MC007 系列大型工具显微镜 MC007 系列（JGX-2）一、 JGX-2 大型工具显微镜产品简介： JGX-2 大型工具显微镜是一种最基础的精密光学测量仪器。

大型工具显微镜为机器制造工厂、科学研究机关及高等院校的计量部门广泛使用的一种多性能计量仪器。可作以下各项测定：

检定样板、样板刀、样板铣刀、冲模和凸轮的形状
测量螺纹的中径、外径、内径、螺距、螺形角、螺形角对螺纹轴的轮廓位置和螺纹形状（齿形圆整性、平面性、平直角等）
测量螺纹车刀、螺纹梳形车刀、螺纹铣刀的螺形角，各种样板铣刀和各种形状的样板轮廓角等
使用光学定位器测量内孔和各种槽的宽度
使用双像目镜测量两孔间中心距离及零件上的狭缝、线段或具有对称图形的图形之间的距离等
使用圆弧轮廓目镜，可方便精确地测量 R0.1~R100 的圆弧尺寸
