1. Z-axis Guide Rail Horizontal Installation: With the horizontal installation of the guide rail, the weight and cutting force are evenly distributed among the four sliders, reducing the wear of the slide blocks and prolonging the service life of the guide rail.
2. High Flat Bottom Guide Rail Slant Bed: The high flat bottom guide rail slant bed ensures consistent performance throughout the machining, assembly, and usage processes, ensuring the precision of the machine tool.
3. Premium Castings: The main castings are made of high-quality Meehanite advanced cast iron using resin sand casting process. Through advanced finite element analysis technology, the structure is designed to be reasonable and the layout is optimized. The castings are further treated with secondary aging to ensure long-term machining stability of the machine tool.
4. Precision Ball Screw Transmission: Both the X-axis and Z-axis ball screws adopt precision ball screws, along with scientific pre-tension assembly process, resulting in minimal thermal deformation and high transmission accuracy.
5. Support and Locking System: The support of the ball screws adopts precision bearings from well-known brands, and the locking nut adopts high-precision locking nut, improving the support and locking accuracy of the ball screws, further enhancing the machining precision of the machine tool.
6. Automatic Centralized Lubrication System: The CNC lathe is equipped with an automatic centralized lubrication system that lubricates the moving parts such as ball screws and guide rails through preset lubrication intervals and durations, ensuring the normal operational accuracy and service life of the machine tool.
