我厂用滚压法制造的滚丝轮已经多年了。几年来的实践证明:滚压的滚丝轮不会产生因磨制滚丝轮的螺纹表面不平、齿顶园弧“R”转接不园滑以及磨制滚丝轮时发生的螺纹表面的烧伤、退火甚至产生裂纹等难以避免的疵病。同时,由于滚压滚丝轮螺纹的纤维是连续的,淬火后的硬度得到了可靠的保证,这就显著地提高了滚 Roller roller factory in our factory has been rolling for many years. Years of practice has proved that the rolling of the rolling wheel does not produce due to uneven surface of the grinding thread rolling thread, tooth top garden arc “R” adapter is not Park slip and grinding thread rolling surface of the wheel Burn, annealing or even crack and other unavoidable defects. In the meantime, since the threads of the rolled thread rolling thread are continuous, the hardness after quenching is reliably guaranteed, which significantly improves the rolling
