这篇文章是无锡机床厂为设计新产品 ３ ＭＢ １６５０型半自动双列球面滚子轴承外圈滚道磨床所作的试验。通过试验研究找到了新的磨削原理和加工方法，在新产品上应用后取得了良好的效果。这说明经过试验给产品设计提供依据是一项重要工作，产品设计必须以科学试验为基础。 本期发表的另一篇文章是江东机床厂的“Ｘ ６３４ Ｗ型铣床进给系统振动的消除”，最初就是由于没有通过实验而产生了进给系统振动问题，但他们运用基础理论对振源进行分析，抓住主要矛盾采取必要措施，最后得到了改进。 “阶级斗争、生产斗争和科学实验，是建设社会主义强大国家的三项伟大革命运动”。通过科学实验来掌握机床的客观规律，使其贯穿于设计、制造、使用、改造整个过程，将有力地促进我国机床工业多快好省地发展。
This article is Wuxi Machine Tool Plant to design a new product 3 MB 1650 semi-automatic double row spherical roller bearing outer ring raceway grinder made the test. Found through the experimental study of the new grinding principle and processing methods, the new product has achieved good results. This shows that after the test to provide basis for product design is an important task, product design must be based on scientific experiments. Another article published in this issue is “Elimination of Vibration of the Feed System of the X 634 W Milling Machine” by Jiangdong Machine Tool Works. Initially, vibration of the feed system was not generated through experiments. However, Analyzed and seized the main contradictions to take necessary measures and finally got improvements. “Class struggle, struggle for production and scientific experiment are three great revolutionary movements for building a powerful socialist country.” Through scientific experiments to grasp the objective laws of machine tools, so that it runs through the design, manufacture, use, transform the entire process, will effectively promote China’s machine tool industry to develop more quickly and economically.
