本文仅对前一阶段的试验研究情况作一简单介绍。 机床的刚度是确定机床基本性能的重要指标之一。机床刚度不足不仅影响加工工件的精度和表面质量,而且还由于不能提高切削速度和进给量而影响生产率。所以目前国内外都很重视提高机床的刚度,并在这方面进行了和正在进行大量的试验研究工作,但多偏于万能机
This article only on the previous stage of the experimental study made a brief introduction. The rigidity of a machine tool is one of the most important indicators for determining the basic performance of a machine tool. Insufficient machine rigidity affects not only the accuracy and surface quality of the machined workpiece but also the productivity due to the inability to increase the cutting speed and feed rate. Therefore, at home and abroad, great attention has been paid to improving the rigidity of the machine tool. In this respect, a great deal of experimental research has been carried out,
