Product Description

Machine Structural Features
Our high-rigidity cartridge-type spindle system features an integrated monoblock structure, paired with a precision-grade imported bearing layout in a 'front-3-rear-2' configuration. Driven by a dedicated rear-mounted servo motor, it delivers exceptional speed stability and heavy-duty cutting capability, making it ideal for high-precision machining scenarios. The base is constructed from high-strength cast iron using a resin-sand casting process. The 45° inclined bed design, combined with a dense reinforcement rib layout, significantly enhances structural rigidity and vibration dampening while optimizing ergonomic operation and chip evacuation efficiency.
Each X/Z axis is directly coupled with pre-tensioned ball screws via flexible couplings and driven by high-performance servo motors. Combined with high-precision linear guideways and an intelligent centralized lubrication system, the machine achieves high-speed (30m/min rapid traverse) and high-precision positioning with superior thermal compensation. The T-type gang tooling module supports versatile tool configurations, ensuring ultra-fast indexing and interference-free operation.
The innovative twin-spindle and twin-gang configuration supports simultaneous machining and dynamic synchronization between the main and sub-spindles. By completing all processes in a single setup, the system effectively guarantees superior geometric tolerances and eliminates cumulative errors from secondary handling.
The hydraulic unit incorporates a famous Taiwan-branded variable displacement pump and a high-efficiency air-cooling system, ensuring ultra-quiet operation and stable temperature control during continuous production.
The machine features a fully enclosed guarding structure with a modern, aesthetic design and superior sealing performance. The lightweight sliding doors are equipped with a safety interlock mechanism, perfectly balancing operational convenience with workplace safety.
