Structural Characteristics
High-Performance Sleeve-Type Spindle System

This equipment is engineered with a high-performance sleeve-type spindle system specifically designed to meet the rigorous demands of high-precision, high-rigidity, and heavy-duty machining.

Featuring a monoblock sleeve structure, the spindle is integrated with imported precision-grade bearings in a "three-front, two-rear" configuration. Driven directly by a high-power spindle servo motor, the system achieves exceptional dynamic rigidity, superior rotational accuracy, and sustained stability at high speeds. This robust architecture provides a reliable guarantee for both heavy-duty cutting and high-precision finishing operations.

Monoblock Cast Iron Base & 30° Slant Bed Design

The machine features a durable monoblock cast iron base and a 30° slant bed design, precision-molded using premium resin sand casting technology. The interior is reinforced with a dense rib-plate configuration, delivering exceptional static and dynamic rigidity along with outstanding vibration-dampening characteristics.

This slant bed layout not only enhances operator visibility and ergonomic accessibility but also facilitates the natural gravity-fed evacuation of chips and coolant. This significantly boosts chip disposal efficiency and simplifies routine operation and maintenance.

High-Performance Linear Motion System

The linear motion system seamlessly integrates high rigidity, precision, and velocity. The X and Z axes are directly coupled to precision pre-tensioned ball screws via high-performance servo motors and flexible couplings. Combined with high-rigidity precision linear guideways, this architecture effectively eliminates transmission backlash.

Equipped with an intelligent automated lubrication system, the guideways and ball screws receive precise, timed lubrication and cooling. This enables rapid traverse speeds of up to 30 m/min while ensuring superior positioning accuracy, minimal thermal deformation, and the long-term stability required for consistent batch production.

Advanced Hydraulics & Multi-Axis Machining Excellence

The hydraulic station incorporates premium variable displacement pumps, hydraulic motors, and solenoid valves from trusted suppliers, integrated with a high-efficiency air-cooled heat exchanger. This ensures quiet operation, stable oil temperatures, and exceptional reliability, providing a consistent power source for all auxiliary functions.

The machine is equipped with an advanced servo spindle and a servo-driven power turret with Y-axis functionality. Optional high-precision side and end-milling live tool heads are available, featuring an imported precision gear transmission system. This robust design offers superior rigidity, low operating noise, and high indexing accuracy, significantly enhancing the machine's multi-tasking capabilities and heavy-duty cutting performance.

Furthermore, the spindle features full 360° arbitrary indexing (C-axis functionality). This allows complex workpieces to undergo side and end-face drilling, tapping, and milling in a single setup, drastically shortening process cycles while maximizing machining efficiency and precision.

Modern Aesthetic & Enhanced Safety Guarding

The machine exterior features a streamlined, fully enclosed protective enclosure with a modern design that provides exceptional waterproof and chip-proof sealing. The sliding safety doors are engineered with lightweight materials and a balanced design, ensuring effortless opening and closing.

Equipped with reliable safety interlocking devices, the enclosure guarantees a secure and convenient operating environment while maintaining a clean and professional workspace.

Frequently Asked Questions
What is the difference between the NXX-46E, NXX-46EY, and NXX-52DEY models?
The primary differences lie in machining capacity, axis configuration, and power. The NXX-46E is a standard model with X/Z axes and a 5.5 kW main motor. The NXX-46EY adds Y-axis functionality (±55 mm travel) and a more powerful 7.5 kW motor, enabling off-center milling and drilling. The NXX-52DEY offers the largest machining envelope with a 400 mm Z-axis travel, 11 kW main motor, and a tailstock, making it ideal for longer shaft-type workpieces.
What is the advantage of the 30° slant bed design?
The 30° slant bed design improves operator ergonomics and visibility, while allowing chips and coolant to drain naturally by gravity. This significantly reduces chip accumulation on the guideways, extends machine life, and simplifies daily maintenance. The design also contributes to better static and dynamic rigidity compared to flat-bed configurations.
What types of live tooling are supported, and what is the maximum live tool speed?
All three models support live tooling. The NXX-46E uses ER25 toolholders, while the NXX-46EY and NXX-52DEY support both ER25 and ER32 holders with Y-axis capability. The maximum live tool speed across all models is 3,000–6,000 r/min, with a maximum clamping capacity of Φ16 mm (NXX-46E) or Φ16/Φ20 mm (NXX-46EY and NXX-52DEY).
Does the machine support C-axis (full 360° spindle indexing) for complex part machining?
Yes. All models feature full 360° arbitrary spindle indexing (C-axis functionality). This enables complex workpieces to undergo side-face and end-face drilling, tapping, and milling in a single setup — eliminating the need for secondary operations, reducing cycle times, and improving overall machining precision and efficiency.
What is the positioning and repeatability accuracy of the machine?
The machine achieves a spindle radial and axial run-out accuracy of ≤0.003 mm, spindle face flatness of ≤0.01 mm/Φ100, and live tool taper run-out of ≤0.006 mm. The X and Z axis repeatability accuracy is ±0.0025 mm, and the C-axis repeat positioning accuracy is 0.01 mm — meeting the requirements of high-precision batch production.
What hydraulic components are used, and how is thermal stability maintained?
The hydraulic station uses premium variable displacement pumps, hydraulic motors, and solenoid valves sourced from trusted suppliers. An integrated high-efficiency air-cooled heat exchanger maintains stable oil temperatures during continuous operation, ensuring quiet, reliable performance and consistent auxiliary function output without thermal drift.
