Taiwan spindle adopts high-quality bearings with good rigidity. BT40 tool handle is standard and BT50 tool handle is optional.HT300 cast iron is adopted for the main foundation parts such as base, sliding seat, workbench, column and headstock; The substructure is a box structure, and the compact and reasonable symmetrical reinforcement structure ensures the high rigidity, bending resistance and damping performance of the foundation parts; A-span column and internal grid reinforcement effectively ensure the rigidity and accuracy of z-axis strong cutting; The basic parts are molded with resin sand and aging treatment, which provides a guarantee for the stability of the long-term service performance of the machine tool.
