TB2570-8 Gold Medal Cutting Machine Tool Precision Inspection General Rules 3 General Requirements 3.1 Interpretation of the provisions in 3.1 of JB267-82 to adjust the safety level of some machine tools. Place the level on the workbench or the special plate for the bed rails. The level should not exceed (04/1UU) in both the numerical and numerical directions. 3.2 The marking must refer to JB2670, especially the installation before the test, the stability of the main frame and other components, the inspection method and the accuracy of the inspection. 3.3 The standard sequence length is selected according to the structure of the machine tool. 3.4 The inspection sequence can generally be based on the numerical control inspection and the inspection convenience. 3.5 When the measured length is different from the standard, the difference should be converted according to the measurable length according to the provisions of 2.3.1.1 in JB267082. When the conversion result is less than +0.005mm, it is still within 0.005mm.
