Cam finish-milling device for camshaft

The utility model relates to the technical field of cam shaft machining, and provides a cam finish-milling device for a cam shaft, which aims to overcome the defects that cooling liquid is wasted as cooling liquid and machining scraps cannot be collected in time in the prior art, and normal operation of equipment is affected as the machining scraps are accumulated in the equipment. Two sliding rails are fixedly mounted at the top of the workbench, a mounting seat is slidably mounted at the tops of the two sliding rails, the mounting seat is of a U-shaped structure, a collecting box is arranged in the U-shaped structure of the mounting seat, two slopes are arranged at an inlet in the top of the collecting box, and a fastening bolt is arranged on one side of the mounting seat. According to the milling cutter cooling device, the collecting box is arranged, cutting waste generated in the machining process can be collected, meanwhile, cooling liquid used for cooling a milling cutter is collected and filtered, the
