Drilling machine features

Drilling machine refers to a machine tool that mainly uses a drill bit to machine holes in a workpiece. Usually the drill bit rotates for the main motion and the drill bit moves axially for the feed motion. The drilling machine has a simple structure and relatively low machining precision. It can drill through holes and blind holes, replace special tools, expand, boring, reaming or tapping. During the machining process, the workpiece does not move, the tool moves, the tool center is aligned with the center of the hole, and the tool is rotated (main motion). The characteristics of the drilling machine are that the workpiece is fixed and the tool is rotated.
