Scope: This standard specifies the inspection methods and the corresponding tolerances for the geometric accuracy, working accuracy, axis positioning accuracy, repeat positioning accuracy of general-purpose ordinary precision table movable cylindrical grinders, universal cylindrical grinders and end face cylindrical grinders. . This standard is applicable to ordinary-grade precision cylindrical grinders and universal cylindrical grinders with a maximum grinding diameter of 50 mm to 800 mm and a maximum grinding length of 150 mm to 4000 mm, as well as the It is an end face cylindrical grinding machine with ordinary precision and a length of 150 mm to 3 000 mm. This standard is only applicable to the accuracy inspection of machine tools, not to the operation inspection of machine tools (such as vibration, abnormal noise, crawling of moving parts, etc.), or the parameter inspection of machine tools (such as speed, feed rate, etc.). These tests should be performed before precision tests.
