Boring can correct hole eccentricity and achieve high-precision hole position, roundness, cylindricity, and surface finish. It is often used as the final step in high-precision machining.
Its applications cover the machining of disc-shaped parts, small brackets, and box-shaped parts (such as support holes and internal grooves), as well as equipment manufacturing industries such as machine tools and precision machinery. For large-diameter, deep-hole parts, there are specialized lightweight boring tools (such as the CoroBore series), which simplify clamping and improve stability by reducing weight and tool-changing torque, and are suitable for horizontal boring machines and machining centers. Deep-hole boring is a difficult machining process, requiring specially designed boring tools (such as deep-hole boring tools with guide blocks and chip removal holes, or self-centering deep-hole variable-diameter boring tools) to solve problems such as difficult chip removal, high cutting temperatures, and large length-to-diameter ratios.
