China Suppliers Factory NXX-46BL Slant Bed CNC Lathe with Rotary Turret for Precision Machining Solutions
Key Structural Features
Spindle & 30° Slant Bed Design
Features a monolithic cartridge-type spindle with a '3-front, 2-rear' imported precision-grade bearing layout driven by a servo motor. Cast from resin-sand iron, the 30° slant bed with dense internal ribbing provides maximum rigidity, vibration dampening, ergonomic accessibility, and efficient chip removal.
Motion Axes & Auto Lubrication
Equipped with high-rigidity linear guideways and pre-tensioned ball screws directly coupled to servo motors. An intelligent automated forced lubrication system reduces thermal deformation, maintains positioning accuracy, and drives rapid traverse speeds up to 30 m/min.
High-Efficiency Hydraulic Station
Incorporates premium Taiwanese variable displacement pumps, hydraulic motors, and solenoid valves. Paired with a forced air-cooling unit, it ensures low running noise and stable oil temperature for reliable continuous industrial operations.
Rapid Indexing Rotary Turret
Configurable with hydraulic or servo rotary turrets featuring bi-directional shortest-path tool selection. Achieves ultra-fast indexing times of 0.3–0.5 seconds, unhindered by workpiece dimensions, tailored for heavy-duty disk turning.
Enclosure & Operator Safety
Built with a fully enclosed modern splash guard system delivering reliable sealing. Smooth sliding doors are fully integrated with safety interlock switches, ensuring comprehensive operator and environmental protection.

Frequently Asked Questions
The NXX-46BL offers larger capacities, including a maximum swing over bed of Φ500 mm (vs. Φ480 mm on the NXX-46B), a maximum machining length of 360 mm (vs. 320 mm), and an upgraded X/Z axis servo motor power of 1.8 kW (vs. 1.3 kW).
The machine utilizes a monolithic cartridge-type spindle configured with a '3-front, 2-rear' arrangement of imported precision-grade bearings, achieving radial and axial run-out accuracy of ≤0.003 mm.
The 12-station servo rotary turret features bi-directional shortest-path tool selection with an ultra-fast indexing time of only 0.3 to 0.5 seconds.
The linear guideways and pre-tensioned ball screws support rapid traverse speeds of up to 24 m/min along the X-axis and up to 30 m/min along the Z-axis, with repeatability accuracy within ±0.0025 mm.
Cast using high-grade resin sand iron with dense internal ribbing, the 30° slant bed significantly enhances structural rigidity and vibration absorption while optimizing ergonomic access and gravity-assisted chip removal.
The machine features a fully enclosed splash guard with smooth sliding doors equipped with safety interlocking mechanisms to ensure comprehensive operator protection during machining.
