Machining device for lifting lug set

The machining device for the lifting lug set comprises a main shaft driving unit, a lead screw system, a lead screw driving unit, a bearing seat, a main shaft, a cutter head seat and a cutter. The machining device is simple in structure. In the working process, firstly, a machined workpiece is adjusted, an adjusting bearing seat is installed on a co-machined workpiece, then a main shaft, a cutterhead seat and a cutter are installed in a penetrating mode, a main shaft driving unit, a lead screw system and a lead screw driving unit are installed, after equipment installation is completed, a power source is turned on, and under driving of the main shaft driving unit and the lead screw driving unit, machining is completed. The main shaft drives the cutterhead base and the cutter to do circular motion and axial motion, so that machining of lifting lug group holes and end faces is achieved, machining equipment is easy and convenient to install, the working principle is simple, and the requirement for professional s
