一、概述盘丝是三爪自定心卡盘的关键零件。盘丝平面螺纹在卡盘行业以往一直只能在计量室用“万工显”做静态测量。测量点少,效率也低。为了满足盘丝大批量生产质量控制的需要,我扪研制了HTF—CO1型光栅式平面螺纹检查仪,用来专门检测盘丝平面螺纹的螺旋综合误差。仪器的测量基准是高精度的长光栅和 First, an overview of the wire is a three-jaw self-centering chuck key components. Flat-wire thread in the chuck industry in the past has been only in the measurement room with “million workers significant” static measurements. Measuring point less, efficiency is also low. In order to meet the needs of quality control of high-quality coil, we have developed HTF-CO1 grating flatness thread tester, which is used to detect spiral comprehensive error of spiral thread. The instrument’s measurement base is a high-precision long grating and
