标准摘要
[中文适用范围]： ISO 3442的本部分规定了90°和60°锯齿以及适用于90°和60°锯齿的卡爪螺母，用于将顶爪安装在动力卡盘的基爪上，以确保互换性。 它还参考 ISO 230-1 描述了带有两个或多个两片式卡爪（锯齿型）的自定心电动卡盘的几何测试，以及适用的相应公差。 [外文原描述]： ISO 3442-3:2007 specifies 90° and 60° serrations and jaw nuts applicable to 90° and 60° serrations for mounting the top jaws on the base jaws of power chucks, in order to ensure interchangeability. It also describes, with reference to ISO 230-1, the geometric tests for self-centring, power-operated chucks with two or more two-piece jaws (serrated type), and the corresponding tolerances which apply.
