Description

Technical Field

[0001] The utility model relates to the technical field of boring cutters, in particular to a precision boring cutter for machining cylinder holes. Background Art

[0002] Shell parts have many hole systems. Such parts are usually bored with boring tools on horizontal machining centers or modular machine tools. However, horizontal machining centers are general-purpose machine tools with low processing efficiency and relatively high investment costs. In order to improve the processing efficiency of shell parts and achieve higher product processing quality at the same time, it is necessary to equip them with high-precision boring tools that are suitable for them. Only by innovating economical and practical equipment and tools can we achieve high processing efficiency and high processing accuracy, so that the quality of processed products fully meets the product design requirements and avoids market risks. Therefore, an economical and practical composite fine boring tool for machining holes of shell parts on CNC modular machine tools is designed. The composite fine boring tool has a compact structure, reliable performance, strong general performance, can meet the requirements of high-precision and high-efficiency processing, and has significant comprehensive economic benefits.
