标准范围

本文件参考ISO 230-1和ISO 230-2规定了几何试验、加工试验以及通用和普通精度手动和数控（NC）外圆无心磨床定位轴的精度和重复性试验。它还规定了与上述试验相对应的适用公差。本文件仅涉及机器精度的验证。它不适用于机器运行的测试（振动、异常噪音、部件的粘滑运动等），也不适用于机器特性（如速度、进给等），通常在测试机器精度之前进行检查。本文件提供了机器主要部件使用的术语，以及参考ISO 841的轴的名称。注:除了ISO官方语言（英语和法语）中使用的术语外，本文件还提供了德语、意大利语、日语和波斯语中的等效术语。这些文件由德国（DIN）、意大利（UNI）、日本（JIS）和伊朗（ISIRI）的国家成员机构负责发布。然而，只有官方语言中给出的术语才可视为ISO术语。

The document specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, machining tests and tests for accuracy and repeatability of positioning axes on general purpose and normal accuracy manually and numerically controlled (NC) external cylindrical centreless grinding machines. It also specifies the applicable tolerances corresponding to the above-mentioned tests.This document deals only with the verification of accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noise, stick-slip motion of components, etc.) nor to machine characteristics (such as speeds, feeds, etc.), which are generally checked before testing of machine accuracy.This document provides the terminology used for the principal components of the machine and the designation of the axes with reference to ISO 841.NOTE In addition to the terms used in the official ISO languages (English and French), this document gives the equivalent terms in the German, Italian, Japanese, and Persian languages. These are published under the responsibility of the national member bodies for Germany (DIN), Italy (UNI), Japan (JIS), and Iran (ISIRI). However, only the terms given in the official languages can be considered as ISO terms.
