Frequently Asked Questions
Q
What is the main difference between the NXX-26AS and the NXX-36AS models?
The NXX-26AS features a 65° slant bed angle, a max swing diameter of Φ400mm, a spindle bore of Φ36mm, and a total power capacity of 22 kW, making it ideal for smaller, high-speed precision parts. The NXX-36AS offers a 45° slant bed, a larger max swing diameter of Φ500mm, a spindle bore of Φ45mm, and supports heavier workpieces up to 4,600 kg, suited for larger-diameter turning applications.
Q
What does the synchronized twin-spindle and dual-gang-tooling system offer in terms of productivity?
The synchronized twin-spindle and dual gang tool post system enables automatic part transfer (re-gripping) between the main and sub-spindles without manual intervention. This allows complete multi-surface machining in a single setup, dramatically reducing cycle times, minimizing geometric tolerances, and ensuring consistent part quality across high-volume production runs.
Q
How does the T-Type Gang Tooling system benefit machining operations?
The T-Type Gang Tooling system supports versatile multi-tool configurations on a single tool post, accommodating up to 16 tools (OD tools at 20×20mm and boring bars up to Φ25mm). This design enables rapid and seamless tool indexing, reducing non-cutting time and maximizing overall throughput in both single-piece and batch production environments.
Q
What positioning accuracy and repeatability can be expected from these CNC lathes?
Both models achieve a positioning repeatability of ±0.0025mm on all X and Z axes, with spindle runout accuracy of ≤0.003mm and face flatness of ≤0.01mm/Φ100. The twin-spindle coaxiality for synchronization is maintained at ≤0.01mm, ensuring micron-level precision for demanding machining applications.
Q
What measures are taken to ensure thermal stability and long-term machining accuracy?
The machines are equipped with pre-tensioned precision ball screws and high-rigidity linear guideways combined with an automatic lubrication system to minimize friction-induced heat. The hydraulic system integrates an air cooler with premium Taiwanese variable pumps and solenoid valves to maintain optimal oil temperature stability during prolonged machining cycles, effectively reducing thermal displacement.
Q
Is the machine designed with operator safety and workshop cleanliness in mind?
Yes. Both models feature a fully enclosed protective housing with superior waterproof sealing and lightweight sliding doors integrated with safety interlocks. The 65° slant bed design also promotes ergonomic chip disposal, keeping the work area clean. These features fully comply with high-standard modern workshop safety and environmental cleanliness requirements.
