Machining of square hole

The hole for the cutter bar such as the boring bar and the arbor bar is mostly a square hole. These square holes have high dimensional and shape accuracy, as well as high positional accuracy requirements such as symmetry and verticality of the tool bar busbar. Therefore, processing and measurement are relatively difficult. Our factory has researched a simple and easy process plan for the processing of such square holes.
