Frequently Asked Questions
Q What is the key advantage of the synchronized twin-spindle design on the NXX-26AS / NXX-36AS?
The synchronized twin-spindle and dual gang tool post system allows dynamic part hand-off between the main and sub-spindles, enabling complete multi-surface machining in a single setup. This significantly reduces geometric tolerances and ensures superior part consistency without additional re-fixturing.
Q What rapid traverse speed do the X and Z axes achieve?
On the NXX-26AS, both the X1/X2 and Z1/Z2 axes achieve a rapid traverse rate of 30 m/min. On the NXX-36AS, the X1/X2 axes reach 24 m/min while the Z1/Z2 axes maintain 30 m/min, supporting high-efficiency production cycles.
Q What positioning repeatability can be expected from these CNC lathes?
Both the NXX-26AS and NXX-36AS achieve a positioning repeatability of ±0.0025 mm on X1/X2 and Z1/Z2 axes, with spindle runout accuracy of ≤0.003 mm, making them suitable for high-precision machining applications.
Q What type of tooling system is used, and how many tools can it hold?
Both models use a T-type gang tooling system (Gang-type Tooling) with a maximum tool capacity of 16 pieces. The unique T-style gang tool post supports versatile multi-tool configurations for rapid and seamless tool indexing.
Q How does the hydraulic and cooling system ensure stable long-term operation?
The machine is equipped with premium Taiwanese variable pumps and solenoid valves, along with an integrated air cooler. This combination guarantees quiet operation and maintains optimal hydraulic oil temperature stability even during extended machining cycles.
Q What are the main differences between the NXX-26AS and NXX-36AS models?
The NXX-36AS offers a larger machining capacity — including a max swing diameter of Φ500 mm (vs. Φ400 mm), a larger bore diameter of Φ45 mm (vs. Φ36 mm), and a greater max bar capacity of Φ35 mm (vs. Φ25 mm). It also features a 45° slant bed angle compared to the 65° on the NXX-26AS, and weighs approximately 4600 kg versus 3500 kg, reflecting its heavier-duty build.
