A boring machine uses a single point cutting tool mounted on a boring bar to enlarge holes in hollow parts by turning the internal surface. The document describes the components of boring machines like the bed, base, table, and columns. It outlines the main types of horizontal boring machines like table, planer, and floor types, as well as vertical boring machines with single or double columns. Boring machines precision enlarge holes using boring bars with single point cutting tools.
