Product Description

Structural Features
⚙️

To meet the demands of modern precision manufacturing for multi-functional integrated machining, this machine combines high-rigidity structure with advanced functional features. At its core is a heavy-duty sleeve-type spindle system with an integrated design, featuring five imported high-precision spindle bearings (three at the front and two at the rear). Driven directly by a high-power spindle servo motor, it delivers high-precision, high-rigidity output and exceptional speed stability, even under heavy-duty cutting conditions.

🏗️

The machine features a 30° slant bed design, integrated-cast from high-quality resin sand cast iron with a dense and rigid internal rib structure. This design philosophy provides exceptional static and dynamic rigidity as well as outstanding vibration damping. The slant bed layout, combined with a large-diameter chip discharge port, ensures highly efficient evacuation of chips and coolant. Both X and Z axes utilize high-rigidity linear guideways and precision pre-stretched ball screws, with servo motors directly coupled via flexible couplings, supporting rapid traverse up to 30m/min while minimizing thermal errors.

🔧

The hydraulic system is equipped with high-performance variable displacement pumps and solenoid valve groups from premium Taiwanese suppliers. Supplemented by an independent air-cooling circulation unit, the system ensures stable oil temperatures, low noise levels, and high reliability during long-term continuous operation. The tooling system offers versatile options: the standard linear gang tool post provides a simple, high-efficiency solution for rapid processing.

🌟

Turn-Mill Multi-Tasking Capability: By integrating a servo spindle and optional radial/axial servo power heads with Y-axis functionality (featuring imported precision gear transmission for high rigidity, high accuracy, and low noise), combined with infinite C-axis indexing, the machine transcends traditional turning boundaries. It can perform complex side and face drilling, tapping, milling, and engraving operations, achieving a true 'One-Setup, Complete Machining' workflow and significantly shortening the production cycle.

🛡️

The machine exterior features a modern fully-enclosed housing design, offering an elegant aesthetic combined with superior sealing performance to effectively contain coolant and chip spray. Each sliding door is engineered with a lightweight balanced design for effortless operation. Integrated with safety interlock switches, the enclosure perfectly harmonizes operational safety with user convenience.
