Product Description

Machine Structural Features

Core Spindle System
Heavy-Duty Integral Sleeve Spindle

Engineered for sustained heavy-cutting conditions, the spindle features a robust integral sleeve-type design. It integrates a "Three-Front, Two-Rear" configuration of imported precision bearings, powered by a rear-mounted servo motor. This combination delivers a consistent output of high speed, high precision, and exceptional rigidity.

Robust Bed Architecture

Utilizing a 30° slant-bed layout, the machine base is cast from high-quality resin-sand cast iron. The internal structure features a dense reinforcement ribbing system, delivering a superior combination of high rigidity, exceptional vibration damping, ergonomic operator convenience, and efficient automatic chip evacuation.

High-Speed Precision Feed System
High-Performance Linear Motion System

The X and Z axes are equipped with high-rigidity, heavy-duty linear guideways and precision pre-tensioned ball screws. Driven by direct-coupled servo motors and supported by an automatic forced lubrication system, the axes achieve rapid traverse speeds of up to 30 m/min while ensuring superior positioning accuracy and minimal thermal deformation.

Advanced Y-Axis Servo Power Turret

Equipped with a high-precision Y-axis box-way dual-side servo power turret, this system offers exceptional reliability and low failure rates. It supports rapid, nearest-path tool indexing for maximum efficiency. The turret disk is designed for flexible tool loading, unaffected by additional live tool attachments or workpiece dimensions, ensuring superior adaptability for diverse machining tasks.

Top-Tier Turn-Mill Capabilities
Integrated Multi-Tasking Machining Cell

This represents the ultimate highlight of the machine. By integrating rear-mounted servo main and sub-spindles, a Y-axis servo power turret, and imported precision gear-driven live tooling (for both radial and axial milling), we have built a complete, high-performance turn-mill unit.

💡 Multi-tasking Efficiency: This system significantly enhances machining rigidity, thermal stability, and indexing precision. It supports infinite C-axis indexing and dynamic workpiece handover (on-the-fly) between main and sub-spindles, effectively eliminating secondary setup errors. Complex geometries, large components, and parts with strict concentricity requirements can be completed—from turning and milling to drilling and tapping—in a single setup. This ensures maximum machining accuracy while drastically shortening the overall manufacturing cycle.
Reliable Auxiliary Systems
Advanced Hydraulic & Safety Systems

The hydraulic station utilizes high-performance variable displacement pumps and core components from top-tier brands, equipped with an integrated air-cooling system. This ensures exceptionally quiet operation and precise oil temperature control even during extended shifts.

Full Safety Enclosure

The machine features a stylish, fully enclosed protective housing that is completely waterproof and chip-proof. For maximum operator protection, the sliding doors are equipped with safety interlocks, ensuring a secure and user-friendly working environment.
