[0002] With the development of economy and the progress of society, functional toolholders are becoming more and more common in production. In various square hole processing, since it is impossible to process special-shaped holes directly on CNC machine tools, the production efficiency is low, the processes cannot be concentrated and need to be carried out in sequence, which also increases the production cycle. The processing of square holes and other special-shaped holes on existing products is either through milling shape trajectories on CNC, which leads to low efficiency and some shapes cannot be processed. Some special-shaped holes, such as hexagonal holes, need to be processed on special equipment such as wire cutting equipment; this leads to an increase in the number of product processes and a longer processing time. Because the separate processing of special-shaped holes, etc., also leads to multiple clamping of products on different equipment, it will also cause bumps, scratches, etc. during the circulation process; at the same time, the processing error will also become larger, and the product quality will be reduced.
