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 type of spindle system does the NXX-46B CNC lathe use?
The NXX-46B features an integrated cartridge spindle system with a 'front-3-rear-2' layout of imported precision-grade bearings and a direct-drive spindle servo motor, ensuring exceptional machining accuracy, rigidity, and speed stability for heavy-duty cutting operations.
Q What is the maximum spindle speed and rapid traverse rate of the NXX-46B?
The spindle speed range is 0–4000 r/min (continuously variable). The X-axis rapid traverse rate is 24 m/min and the Z-axis rapid traverse rate reaches up to 30 m/min, ensuring highly efficient machining cycles.
Q What is the difference between the NXX-46B and NXX-46BL models?
The NXX-46BL offers a larger max. swing over bed (Φ500mm vs Φ480mm), greater max. machining length (360mm vs 320mm), and a larger swing over turret carriage (Φ220mm vs Φ125mm), making it better suited for larger disk-type workpieces. The NXX-46BL also has a higher servo motor power (1.8 Kw vs 1.3 Kw) and slightly greater machine weight.
Q How fast is the tool change on the turret system?
The servo rotary turret achieves a rapid tool-to-tool indexing time of just 0.3 seconds, with bi-directional logic indexing (shortest path tool selection) for maximum efficiency. The turret holds up to 12 tools.
Q What positioning and repeatability accuracy can the NXX-46B achieve?
Both the NXX-46B and NXX-46BL achieve a repeatability accuracy of ±0.0025mm on both X and Z axes. Spindle radial and axial run-out is ≤0.003mm, and spindle facing flatness accuracy is ≤0.01mm/Φ100mm.
Q What safety and ergonomic features does the machine enclosure provide?
The machine is fully enclosed with a streamlined guarding system offering superior waterproof sealing. Lightweight sliding doors are integrated with a safety interlock mechanism, ensuring operator safety while maintaining easy access and ergonomic convenience during operation.
