The working principle and nature of boring machines are similar to those of milling machines. The rotation of the tool is the main motion, and the movement of the workpiece is the feed motion.
Boring machines are mostly used to process longer through holes, large diameter stepped holes, holes in different positions on large box parts, etc. Since the boring machine’s cutter head and boring bar have high rigidity, the straightness, cylindricity and position of the processed holes are very high.
Milling machines can also be used for boring holes, but the processing range is smaller and the accuracy is also lower. Milling machines are mostly used for processing planes, forming surfaces, grooves, etc.
