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.
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.
