开式机械动力压力机验收条件 精度检验

[中文适用范围]： 规定了开放式机械动力压力机的几何测试，并给出了相应的允许公差。 它适用于通用用途和正常精度高达 2 500 kN 能力的机器，并且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）或其特性（速度、进给量等）的测试，一般应在精度之前检查。 经测试。 [外文原描述]： Specifies geometrical tests on open front mechanical power presses and gives the corresponding permissible tolerances. It is applicable to machines of general purpose use and normal accuracy up to 2 500 kN capacity, and 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 its characteristics (speeds, feeds, etc.), which should generally be checked before the accuracy is tested.
