Product Description
The HOLRY HR-ZLL500 is a flagship-grade, industrial-scale CNC 5-axis milling head engineered for heavy-duty, high-precision simultaneous machining. Specifically developed for large-scale gantry machining centers and bridge-type machines, the HR-ZLL500 represents the pinnacle of HOLRY’s "Double Swing" (A/C axis) technology. It is the premier choice for manufacturers handling massive, complex workpieces in the aerospace, energy, and heavy-duty mold industries where extreme torque and sub-micron stability are non-negotiable.
Exceptional Heavy-Duty Performance: Built with reinforced structural casting, the ZLL500 is designed to handle maximum cutting forces, making it ideal for tough materials like titanium, Inconel, and hardened steel alloys.
Maximum Tooling Versatility: Optimized for HSK-A100 and BT50 interfaces, allowing for larger tool diameters and deeper material removal rates compared to smaller models.
Superior Positioning Accuracy: Featuring high-resolution absolute encoders and high-torque precision reducers, the HR-ZLL500 ensures precise A/C axis synchronization for flawless 3D surface finishing.
Integrated Liquid Cooling System: A high-efficiency thermal management circuit runs through the spindle and axis motors, ensuring consistent accuracy and preventing thermal expansion during 24/7 continuous operation.
Universal CNC Synchronization: Engineered for seamless integration with high-end controllers including Siemens 840D, Fanuc 31i, and Heidenhain TNC 640.

The HR-ZLL500 is the ultimate upgrade for manufacturers scaling up their production capabilities. While the HR-ZLL300 and ZTL420 focus on agility and medium-range work, the ZLL500 is built for pure power and uncompromising rigidity. It transforms your existing large-scale machine frame into a multi-axis powerhouse capable of finishing complex geometries in a single setup, drastically reducing lead times and labor costs.
