Scope

Main technical content: 4. General requirements 4.1 This standard supplements and refines GB/T 9061–2006, GB/T 25373–2010, GB/T 25376–2010, and JB/T 8801–2017. When inspecting machine tools according to this standard, the remaining relevant inspection items not specified in this document should also be tested simultaneously. 4.2 The order of inspection items in this standard does not indicate the actual inspection sequence. Inspections can be conducted according to the machine tool assembly process. 4.3 All linear dimensions, deviations, and corresponding tolerances in this standard are expressed in millimeters (mm); angle dimensions are expressed in degrees (°), and angle deviations and corresponding tolerances are represented as ratios. When necessary, they can be expressed in micro-radians (μrad) or arcseconds (″). The equivalent relationship of the expressions is shown in Equation (1): 0.010/1000 = 10×10-6 = 10μrad ≈ 2(1) 4.4 The inspection tools specified in this standard are for illustrative purposes only. Other inspection tools with the same indicative quantity and at least the same accuracy can be used. The indicator should have a resolution of 0.001mm. When the actual measured length differs from the length specified in this standard, the tolerance shall be converted according to the provisions of GB/T 17421.1–1998, Section 2.3.1.1, based on the measurable length. If the conversion result is less than 0.005mm, it shall still be calculated as 0.005mm.
