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

Q1 What is the difference between the NXX-46B and the NXX-46BL models?
The NXX-46B features a max swing over bed of Φ480mm and a max machining length of 320mm, while the NXX-46BL offers a larger Φ500mm swing and an extended 360mm machining length. The NXX-46BL also has a larger max swing over turret carriage (Φ220mm vs Φ125mm), making it better suited for larger disk-type workpieces.
Q2 What type of spindle bearing configuration does this CNC lathe use?
The spindle adopts 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, robust structural rigidity, and superior speed stability suitable for heavy-duty cutting operations.
Q3 What is the maximum rapid traverse speed of the NXX-46B/46BL?
The Z-axis achieves a rapid traverse speed of up to 30m/min, while the X-axis rapid traverse rate is 24m/min. This is made possible by high-performance servo motors directly coupled to precision pre-tensioned ball screws via flexible couplings, combined with high-rigidity linear guideways.
Q4 How fast is the tool change on the turret system?
The turret system offers an extremely fast tool-to-tool indexing time of only 0.3 seconds. Both models support up to 12 tools and use a servo rotary turret with bi-directional logic indexing (shortest path tool selection) for maximum efficiency.
Q5 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. The spindle radial and axial run-out is ≤0.003mm, and spindle facing flatness accuracy is ≤0.01mm/Φ100mm.
Q6 What safety and enclosure features does this machine include?
The machine is fully enclosed in a streamlined guarding system with superior waterproof sealing. The lightweight sliding doors are easy to operate and integrated with a safety interlock mechanism, ensuring a balance between operator safety and ergonomic convenience during daily use.
