This invention relates to the field of vertical milling and turning technology, and discloses a vertical milling and turning composite machining center, including a machining table, a support frame, a vertical cantilever, a drive motor, and a drive shaft. A composite machining mechanism for switching machining types is mounted on the side of the vertical cantilever; a switching mechanism for changing the workpiece's motion state according to the machining type is provided below the composite machining mechanism; a spraying mechanism for changing the coolant's application according to the machining type is provided on the upper surface of the machining table; a clamping mechanism for fixing a ring-shaped workpiece is provided at the top of the switching mechanism; the composite machining mechanism includes a sliding frame plate, with two double-toothed plates slidably connected inside the sliding frame plate. This invention utilizes the forward and reverse directions of the vertical cantilever's lifting stroke to correspond to different machining actions, improving the continuity of actions and machining efficiency, and ensuring the positional stability and synchronization accuracy of the milling cutter and drill bit near the workpiece.

This application provides a method for improving the enzymatic degumming efficiency of flax stems through the synergistic effect of ultrasound and alternating current (AC) electric field, belonging to the field of textile materials technology. The method involves immersing flax stems in a composite enzyme solution, applying an AC electric field and an ultrasonic field, with the AC and ultrasonic fields continuously alternating, and finally inactivating the enzyme to obtain flax fibers. The ultrasonic power density is 0.1 W / mL–2.0 W / mL, and the AC electric field strength is 1 V / cm–5 V / cm. This method achieves this through the synergistic effect of a low-voltage AC electric field and an ultrasonic field. The low-voltage AC electric field activates enzyme activity without inactivating it, while the ultrasonic field removes the gums degraded by the reactivated enzyme solution. Furthermore, the low-power-density ultrasonic field enhances enzyme activity with minimal damage. This synergistic effect improves the efficiency of the flax fiber enzymatic hydrolysis process and maintains the fiber strength of the flax fibers.
