Product Description
The HOLRY HR-ZTL500 is a heavy-duty, high-precision 5-axis milling head engineered for complex simultaneous machining. Designed for integration into large-scale CNC gantry machines and bridge-type machining centers, the HR-ZTL500 excels in high-torque operations where geometric accuracy and surface finish are critical. Featuring a robust A/C Dual-Axis (Double Swing) structure, it provides the versatility needed for intricate 3D contouring and deep-cavity milling.
Superior Rigidity for Heavy-Duty Cutting: Built with high-strength alloys and optimized damping, the ZTL500 minimizes vibration even during aggressive material removal in hardened steel or titanium.
Sub-Micron Precision: Equipped with high-resolution encoders and precision reducers, achieving exceptional repeatability and positioning accuracy for aerospace-grade tolerances.
High Load Capacity: Compared to the ZLL series, the HR-ZTL500 is specifically designed to handle larger tool diameters (HSK-A100 / BT50 compatible) and higher cutting forces.
Advanced Thermal Management: Integrated liquid cooling cycles maintain constant spindle temperatures, preventing thermal expansion and ensuring long-term stability during 24/7 production cycles.
Seamless CNC Integration: Fully compatible with industry-leading controllers including Siemens 840D, Fanuc 31i, and Heidenhain TNC 640.
