2020-03-19 14:18 Hits:635
The disadvantages of inner diameter rolling cutter thread are as follows:
1. The compression of base metal leads to work hardening and reduces the fatigue life of thread;
2. The material has limitations, and the hardness of the material for rolling thread shall not exceed hrc40;
3. High requirements for blank dimensional accuracy;
The precision and hardness requirements of rolling die are also high
