引言迄今磨削被广泛认为用来制造几何形状精确和光洁度高的零件的精加工方法。因此过去磨削工艺似乎主要着眼于达到这些目的。但近年来新发展用于重切削的磨床,其磨削生产率已能达到车削或铣削的生产率。换言之,现代磨削工序可称为机加工——光整工序或叫高效率磨削工序。这篇文章论述了由日本机工试验所(前国立机械试验所)进行高效率磨削研究的试验结果。此处“高效率磨削”一词的含义同时包括高速磨削和强力磨削(即abrasivemachining)。采用这种工艺较传统的磨削工艺生产率来得高并较经济。
Introduction Grinding has hitherto been widely considered as a finishing method for the manufacture of parts of high precision and finish. Therefore, the past grinding process seems to focus mainly on achieving these goals. However, in recent years, newly developed grinders for heavy cutting have been able to achieve the productivity of turning or milling productivity. In other words, a modern grinding process can be called a machining-finishing process or a high-efficiency grinding process. This article discusses the results of a high-efficiency grinding study conducted by the Japan Machine Tool Laboratory (former National Machinery Laboratory). The meaning of the term “high efficiency grinding” here includes both high speed grinding and intensive grinding (ie, abrasive machining). Using this process more traditional grinding process productivity is higher and more economical.
