Product Description
The HOLRY HR-ZLL300 is a compact, high-performance 5-axis milling head designed for precision machining of small-to-medium complex components. Engineered for seamless integration into high-speed CNC machining centers, the HR-ZLL300 features a sophisticated A/C Dual-Axis (Double Swing) structure. It is the premier choice for manufacturers requiring extreme geometric accuracy, high-speed spindle performance, and superior surface finishes in industries like medical, aerospace, and precision mold making.
Exceptional Dynamic Accuracy: Equipped with high-resolution encoders and zero-backlash reducers, the HR-ZLL300 achieves sub-micron repeatability, ensuring consistent precision in continuous 5-axis linkage operations.
Optimized for High-Speed Milling: Specifically designed to support high RPM spindles (up to 24,000 RPM), making it perfect for micro-milling, impeller machining, and intricate 3D contouring.
Compact & Rigid Design: Despite its smaller footprint compared to the ZTL series, the ZLL300 maintains high structural rigidity, effectively dampening vibrations to ensure a mirror-like surface finish.
Superior Thermal Stability: Features an advanced integrated cooling system that manages heat dissipation during prolonged high-speed runs, preventing tool center point (TCP) drift.
Global System Compatibility: Engineered for plug-and-play synchronization with major CNC controllers, including Siemens 840D, Fanuc 31i, and Heidenhain.

The HR-ZLL300 offers the perfect balance of agility and accuracy. While the larger ZTL500 is built for heavy-duty torque, the HR-ZLL300 is optimized for speed and finesse. It allows manufacturers to upgrade their existing 3-axis frames into full 5-axis powerhouses, reducing setup times and eliminating the "dead zones" common in 3+2 axis machining.
