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 key 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 max. swing over turret carriage (Φ220mm vs Φ125mm), making it better suited for larger disk-type or shaft-type workpieces. The NXX-46B features a larger X-axis travel (600mm vs 500mm) and slightly lower total power consumption (11Kw vs 12Kw).
Q
What type of spindle bearing configuration does this CNC lathe use?
The spindle uses a 'front-3-rear-2' layout of imported precision-grade bearings integrated into a cartridge spindle system. This design, combined with a direct-drive spindle servo motor, ensures exceptional machining accuracy, high rigidity, and superior speed stability — especially under heavy-duty cutting conditions.
Q
How fast is the tool change on this machine's turret system?
The turret system achieves a rapid tool-to-tool indexing time of only 0.3 seconds. It supports up to 12 tools and features bi-directional logic indexing (shortest path tool selection), 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 hydraulic components are used, and how is oil temperature managed?
The hydraulic system uses Taiwanese-branded variable displacement pumps, hydraulic motors, and solenoid valves. An independent air-cooling unit is integrated into the system to maintain stable oil temperature and ensure low-noise operation throughout continuous machining cycles.
Q
Is this CNC lathe suitable for heavy-duty machining of disk-type components?
Yes. The NXX-46B series is specifically optimized for heavy-duty machining of disk-type components. Its 30° slant bed design with dense internal reinforcement ribs provides outstanding rigidity and vibration damping. The servo rotary turret with unrestricted tool capacity for workpiece dimensions, combined with rapid traverse speeds up to 30m/min, makes it highly efficient for demanding disk-part operations.
