synergy guarantees unparalleled accuracy retention, structural rigidity, and rotational stability during high-speed, heavy-load cutting operations.
30° Slant-Bed Foundation: The machine base is a 30° slant-bed made of high-strength cast iron, formed via the precision resin-sand casting process. The interior is reinforced with a dense, honeycomb-ribbed structure, which provides extraordinary static and dynamic rigidity while offering superior vibration damping. This design not only facilitates easier workpiece clamping and tool access but also ensures the unobstructed automatic evacuation of chips.
High-Precision Feed System: For the motion system, the X and Z axes utilize heavy-duty linear guideways known for high rigidity and precision. These are paired with precision pre-tensioned ball screws, directly coupled to the servo motors via flexible couplings to eliminate transmission loss.
Intelligent Centralized Automatic Lubrication System
An intelligent centralized automatic lubrication system provides continuous and effective forced lubrication to the guideways and ball screws. This system is key to achieving superior positioning accuracy, minimizing thermal displacement errors, and enabling rapid traverse speeds of up to 30m/min. By maintaining an optimal oil film, it significantly reduces friction and heat generation, ensuring consistent performance during high-speed operations.
Premium Hydraulic System with High-Efficiency Cooling
Hydraulic system integrates premium components from renowned Taiwanese brands, including variable displacement pumps, hydraulic motors, and solenoid valves. To ensure long-term operational stability, the system is equipped with a high-efficiency air cooler, which effectively minimizes noise levels and maintains a stable operating temperature. This combination guarantees dependable power for clamping and auxiliary movements even during intensive production cycles.
Advanced Multi-Tasking & Heavy-Duty Milling Capability
The machine is equipped with a high-performance servo spindle and a servo power turret with integrated Y-axis functionality, offering the flexibility to mount side-milling and end-milling live heads. The live tool transmission utilizes imported high-precision gear sets, achieving a perfect harmony of high rigidity, low noise, and extreme precision.
This powerful drive and execution system significantly bolsters the machine's overall structural rigidity, process stability, and indexing accuracy during multi-surface machining, delivering formidable heavy-duty cutting performance. With the spindle supporting 360° arbitrary indexing, the machine integrates side and end drilling, tapping, and milling functions. This enables the complete processing of complex, large-scale, and long-shaft workpieces in a single setup, making it the ideal choice for achieving high-level process concentration.
Hydraulic Tailstock with Programmable Quill
The machine is equipped with a hydraulic tailstock, featuring an automatic programmable quill controlled via hydraulic pressure. Designed with superior rigidity and ease of operation, it provides stable support and high-precision alignment, making it the ideal solution for the precision turning of long-shaft workpieces.
Full-Enclosure Guard with Safety Interlock
The machine features an elegantly designed full-enclosure guard, providing excellent sealing and waterproof performance. The sliding doors are engineered for smooth and effortless operation, and are integrated with a safety interlock protection system. This ensures a clean working environment and provides comprehensive protection for operators, adhering to the highest industrial safety standards.
