本文件参照ISO 230-1和ISO 230-2规定了一般用途、常规精度的电火花成形机床的几何精度检验、数控轴定位精度和重复定位精度检验及加工精度检验。本文件还规定了与上述检验相对应的公差值。
本文件适用于移动主轴头型的双立柱机床。
本文件仅涉及机床精度的验证,而不适用于机床运行试验(振动、异常噪声、零部件的爬行等)或其参数(如速度、进给量等)的检查,这些检查通常宜在检验精度之前进行。
本文件还规定了用于机床主要部件的术语,坐标轴命名方式参见GB/T 19660—2005。
注:除了用ISO官方语言(英文、法文)表示的术语外,附录A给出了荷兰文、德文、意大利文、瑞典文、波斯文和日文等效术语。这些文种标准的出版由荷兰(NEN)、德国(DIN)、意大利(UNI)、瑞典(SIS)、伊朗(ISIRI)和日本(JISC)国家成员团体负责。但只有用官方语言给出的术语才能视为ISO术语。

This part of GB/T 23480 specifies, with reference to GB/T 17421.1—1998 and GB/T 17421.2—2000, geometric tests, tests of accuracy and repeatability of numerically controlled positioning axes and machining test for general purpose and normal-accuracy small hole high speed drilling electro-discharge machines. It also specifies the applicable tolerances, corresponding to the above-mentioned tests.
This part of standard is applicable to small hole high speed drilling electro-discharge machines, hereinafter referred to as machine.
This part of standard deals only with the verification of accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) or the checking of its characteristics (such as speeds, feeds, etc.), which should generally be checked before the testing of the accuracy.
This part of standard provides the terminology used for the principal components of the machine and t
