经济型数控机床的主要特点是经济和实用,因而需要有一种结构简单,价格便宜,还能保证必要的精度和稳定性的新型伺服元件。为此,我们用电磁离合器进行了尝试(参阅本期封二产品)。 电磁离合器除具备上述要求的特点外,还具有体积小、重量轻、控制线路简单、便于维护、便于机床的改 The main features of economic CNC machine tools are economical and practical, so there is a need for a new type of servo element that is simple in structure and inexpensive in terms of cost while maintaining the necessary accuracy and stability. To this end, we have tried with the electromagnetic clutch (see the current closure of two products). In addition to electromagnetic clutch with the characteristics of the above requirements, but also has a small size, light weight, control circuit is simple, easy to maintain, easy to machine changes
