It adopts an integrated sleeve spindle structure, featuring imported high-precision spindle bearings in a "three-front, two-rear" layout, driven directly by a high-response spindle servo motor. This design is engineered to achieve three core objectives: ultra-high rotational accuracy, superior rigidity for heavy-duty cutting, and exceptionally stable speed performance at high RPMs, laying a solid foundation for the machine's processing capabilities.
The machine base is manufactured from a single-piece iron casting featuring a 30° slant bed design. By utilizing high-quality cast iron combined with resin sand precision casting processes and constructing a dense internal network of reinforcing ribs, the bed achieves both extreme mechanical rigidity and excellent vibration-damping characteristics. The slanted structure not only optimizes the force distribution of the machine but also provides intuitive operational convenience and high-efficiency automatic chip removal.
The X and Z axes feature high-rigidity, high-precision linear guideways and precision pre-tensioned ball screws. The servo motors are directly coupled to the ball screws via flexible couplings, ensuring zero-backlash power transmission. Equipped with a computerized automatic lubrication system, the guideways and ball screws receive forced-cycle lubrication, effectively controlling frictional heat and wear. This guarantees the system's long-term stable positioning accuracy (with minimal thermal deformation) and achieves a rapid traverse rate of up to 30 m/min.
The hydraulic station incorporates premium Taiwanese brand variable displacement pumps, motors, and solenoid valves, integrated with an air-cooled radiator to ensure low-noise and low-temperature-rise operation. The tooling system offers multiple configurations, including hydraulic or servo rotary turrets, both engineered for rapid tool changes and shortest-path tool selection. Its universal design ensures that the tool capacity is not restricted by additional functional modules (such as live tooling) or large-scale workpieces, providing exceptional adaptability.
The machine is equipped with a servo-driven spindle and an expanded live tooling system featuring Y-axis functionality for both radial and axial operations. Utilizing imported precision gear transmission, the live tools offer superior rigidity, low noise, and high operational accuracy. This configuration unlocks powerful turn-mill and engraving capabilities: while the spindle achieves 360° arbitrary indexing (C-axis), the live tooling performs complex drilling, tapping, milling, and precision engraving on both the side and end faces. Consequently, complex multi-process parts can be completed in a single setup, maximizing geometrical tolerance integrity and significantly shortening the overall manufacturing cycle.
The entire machine features a fully enclosed guard system with a streamlined, aesthetic design and superior sealing and waterproof performance. The sliding doors operate smoothly and are equipped with safety interlock devices, providing comprehensive protection while ensuring maximum operational safety and convenience. This design strictly adheres to the high standards of modern factories regarding both production environments and safety regulations.
