Description

technical field

[0001] The invention relates to a processing tool, in particular to a compound hole processing tool which can be spliced ​​and combined. Background technique

[0002] At present, compound tools for hole machining are mainly tools with integral tool bodies. Each tool can only process a limited type of hole. The current compound tools are basically non-standard tools, which are manufactured according to the requirements of the holes to be processed. Corresponding composite cutters, in some single-piece and small-batch production, it is not suitable to use non-standard cutters if composite holes are to be processed, otherwise it will increase the cost of processing, and processing with multiple cutters will reduce production efficiency, and the hole Concentricity of processing is also an issue.

[0003] The damage of a compound tool is often a part of the tool is damaged, but part of the damage leads to the scrapping of the entire knife. When the individual bla...
