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 the machine with exceptional static and dynamic rigidity as well as outstanding vibration damping, creating a stable platform for precision machining. The slant bed layout, combined with a large-diameter chip discharge port, ensures highly efficient evacuation of chips and coolant while optimizing workpiece setup and operator ergonomics.

The motion system is engineered for high-speed and high-precision performance. Both X and Z axes utilize a combination of high-rigidity linear guideways and precision pre-stretched ball screws. The servo motors are directly coupled to the ball screws via flexible couplings. Integrated with an automatic intelligent lubrication system, the guideways and screws receive optimal lubrication and cooling even during high-speed operations (up to 30m/min rapid traverse), effectively minimizing thermal errors and ensuring superior positioning and repeatability.

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.

The defining highlight of this machine lies in its powerful 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 the 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.

Frequently Asked Questions

What is the key difference between the NXX-46CY and the NXX-46BCY models?

The NXX-46CY features a gang-type tooling system with a max swing diameter of Φ400mm and up to 4–5 tool capacity, making it ideal for high-efficiency simple part production. The NXX-46BCY is a larger, more capable model with a Φ550mm swing diameter, servo rotary turret (8–12 tools), greater axis travel, and higher motor power — suited for more complex and heavier workpieces.

What operations can the turn-mill multi-tasking capability perform?

Thanks to the integrated servo spindle, optional radial/axial servo power heads with Y-axis functionality, and infinite C-axis indexing, the machine can perform turning, drilling, tapping, milling, and engraving in a single setup. This "One-Setup, Complete Machining" capability significantly reduces production cycle times and improves part accuracy.

How does the 30° slant bed design benefit machining performance?

The 30° slant bed, cast from high-quality resin sand cast iron with a dense internal rib structure, provides exceptional static and dynamic rigidity along with outstanding vibration damping. The slant layout also facilitates efficient chip and coolant evacuation via the large-diameter discharge port, while improving operator ergonomics and workpiece accessibility.

What is the maximum rapid traverse speed and how is thermal error controlled?

Both X and Z axes support rapid traverse speeds of up to 24m/min and 30m/min respectively, while the Y-axis reaches 15m/min. Thermal errors are minimized through the use of precision pre-stretched ball screws, flexible-coupled servo motors, and an automatic intelligent lubrication system that ensures optimal lubrication and cooling during high-speed operations.

What are the spindle accuracy and repeatability specifications?

The spindle radial and axial run-out is ≤0.003mm, flatness accuracy is ≤0.01mm/Φ100, and the live tool spindle taper run-out is ≤0.006mm. Both X and Z axis repeatability accuracy is ±0.0025mm, and the C-axis (spindle) repeatability is 0.01mm — ensuring consistent precision across high-volume production runs.

What safety and operator convenience features does the machine enclosure offer?

The machine features a modern fully-enclosed housing with superior sealing performance to contain coolant and chip spray. Each sliding door uses a lightweight balanced design for easy, effortless operation. Safety interlock switches are integrated throughout, ensuring that operational safety and user convenience are maintained simultaneously during all machining processes.
