BB SDJ Boring Cutter Reduce machining process, improve efficiency, reduce boring time. Abandoning the structure that the hole shaft gap of the fine-tuning structure after the locking of the traditional fine-boring tool can not be eliminated, the unique chute coupling principle is adopted, all accessories are tightly fitted, and the locking screw is not in contact with the fine-tuning mechanism, so as to achieve large margin cutting and precise fine-tuning, so that the boring efficiency is increased by more than twice, and the blade loss is reduced by more than 5 times, and the stability is…
