近来各地采用微机控制装置改造车床取得了不少成绩,但也有些单位感到实际效果并不十分理想,这主要是用户对数控车床性能和特点缺乏正确的认识,使用不当所致。现就经济型数控车床使用中普遍存在的问题和注意事项介绍如下。一、间隙补偿普通车床数控装置大都设计有间隙补偿功能,用来消除传动链的间隙(主要是齿轮传动间隙和丝杆与刀架螺母副的轴向间隙)。要注意的是,这种间隙补偿是假定传动链的间隙量以一个固定常量为前提条件的,故应正确地称它为固定间隙补偿。如果 Recently, various computer control devices have been used to transform the lathe and many achievements have been made. However, some units feel that the actual effect is not very satisfactory. This is mainly due to the lack of proper understanding and improper use of CNC lathes by users. Now on the economy of CNC lathes commonly used in the problems and precautions described below. First, the gap compensation Ordinary lathe NC devices are designed to have clearance compensation function, used to eliminate the transmission chain of the gap (mainly gear transmission gap and the screw nut and the Deputy Vice-axial clearance). It should be noted that this gap compensation is assumed that the amount of transmission chain gap to a fixed constant as a precondition, it should be properly called fixed-gap compensation. in case
