[0002] A drilling machine refers to a machine tool that mainly uses a drill to process holes on a workpiece. Usually, the main motion is rotation of the drill bit, 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 processes. During the processing, the workpiece does not move, and the tool moves. The center of the tool is aligned with the center of the hole, and the tool rotates. The characteristic of a drilling machine is that the workpiece is fixed, the tool rotates, and the drill sleeve is installed on a drilling template or a clamp. Its function is to determine the position of the hole to be processed on the workpiece, guide the tool for processing, and improve the rigidity of the tool during processing and prevent vibration during processing.
