20 Series 500
CNC lathes are among the most widely used CNC machine tools. They are primarily employed for machining the inner and outer cylindrical surfaces of shafts and disc‑shaped parts, as well as internal and external conical surfaces with arbitrary taper angles, complex rotating internal and external surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, reaming, and boring operations.
High-speed, quiet ball screws enhance machine tool accuracy, ensure machining stability, deliver high positioning precision, and minimize wear to maintain accuracy over extended periods.

Product Details
Product Features
● 45° integral inclined bed design, offering high rigidity and smoother chip evacuation.
● Finite element structural analysis demonstrates a well‑designed rib layout, resulting in excellent stress distribution.
● The X/Y/Z-axis ball screws all feature a pre-tensioned design, which minimizes the impact of thermal expansion during machining on screw accuracy. Oil seals are installed at both ends of the screws to protect the screw bearings, resulting in quiet operation.
● The tailstock features linear hardened‑steel guideways, offering high rigidity under heavy loads and a two‑layer structure. A fine adjustment mechanism is provided between the upper and lower layers, enabling precise micro‑adjustment of the tailstock centerline along the X‑axis. It is standardly equipped with a live center tailstock design.
● Evergrande’s independently designed integrated permanent‑magnet synchronous spindle housing delivers low noise, high precision, long service life, superior surface finish, constant torque output, and exceptional C‑axis positioning accuracy.
● Wide range of optional accessories: such as a material feeder, a workpiece receiver, a large hollow chuck, an enlarged spindle through-hole, a tool setter, and an automated gantry robot.
● The machine tool features a modular design, allowing customers to select equipment with different functions based on their specific product requirements, enabling rapid implementation of automated systems and meeting diverse customer needs.
Roller guide rail
High-precision linear rolling guideways enhance travel speed and significantly reduce non-cutting time. Featuring imported ball‑bearing guideways, they deliver superior positioning accuracy, minimal wear, and long-term precision retention, thereby boosting productivity and ensuring machining stability.
45° Integrated Tilted Bed Design
High-speed, quiet ball screws enhance machine tool accuracy, ensure machining stability, deliver high positioning precision, and minimize wear to maintain accuracy over extended periods.
