At the same time, the helical gear C232 drives the helical gear E241 to rotate, so that the finish milling spindle 24 drives the finish milling cutter head 25 to work. When the rough milling cutter head 27 is needed, rotate the locking sleeve 14, and then pull the rough milling spindle 26 through the pull ring 262 to make the helical gear F261 and the helical gear D233 mesh to complete the power transmission operation. At the same time, the number of teeth of the helical gear E241 is less than that of the helical gear C232, so it performs a high-speed and low-torque operation. The diameter of the helical gear F261 is larger than that of the helical gear D233, making the rough milling spindle 26 perform a low-speed and high-torque operation.
