A machine tool that processes holes in a workpiece with a drill bit. Generally, the drill rotation is the main motion, and the drill axial movement is the feed motion. The drilling machine has simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. When the workpiece does not move during processing, let the tool move, align the tool center with the hole center, and make the tool rotate (main
