NXX-26AS CNC Lathe: China Suppliers & Factory with Twin-Spindle, Slant Bed Design for Precision Machining
Key Structural Features
Rigid Spindle & Slant Bed
The unit adopts a professional-grade sleeve spindle with a monolithic design, supported by a high-precision 3-front/2-rear bearing configuration. Coupled with a rear-drive servo system, it maintains exceptional stiffness and operational stability during heavy loads.
The 65° slant bed, engineered from high-grade resin-sand casting with an intensive ribbed-plate architecture, combines superior anti-vibration properties with an ergonomic workflow for seamless chip disposal.
Precision Feed System & Tooling
High-Speed Feed Mechanism: Each axis features a direct-drive configuration with servo motors and pre-tensioned precision ball screws. Integrated with high-rigidity linear guideways and an automatic lubrication system, it achieves a 30 m/min rapid traverse and micron-level positioning accuracy while effectively minimizing thermal displacement.
T-Type Gang Tooling: The unique T-style gang tool post supports versatile multi-tool configurations, ensuring rapid and seamless tool indexing for maximized throughput.
Synchronized Twin-Spindle & Dual-Gang-Tooling
The synchronized operation of twin spindles and dual gang tool posts enables dynamic part hand-off (re-gripping) between the main and sub-spindles. This allows for complete multi-surface machining in a single setup, significantly reducing geometric tolerances and ensuring superior part consistency.
Hydraulic & Cooling Performance
Equipped with premium Taiwanese variable pumps and solenoid valves, the system features an integrated air cooler to guarantee quiet operation and optimal oil temperature stability during prolonged cycles.
Enclosure & Safety Compliance
The machine features a fully enclosed protective housing with a sleek, minimalist aesthetic and superior waterproof sealing. The lightweight sliding doors are integrated with safety interlocks, ensuring full compliance with high-standard modern workshop requirements for operator safety and environmental cleanliness.

Frequently Asked Questions
What are the primary operational benefits of the synchronized twin-spindle setup?
The synchronized twin spindles and dual gang tool posts enable dynamic part hand-off (re-gripping) between the main and sub-spindles. This facilitates continuous, complete multi-surface machining in a single setup, substantially cutting cycle times, minimizing geometric tolerances, and ensuring outstanding part consistency.
What spindle runout and axial repeatability does this equipment deliver?
Both the main and sub-spindles maintain a runout accuracy of ≤0.003 mm and a spindle repeatability of 0.01 mm. Additionally, the X1/X2 and Z1/Z2 axes achieve an axis repeatability of ±0.0025 mm, providing micron-level precision during continuous production.
What rapid traverse rates and feed mechanisms are featured?
The axes utilize a direct-drive design with servo motors, pre-tensioned precision ball screws, and high-rigidity linear guideways. On the NXX-26AS, both X and Z axes achieve 30 m/min rapid traverse rates (24 m/min on X axes for NXX-36AS), backed by an automated lubrication system that mitigates thermal displacement.
What is the tooling capacity and specification supported by the gang tool post?
The machine incorporates a T-style gang tooling system with a maximum capacity of 16 tools. It accommodates 20×20 mm outer diameter (O.D.) tools and Φ25 mm boring bars, delivering fast, smooth tool indexing for high throughput.
How does the bed structure aid vibration damping and chip flow?
The machine utilizes a heavy-duty slant bed (65° on NXX-26AS and 45° on NXX-36AS) cast from high-grade resin sand with an intensive ribbed-plate architecture. This delivers superior vibration absorption under heavy cutting while guiding chips smoothly away from working components.
What hydraulic and thermal management features are integrated?
The hydraulic system is outfitted with Taiwanese variable pumps, solenoid valves, and an integrated forced air cooler. This configuration ensures consistent oil temperature control and silent operation over extended production runs.
