Through the compound cam's ‘one-to-three drive’ mechanism, the complex arrangement of 12-speed gear shifting is transformed into a convenient and straightforward cyclic shifting system. The precise transmission ratio renders the gearing relationship more scientifically optimized, further highlighting the advantages of low power consumption and high torque output. The improved multi-stage gear structure effectively reduces gear noise, enhancing the pleasantness of machine tool operation. The spindle support employs medium-series tapered roller bearings for high load-bearing rigidity; the ends feature cam-locking connections to the chuck or face plate. Multiple patented technologies are employed.
