Product Description

Structural Features

This series of machines focuses on reinforcing the rigidity, precision, and load-bearing capacity of core components. It features a monoblock sleeve-type spindle with a "three-front, two-rear" imported precision bearing layout. Driven by a high-performance servo motor, the spindle system ensures high-precision rotational accuracy, high-rigidity support, and consistent speed output to meet heavy-duty machining demands.

The bed is constructed from a one-piece cast iron structure with a 30° slant bed design, utilizing premium cast iron and resin sand casting technology. The interior is reinforced with a dense rib-plate configuration, providing exceptional structural rigidity and superior vibration dampening. This design also offers excellent visibility and accessibility for the operator while facilitating natural chip evacuation.

X/Z-Axis Guidance and Drive System: The X/Z axes utilize high-rigidity, high-precision linear guideways paired with precision pre-stretched ball screws. These are directly coupled to the servo motors via flexible couplings. Supported by a computer-controlled automatic centralized lubrication system, the guideways and ball screws receive forced lubrication to effectively guarantee high positioning accuracy, suppress thermal deformation, and achieve rapid traverse rates of up to 30 m/min.

Hydraulic System: The core of the hydraulic station integrates premium Taiwanese components, including a variable displacement pump, high-torque hydraulic motor, and electromagnetic valves. The addition of a forced air-cooling module ensures smooth, quiet operation and effective oil temperature control for consistent performance.

Turn-Mill & Power Turret: The machine features a servo-driven spindle synchronized with a servo power turret, which can be expanded with radial (side) or axial (end) live tooling heads. These heads utilize imported precision gear transmissions, delivering superior rigidity, minimal noise, and high operational accuracy.

Machining Performance: This configuration significantly enhances machining rigidity, operational stability, and indexing accuracy, unleashing exceptional heavy-duty cutting performance. With 360° arbitrary spindle indexing (C-axis) and multi-functional capabilities (drilling, tapping, and milling on both side and end faces), complex and large-scale workpieces can be processed with high efficiency in a single setup (Done-in-One).

The entire machine is encased in a fully enclosed protection system featuring a sophisticated industrial design with excellent sealing and waterproof performance. The sliding operator doors are engineered for effortless movement, providing smooth and easy access. For maximum operator protection, the system is equipped with a reliable safety interlock, ensuring a secure and user-friendly working environment that meets rigorous safety standards.

Frequently Asked Questions
Q What is the key difference between the NXX-46E, NXX-46EY, and NXX-52DEY models?
The NXX-46E is a compact, high-speed turn-mill center suited for disk and short shaft parts. The NXX-46EY adds a Y-axis (±55mm travel) and enhanced live tooling (ER25/ER32) for off-center milling and complex features. The NXX-52DEY offers the largest swing (Φ480mm), longest Z-travel (550mm), highest main motor power (11kW), and includes a tailstock, making it ideal for large, heavy-duty shaft workpieces requiring full 5-axis-style Done-in-One machining.
Q What does the 30° slant bed design offer compared to a flat bed CNC lathe?
The 30° slant bed design provides superior chip evacuation, as chips fall away from the cutting zone by gravity rather than accumulating on guideways. It also improves operator ergonomics and visibility, reduces thermal deformation effects, and enhances the structural rigidity of the machine — all contributing to better surface finish and longer tool life during heavy-duty cutting operations.
Q What types of machining operations can the servo power turret perform?
The servo power turret supports a wide range of operations beyond standard turning, including radial (side-face) drilling and milling, axial (end-face) drilling, tapping up to M10–M14, and milling with ER25/ER32 live tooling. Combined with C-axis 360° arbitrary indexing, it enables complete complex part machining — including off-center holes, keyways, and contoured surfaces — in a single setup without re-clamping.
Q How does the centralized automatic lubrication system benefit machine performance and longevity?
The computer-controlled automatic centralized lubrication system delivers precisely timed, forced lubrication to all linear guideways and ball screws. This minimizes friction-induced wear, suppresses thermal deformation from heat buildup, and maintains consistent positioning accuracy over long production runs. It also reduces manual maintenance requirements and extends the service life of critical motion components significantly.
Q What safety features are integrated into the machine's enclosure design?
The machine features a fully enclosed protection system with high-grade sealing and waterproofing to contain coolant, chips, and mist. The sliding operator doors are designed for smooth, low-effort operation and are equipped with a safety interlock system that prevents the machine from operating when the door is open. This ensures compliance with international machine safety standards and provides a secure working environment for operators during all phases of operation.
Q What is the spindle repeatability accuracy, and what precision levels can be achieved?
All three models achieve X/Z-axis repeatability accuracy of ±0.0025mm, spindle radial/axial run-out of ≤0.003mm, flatness accuracy of ≤0.01mm/Φ100mm, and live tool spindle taper run-out of ≤0.006mm. The C-axis (spindle indexing) repeatability is 0.01°. These specifications make the NXX series suitable for precision aerospace, automotive, and hydraulic component manufacturing where tight tolerances are critical.
