本文介紹了装配式滚刀在日本的試驗研究情况。近年来,由于工业发展的需要,日本的一些厂校吸取了西德使用装配式滚刀的經驗,开始制造了这种滚刀,并对这种滾刀的結构作了改进。本文作者在这方面进行了不少工作,他們把正前角采用在这种滾刀上,使这种滾刀的性能有了更大的改善。关于在装配式滾刀上采用正前角的一些分析,本文作了介紹,証明了它具有足够的精度。文中还对装配式滚刀的技术經济特性作了叙述。对采用錐形砂輪磨削側螺旋面(以代替铲磨)的精度也进行了分析,証实了此种工艺方法是可行的。最后所介紹的切削試驗結果,綜合地說明了这种滚刀的切削性能及精度,完全符合理論分析,肯定了这是一种具有很大优越性的高效率滚刀。
This paper introduces the experimental research on the hob in Japan. In recent years, due to the needs of industrial development, some Japanese factories have learned the experience of using German-made hobs in the West Germany and started to manufacture such hobs and improved the structure of such hobs. The authors of this work have done a lot of work in this area, and they use the front rake angle on this kind of hob, so that the performance of this kind of hob has been greatly improved. Some analyzes of the positive rake angle on a hob are presented in this article to prove that they have sufficient accuracy. The article also describes the technical and economic characteristics of the assembly hob. The accuracy of grinding the helical side (instead of shoveling) with a tapered grinding wheel was also analyzed, confirming the feasibility of this process. Finally, the cutting test results introduced, a comprehensive description of the hob cutting performance and accuracy, in full compliance with theoretical analysis, affirmed that this is a great advantage of high efficiency hob.
