立式转塔和单轴坐标钻床检验条件 精度检验

[中文适用范围]： 规定了这些通用和普通精度钻床的几何和实际测试，并给出了相应的允许偏差。 它仅涉及机器精度的验证。 不适用于机器运行（振动、异常噪声、部件粘滑运动等）或特性（速度、进给量等）的测试，一般应在精度之前检查经测试。 给出了这些机器最常见的配置。 [外文原描述]： Specifies both geomertrical and practical tests on these general purpose and normal accuracy drilling machines, and gives the corresponding permissible deviations which apply. It deals only with the verification of the accuracy of the machine. It does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of components, etc.), or to characteristics (speeds, feeds, etc.), which shall generally be checked before the accuracy is tested. The most common configurations of these machines are given.
