Most of the bolts are made of 15CrNiMo, the hardness is 250~280HB, the thread is M52~M120, and the precision is 6H. Processing such a large pitch thread requires a high degree of durability for the tool. To this end, we have designed a machine-folded external thread turning tool, which has achieved excellent cooperation with Dalian No. 2 Machine Tool Factory.
