China NXX-46A1 Slant Bed CNC Lathe: High Precision Gang Tool from Reliable Suppliers and Factory
High-Performance Cartridge Spindle
Designed for demanding applications, this machine integrates a high-performance cartridge spindle. Built with premium imported bearings in a "three-front, two-rear" arrangement and powered directly by a servo motor, it delivers exceptional precision, rigidity, and rotational stability.
45-Degree Slant Bed Foundation
Its foundation is a robust 45-degree slant bed made of high-grade cast iron via resin sand molding. The densely ribbed structure provides superior stiffness and effective vibration absorption, while also facilitating easy operation and efficient chip flow.
High-Speed Precision Axes
For rapid and accurate axis movement, the X and Z axes employ high-rigidity linear guides and precision ball screws. These are directly driven by servo motors through flexible couplings, with a central lubrication system servicing all guideways and screws. This design achieves high positioning accuracy, minimizes thermal effects, and enables fast traverse speeds of up to 30 m/min.
Versatile Gang Tool Post
A versatile T-type gang tool post allows for multiple tool arrangements and enables very quick tool changes.
Hydraulic Power Unit
The hydraulic power unit incorporates a variable displacement pump, motor, and solenoid valves sourced from Taiwan. Its integrated air-cooling system maintains low operating noise and stable, cool oil temperatures.
Fully Enclosed Enclosure & Safety
Completing the package is a streamlined, fully enclosed guard with excellent sealing. The smooth-sliding door ensures easy access and is fitted with a safety interlock for operator protection.

The machine features a robust 45-degree slant bed made of high-grade cast iron cast via resin sand molding. Its densely ribbed design provides exceptional stiffness, reduces vibration, and facilitates efficient chip removal.
The cartridge spindle incorporates imported precision bearings configured in a "three-front, two-rear" layout, driven directly by a servo motor. It maintains radial and axial runout of ≤0.003 mm with stepless speeds up to 4000 r/min.
The X-axis delivers a rapid traverse speed of 24 m/min, while the Z-axis reaches up to 30 m/min, driven by high-rigidity linear guides and precision ball screws directly coupled to servo motors.
The machine uses a versatile T-type gang tool post capable of accommodating up to 8 tools (20×20 mm OD tools and up to Φ25 mm boring bars), enabling rapid tool change times and flexible setups.
Both X and Z axes provide a high repeatability precision of ±0.0025 mm, with machining flatness accuracy controlled within ≤0.01/Φ100 mm.
The models vary primarily in swing diameter (Φ360 mm to Φ420 mm), bar capacity (Φ35 mm to Φ45 mm), spindle motor power (4 kW vs 5.5 kW), and axis travel capabilities to suit different component dimensions.
