标准摘要
[中文适用范围]： 本国际标准参照ISO 230-1规定了两爪以上机床用自定心手动卡盘的几何试验和相应的公差。 这种类型的卡盘具有被称为“一体式硬卡爪”的卡爪，其相对较大的行程可以快速适应各种尺寸的工件，而无需拆卸。 本国际标准仅涉及卡盘旋转精度、工件校直和定心的检验。 它不适用于其他动态量，例如平衡力的测量或夹持力的测量。 [外文原描述]： ISO 3089:2005 specifies, with reference to ISO 230-1, the geometric tests and corresponding tolerances for self-centring, manually-operated chucks for machine tools with more than two jaws. This type of chuck has jaws known as "one-piece hard jaws", the relatively large stroke of which allows quick adaptation to the most varied sizes of workpieces without dismounting. ISO 3089:2005 deals only with the inspections of rotational accuracy of the chuck, the straightening and the centring of workpieces. It is not applicable to other dynamic quantities, such as measurement of counterbalancing or measurements gripping powers.
