This lathe ( milling, boring, grinding, drilling, gear cutting, planer) machine is of home manufacture. 这台车床(铣床、镗床、磨床、钻床、切齿机、刨床)是我们国内制造的。
The optimal design of a six-bar linkage to be used in the main driving mechanism of a gear planer is discussed and treated as a multi-objective problem. 本文首先讨论了在插齿机主传动机构中使用的六杆机构的优化设计问题,并建立了一个多目标数学模型。
