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 the long-bed variant, offering a larger max. swing over bed (Φ500mm vs Φ480mm), a greater max. turning diameter for disk/shaft components (Φ480/Φ220mm vs Φ380/Φ125mm), and a heavier machine weight (3100kg vs 2950kg). Both models share the same spindle bore, speed range, turret type, and repeatability accuracy specifications.
Q What type of spindle bearing configuration does this CNC lathe use?
The integrated cartridge spindle adopts a 'front-3-rear-2' layout of imported precision-grade bearings, combined with a direct-drive spindle servo motor. This ensures exceptional machining accuracy, structural rigidity, and stable high-speed performance suitable for heavy-duty cutting.
Q How fast is the tool change on the NXX-46B series turret?
The servo rotary turret achieves a rapid tool-to-tool indexing time of just 0.3 seconds. It supports bi-directional logic indexing (shortest path tool selection) and holds up to 12 tools, making it highly efficient for complex, multi-step machining operations.
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 is achieved through high-rigidity linear guideways, precision pre-tensioned ball screws, and an integrated automatic lubrication system that minimizes thermal deformation.
Q What hydraulic components are used and how is oil temperature controlled?
The hydraulic system uses Taiwanese-branded variable displacement pumps, hydraulic motors, and solenoid valves. An independent air-cooling unit is integrated to maintain stable oil temperature and ensure low-noise operation throughout continuous production cycles.
Q Is the NXX-46B series suitable for heavy-duty disk-type component machining?
Yes. The machine is specifically optimized for heavy-duty machining of disk-type components. The 30° slant bed architecture with dense internal reinforcement ribs provides superior rigidity and vibration damping, while the unrestricted tool capacity turret and rapid traverse rates up to 30m/min ensure high productivity and precision for demanding applications.
