近年来,由于国防工业、精密机械以及仪器议表制造业的发展,对精密圆刻线机的刻划精度要求很高,用途要求很广:要既能刻码盘、光栅盘,又能刻度盘;既能光刻,又能刀刻。按照设计要求,QGG405型光电圆刻线机刻出的盘子(包括光刻光栅盘和刀刻度盘),其直径全中误差应小于±0.2秒。因此,QGG405型光电圆刻线机的总精度检验工作,就相当于0.2秒光栅盘和光学度盘直径误差的检验工作。现简单叙述如下。一、检验方法对刻线机刻出的盘子的精度检验,我们用定角法观测,按海佛林克法的公式进行计算。这种方法是以直径全中误差为指标来评定度盘质量的。这和
In recent years, due to the development of national defense industry, precision machinery and instrument manufacturing industry, the precision of engraving precision circular engraving machine is very high, and the requirements are very wide. It is necessary to engrave code plate, grating plate and scale Disc; both lithography, but also knife engraving. According to the design requirements, QGG405 Optical Circular Marking Machine engraved plate (including lithography grating and knife dial), the diameter of the error should be less than ± 0.2 seconds. Therefore, QGG405 optical circular line marking machine of the total accuracy of the inspection work, equivalent to 0.2 seconds grating disk and optical disk diameter error inspection. Now briefly described below. First, the test method The engraving machine engraved out the accuracy of the test plate, we use angle method observation, according to the formula of the Sea Finkingkang calculation. This method is based on the diameter of the error as a whole to assess the quality of dial. with
