线切割机精度按国标规定分为机床几何精度、机床数控精度和工作精度三项,其中机床几何精度须经常检测并随时进行调整。在实践中,我们经常对工作台移动在垂直面内和水平面内的直线度、工作台移动对工作台面的平行度、工作台运动的矢动量以及贮丝筒的跳动等进行检测,而忽略了工作 The accuracy of wire cutting machine according to the national standard is divided into three parts: machine geometry accuracy, machine tool numerical control precision and work precision, in which the geometric accuracy of the machine tool must be constantly checked and adjusted at any time. In practice, we often check the straightness of the table moving in the vertical plane and the horizontal plane, the parallelism of the table movement to the worktable, the momentum of the table motion and the bobbin beating, jobs
