High-efficiency CNC vertical lathe, suitable for processing small and medium-sized discs and cover parts. High-strength cast iron base and column provide good stability and shock resistance. Vertical structure ensures convenient clamping of workpieces, small footprint, and oil-water separation structure. The cooling water is clean and environmentally friendly, with a separated cooling water tank that is easy to clean. The precise, high-rigidity cartridge-type spindle structure is easy to maintain. The spindle sleeve is fully symmetrical and suspended, which better eliminates the impact of thermal deformation on machining accuracy. A high-power AC spindle motor enhances the stability of the machine tool operation. The main shaft is lubricated with imported high-grade grease, fully enclosed, and maintenance-free. High rigidity tool holder ensures fast tool change and reliable centralized operation. The X/Z axis adopts high-precision ball screws and special bearings to preserve accuracy. Features integral fully enclosed protection for environmental protection.
