摘要
玻锥是彩色显像管的重要结构件，在玻锥生产过程中，面比较流行的两种测量定位方法——定位块定位和参考线定位，管颈倾斜和偏心是必测项目，文章介绍了在玻锥测量方以及特种CMT锥的测量方法。
The glass cone is an important structural element of color picture tubes. In the glass cone manufacturing process, pipe neck tilt and eccentricity is a necessary measuring procedure, this paper introduces two popular methods of measurement positioning in glass cone measurements - positioning block and reference line positioning. And also, this paper introduces special CMT cone measurement method.
