一、概况圆锥量规是机械工业应用极广的量具。这一量具多由各单位自行制定,从而因加工条件、加工精度、检测和使用方法不同等,出现各企业的锥度基准不统一,不能互换的现象,影响产品质量的提高以及机械产品的出口。目前国内大部分单位都采用万能工具显微镜,卧式测长机及正弦规等设备和原理测量, First, the overview Cone gauge is a very wide range of mechanical industry measuring tools. Due to the different processing conditions, processing precision, different testing and using methods, the taper datums of enterprises are not uniform and can not be interchanged with each other, which affects the improvement of product quality and the export of mechanical products . At present, most of the units in China adopt universal tool microscopes, horizontal length measuring machines and sine gauges and other equipment and principles to measure,
