During the machining process, the workpiece does not move, let the tool move, align the tool center with the hole center, and make the tool rotate (main motion). The boring machine bed is mainly used as a working table for the boring machine. The material is high-strength cast iron. The boring machine is a machine tool that uses a boring tool to bore holes on the workpiece. Usually, the rotation of the boring tool is the main motion, and the movement of the boring tool or the workpiece is the feed motion . The machining accuracy and surface quality of boring machines are higher than those of drilling machines. The boring machine bed is the main equipment for processing large box parts.
