一、学习“群钻”的体会“群钻”问世以来,对我国钻削加工起到了极其巨大的推动作用,我在长期学习和运用“群钻”的生产实践中,对其独到的优越性有深切的体会.和世间任何事物都是不断发展变化的一样,“群钻”也需要发展创新.我在钻削大直径孔的实践中,发现“群钻”还存在着卷屑困难、排屑不畅、散热不良的问题.为解决这一问题,我与北工大陈章燕教授合作,经6年多时间的探讨摸索,在“群钻”的基础上改进创造了五尖九刃麻花钻头,基本解决了上述问题.
First, the study of “group drilling” experience Since the advent of “group drilling” on China’s drilling has played an extremely huge role in promoting my long-term learning and the use of “group drill” in the practice of production, its unique superiority Have deep experience .As with anything in the world are constantly evolving, “group drilling” also need to develop innovation.I drill in the practice of large diameter holes, found that “group drilling” there are still difficult to roll, row In order to solve this problem, I worked with Prof. Chen Zhangyan from Beigong University to explore and explore for more than six years. On the basis of “group drilling”, I improved and created the five-pointed nine-edge twist drill bit, The basic solution to the above problems.
