本文件参照ISO 230-1规定了在垂直Z轴提供主要切削运动的表面式拉床上进行的几何试验。 它还规定了与上述试验相对应的适用公差，适用于正常精度垂直表面式拉床。 本文件解释了垂直表面式拉床的不同概念或配置以及常见特征。它还提供了相关术语和轴的名称。 本文件仅涉及拉床精度的验证。 它不适用于拉床的操作测试（例如振动、异常噪音、斗杆- 部件的滑动运动），也不影响拉床的特性（例如速度、进给），因为此类检查通常在测试精度之前进行。

This document specifies, with reference to ISO 230？1, the geometric tests on surface type broaching machines with vertical Z-axis providing the main cutting motion. It also specifies the applicable tolerances corresponding to the tests mentioned above for normal-accuracy vertical surface type broaching machines. This document explains different concepts or configurations and common features of vertical surface type broaching machines. It also provides related terminology and designation of axes. This document deals only with the verification of the accuracy of the broaching machine. It does not apply to the operational testing of the broaching machine (e.g. vibration, abnormal noise, stick-slip motion of components), nor to broaching machine characteristics (e.g. speeds, feeds) as such checks are generally carried out before testing the accuracy.
