3.1 When using this standard, refer to J8/T41713.2 for the results of machine tool inspection. According to JB4177-1999, adjust the installation level of the machine tool. The horizontal and lateral readings of the water meter placed on the workbench shall not exceed 0.1010003. The order of the precision inspection items listed in this standard does not represent the actual inspection order. For the purpose of assembly and disassembly inspection tools and inspection sequence: inspection can be carried out in any order.
3.4 ​​When the actual measured length is different from the length specified in the standard, it shall be converted according to the provisions of 2.2.1.1 of JB4171-1999 according to the length that can be measured. The product minimum conversion value is 0.01 plus. The static approximation of the number in the disassembly calculation shall comply with the provisions of H/[8170. The accuracy inspection is shown in Table 1. The inspection method of the super-directional jump of the world wheel with a height of 1250 mm is approved by the State Bureau of Machinery Industry on May 1, 1999. The inspection method of the actual shear work is shown in Table 2.
