Column Drilling Machine – 3D Model SolidWorks

drilling machine refers to a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes, or perform tapping and other processing. During the processing, the workpiece does not move, the tool moves, aligns the center of the tool with the center of the hole, and rotates the tool (main motion). The characteristics of a drilling machine are that the workpiece is fixed, the tool rotates, and feeds along the spindle direction. The operation can be manual or motorized.
