With reference to GB/T l7421.1, this standard stipulates the inspection of geometric accuracy and working accuracy and the corresponding tolerances of horizontal-axis internal grinding machines with or without end grinding wheel frame for general purpose and ordinary precision. This standard is only used for precision inspection of machine tools, not for operation inspection of machine tools (vibration, abnormal noise, crawling of moving parts, etc.), nor for parameter inspection of machine tools (speed, feed rate, etc.). These checks should normally be performed prior to precision testing.
