标准摘要
[中文适用范围]: ISO 3070的本部分参照ISO 230-1、ISO 230-2和ISO 230-7规定了几何试验、加工试验、主轴试验以及检查通用数控定位精度和重复性的试验,普通精度、卧式主轴镗铣床,具有固定立柱和可移动工作台。 ISO 3070 的这一部分还规定了与这些测试相对应的适用公差。 这种类型的机床可以配备不同类型的主轴头,例如滑动镗轴和铣削主轴、滑动镗轴和端面头、滑枕或铣滑枕等。 ISO 3070 的这一部分涉及具有工作台纵向(Z 轴)和横向(X 轴)运动、主轴头垂直运动(Y 轴)、镗轴或滑枕运动(W 轴)的机器可能还有端面头(U 轴)中的径向端面滑动件的进给运动,并且可能包括旋转台或分度台。 注:在 ISO 3070 的其他部分中,主轴滑枕运动被指定为 Z 轴。 ISO 3070 的这一部分仅涉及机器精度的验证。 它不适用于机器的操作测试(例如振动、异常噪声、部件的粘滑运动),也不适用于机器特性(例如速度、进给),因为此类检查通常在测试精度之前进行。 [外文原描述]: ISO 3070-1-1:2007 specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, machining tests and tests for checking the accuracy and repeatability of positioning by numerical control of general purpose, normal accuracy, horizontal spindle boring and milling machines having a fixed column and movable table. ISO 3070-1:2007 also specifies the applicable tolerances corresponding to these tests. ISO 3070-1:2007 concerns machines having have both longitudinal (Z axis) and transverse (X axis) movement of the table, a vertical movement of the spindle head (Y axis), movement of the boring spindle or ram (W axis) and, possibly, a feed movement of radial facing slide in the facing head (U axis), and that may include a rotary or indexing table. ISO 3070-1:2007 deals only with the verification of the accuracy of the machine. It does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick-slip motion of components) nor to machine characteristics (e.g. speeds, feeds), as such checks are generally carried out before testing the accuracy.
