Set the coordinate data for drilling through the control panel. Next, the hydraulic rod, the first motor, the second motor, and the third motor are started to operate; Then, according to the size of the gear ring, the left side data of the drilling is set through the control panel, so that the drilling component rotates around the gear ring to drill the hole according to the set value. Different drilling operations can be performed on different gear rings. Finally, the debris generated during the drilling process mixes with the cooling water sprayed from the nozzle and flows into the wastewater tank below the screen holes. It is then discharged and recycled through the waste liquid pipe to prevent the debris from remaining on the base, thus completing the drilling of the gear ring.
