This equipment is engineered with a high-performance sleeve-type spindle system specifically designed to meet the rigorous demands of high-precision, high-rigidity, and heavy-duty machining. Featuring a monoblock sleeve structure, the spindle is integrated with imported precision-grade bearings in a "three-front, two-rear" configuration. Driven directly by a high-power spindle servo motor, the system achieves exceptional dynamic rigidity, superior rotational accuracy, and sustained stability at high speeds. This robust architecture provides a reliable guarantee for both heavy-duty cutting and high-precision finishing operations.
The machine features a durable monoblock cast iron base and a 30° slant bed design, precision-molded using premium resin sand casting technology. The interior is reinforced with a dense rib-plate configuration, delivering exceptional static and dynamic rigidity along with outstanding vibration-dampening characteristics. This slant bed layout not only enhances operator visibility and ergonomic accessibility but also facilitates the natural gravity-fed evacuation of chips and coolant. This significantly boosts chip disposal efficiency and simplifies routine operation and maintenance.
The linear motion system seamlessly integrates high rigidity, precision, and velocity. The X and Z axes are directly coupled to precision pre-tensioned ball screws via high-performance servo motors and flexible couplings. Combined with high-rigidity precision linear guideways, this architecture effectively eliminates transmission backlash. Equipped with an intelligent automated lubrication system, the guideways and ball screws receive precise, timed lubrication and cooling. This enables rapid traverse speeds of up to 30 m/min while ensuring superior positioning accuracy, minimal thermal deformation, and the long-term stability required for consistent batch production.
The hydraulic station incorporates premium variable displacement pumps, hydraulic motors, and solenoid valves from trusted suppliers, integrated with a high-efficiency air-cooled heat exchanger. This ensures quiet operation, stable oil temperatures, and exceptional reliability, providing a consistent power source for all auxiliary functions. The machine is equipped with an advanced servo spindle and a servo-driven power turret with Y-axis functionality. Optional high-precision side and end-milling live tool heads are available, featuring an imported precision gear transmission system. This robust design offers superior rigidity, low operating noise, and high indexing accuracy, significantly enhancing the machine's multi-tasking capabilities and heavy-duty cutting performance. Furthermore, the spindle features full 360° arbitrary indexing (C-axis functionality). This allows complex workpieces to undergo side and end-face drilling, tapping, and milling in a single setup, drastically shortening process cycles while maximizing machining efficiency and precision.
The machine exterior features a streamlined, fully enclosed protective enclosure with a modern design that provides exceptional waterproof and chip-proof sealing. The sliding safety doors are engineered with lightweight materials and a balanced design, ensuring effortless opening and closing. Equipped with reliable safety interlocking devices, the enclosure guarantees a secure and convenient operating environment while maintaining a clean and professional workspace.
