本文介绍用激光测量套圈沟道表面光洁度的方法。测量外圈沟道表面光洁度时不需破坏套圈,从仪器的表盘上可直接得出光洁度等级。仪器的技术参数是:被测工件外圆或内孔直径为Φ30～50毫米;测量光洁度范围9～13;测量误差不大于1小级。
This article describes how to measure the surface finish of a ferrule with a laser. Measuring the outer surface of the outer ring groove without destroying the ring, from the instrument’s dial can be directly drawn finish grade. The technical parameters of the instrument are as follows: the diameter of the outer circle or inner hole of the tested workpiece is Φ30 ~ 50mm; the measurement finish range is 9 ~ 13; and the measurement error is not more than 1 level.
