Product Description

Machine Structural Features
Dedicated to the high-performance CNC machining sector, we proudly introduce this precision machine tool equipped with an integrated cartridge spindle system. The spindle incorporates a 'front-3-rear-2' layout of imported precision-grade bearings, coupled with a direct-drive spindle servo motor. This configuration guarantees exceptional machining accuracy, robust structural rigidity, and superior speed stability, meeting the stringent requirements of heavy-duty cutting operations. The machine bed is cast from premium-grade cast iron using a resin-sand molding process. Featuring a 30° slant bed architecture and a dense internal reinforcement rib layout, it delivers outstanding overall rigidity and vibration damping, while simultaneously optimizing ergonomic accessibility and chip evacuation efficiency.
The X and Z axes are driven by high-performance servo motors direct-coupled to precision pre-tensioned ball screws via flexible couplings. In combination with high-rigidity, high-precision linear guideways and an integrated computerized automatic lubrication system for forced oiling of both guides and screws, the system achieves rapid traverse speeds up to 30m/min. This ensures precise positioning with minimal thermal deformation during high-speed operations.
Hydraulic system incorporates Taiwanese-branded variable displacement pumps, hydraulic motors, and solenoid valves, integrated with an independent air-cooling unit to ensure low-noise operation and stable oil temperature control. The turret system offers options for hydraulic or servo-driven rotary turrets, featuring robust structural rigidity and bi-directional logic indexing (shortest path tool selection). With a rapid tool-change time of only 0.3–0.5 seconds and a tool capacity unrestricted by workpiece dimensions, it is particularly optimized for the heavy-duty machining of disk-type components.
The entire machine is encased in a fully enclosed guarding system with streamlined aesthetics and superior waterproof sealing. The lightweight sliding doors operate effortlessly and are integrated with a safety interlock mechanism, ensuring a perfect balance between operator safety and ergonomic convenience.

Frequently Asked Questions
Q What is the difference between the NXX-46B and NXX-46BL models?
The NXX-46BL is an extended-capacity variant. Key differences include a larger Max. Swing Over Bed (Φ500 vs Φ480), greater Max. Machining Length (360mm vs 320mm), a larger Max. Swing Over Turret Carriage (Φ220 vs Φ125), and a higher X/Z Axis Servo Motor Power (1.8Kw vs 1.3Kw). The NXX-46BL is better suited for machining larger disk-type and shaft-type components.
Q What type of spindle bearing configuration does the NXX-46B series use?
The NXX-46B series uses an integrated cartridge spindle system with a 'front-3-rear-2' layout of imported precision-grade bearings. Combined with a direct-drive spindle servo motor, this configuration ensures exceptional machining accuracy, structural rigidity, and superior speed stability up to 4,000 r/min.
Q How fast is the tool-change speed on the NXX-46B series?
The NXX-46B series features an extremely fast tool-change time of only 0.3 seconds (tool-to-tool indexing time). The servo rotary turret supports bi-directional logic indexing (shortest path tool selection), accommodating up to 12 tools, significantly reducing non-cutting time and improving overall productivity.
Q What is the repeatability accuracy of the X and Z axes?
Both the X-axis and Z-axis achieve a repeatability accuracy of ±0.0025mm on both the NXX-46B and NXX-46BL models. This high precision is achieved through the combination of precision pre-tensioned ball screws, high-rigidity linear guideways, and an automatic forced lubrication system.
Q What are the advantages of the 30° slant bed design?
The 30° slant bed architecture, cast from premium-grade cast iron using a resin-sand molding process with a dense internal reinforcement rib layout, provides outstanding overall rigidity and vibration damping. It also improves chip evacuation efficiency and enhances ergonomic accessibility for operators, making it ideal for heavy-duty and high-precision turning operations.
Q Is the hydraulic system on the NXX-46B series reliable for continuous production?
Yes. The hydraulic system incorporates Taiwanese-branded variable displacement pumps, hydraulic motors, and solenoid valves, integrated with an independent air-cooling unit. This design ensures low-noise operation and stable oil temperature control, making it highly reliable for continuous, high-intensity production environments.
