Product Description

Key Structural Features

The unit adopts a professional-grade sleeve spindle with a monolithic design, supported by a high-precision 3-front/2-rear bearing configuration. Coupled with a rear-drive servo system, it maintains exceptional stiffness and operational stability during heavy loads. The 65° slant bed, engineered from high-grade resin-sand casting with an intensive ribbed-plate architecture, combines superior anti-vibration properties with an ergonomic workflow for seamless chip disposal.
Precision Feed System & Tooling
High-Speed Feed Mechanism: Each axis features a direct-drive configuration with servo motors and pre-tensioned precision ball screws. Integrated with high-rigidity linear guideways and an automatic lubrication system, it achieves a 30 m/min rapid traverse and micron-level positioning accuracy while effectively minimizing thermal displacement.
T-Type Gang Tooling: The unique T-style gang tool post supports versatile multi-tool configurations, ensuring rapid and seamless tool indexing for maximized throughput.
Synchronized Twin-Spindle & Dual-Gang-Tooling
The synchronized operation of twin spindles and dual gang tool posts enables dynamic part hand-off (re-gripping) between the main and sub-spindles. This allows for complete multi-surface machining in a single setup, significantly reducing geometric tolerances and ensuring superior part consistency.
Hydraulic & Cooling Performance
Equipped with premium Taiwanese variable pumps and solenoid valves, the system features an integrated air cooler to guarantee quiet operation and optimal oil temperature stability during prolonged cycles.
The machine features a fully enclosed protective housing with a sleek, minimalist aesthetic and superior waterproof sealing. The lightweight sliding doors are integrated with safety interlocks, ensuring full compliance with high-standard modern workshop requirements for operator safety and environmental cleanliness.
