我厂在安装大型龙门刨床时,拟用钢丝法检验导轨在水平面内的直线性,但没有专用的显微镜,而长20公尺的导轨是由三节并成的,导轨在水平面内的直线性很重要,非检验不可;经工人和技术员共同研究,用千分尺和电触信号来代替显微镜,经使用后,效果良好。 这种方法的原理和我厂所用的全 When installing a large gantry planer, our factory intends to test the linearity of the guide rail in the horizontal plane by using the steel wire method, but there is no special microscope. The 20-meter-long guide rail is made up of three sections. The linearity of the guide rail in the horizontal plane is very Important, non-testable; by workers and technicians to study together, with a micrometer and electrical touch signal to replace the microscope, after use, the effect is good. The principle of this method and my plant used in the whole
