China Suppliers NXX-46CY Slant Bed CNC Turn-Mill Center with Live Tooling - High-Performance Factory Solution
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.

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.
⭐
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
Q
What is the key difference between the NXX-46CY and the NXX-46BCY model?
The NXX-46BCY is the larger-capacity variant, offering a greater max. swing diameter over the bed (Φ550 vs. Φ400), longer Z-axis travel (360mm vs. 260mm), a servo rotary turret with up to 12 tool positions (vs. 4–5 in gang-type), and higher servo motor power (2.4Kw vs. 1.3Kw), making it better suited for heavier and more complex workpieces.
Q
What machining operations can be performed with the live tooling system?
The integrated live tooling system — combined with the Y-axis and infinite C-axis indexing — enables the machine to perform drilling, tapping (up to M10), milling, and engraving on both radial and axial faces of the workpiece. This allows complex multi-side machining to be completed in a single setup without re-clamping.
Q
What is the significance of the 30° slant bed design?
The 30° slant bed, cast from high-quality resin sand cast iron with an internal rib structure, provides superior static and dynamic rigidity along with excellent vibration damping. The angled layout also facilitates efficient chip and coolant evacuation through the large-diameter discharge port, while improving operator ergonomics and workpiece accessibility.
Q
How does the machine ensure long-term positioning accuracy?
Both X and Z axes use high-rigidity linear guideways paired with precision pre-stretched ball screws directly coupled to servo motors. An automatic intelligent lubrication system continuously lubricates and cools the guideways and screws during high-speed operation, minimizing thermal errors and maintaining a repeatability accuracy of ±0.0025mm on both axes.
Q
What are the safety and operational features of the machine enclosure?
The machine is equipped with a modern fully-enclosed housing that effectively contains coolant splash and chip spray. Each sliding door uses a lightweight balanced design for easy one-hand operation, and all doors are integrated with safety interlock switches that prevent accidental operation when the enclosure is open, ensuring both operator safety and machining reliability.
Q
What are the hydraulic system specifications and how is oil temperature managed?
The hydraulic system uses high-performance variable displacement pumps and solenoid valve groups sourced from premium Taiwanese suppliers. An independent air-cooling circulation unit is incorporated to maintain stable oil temperatures during prolonged continuous operation, resulting in low noise levels, reduced wear, and high system reliability over the machine's service life.
