采用微型电子量规和自动定心二坐标测头,利用微计算机进行教据的采集、运算、处理和控制,实现了对直径为0.19mm微小孔径及其与外圆同心度的自动检测、自动分组、测量结果的显示和打印,比手工检验提高效率几十倍,为微小孔径及其与外圆同心度的自动测量提供一条新途径。 The use of micro-electronic gauge and automatic centering two coordinate measuring head, the use of micro-computer teaching data collection, computing, processing and control, to achieve a diameter of 0.19mm tiny aperture and its concentricity with the automatic detection, automatic grouping , The measurement result display and the printing, enhances the efficiency several times than the manual inspection, provides a new way for the small aperture and its automatic measurement with the concentricity of the outer circle.
