The provisions contained in the following standards constitute this standard by being quoted in this standard Articles. At the time of publication, the editions indicated were valid. All standards are subject to revision and parties using this standard should explore the possibility of using the latest version of the standard listed below. GB/T17421.1-1998 General Inspection of Machine Tools Part 1: Geometric Accuracy of Machine Tools under No-Load or Finishing Conditions 3 General Requirements
3.1 When using this standard, you must refer to the relevant provisions of GBT.17421.1. Especially the installation before accuracy inspection, the dry running temperature of the spindle and other components, the inspection method and the accuracy of the inspection process. 3.2 Refer to 3.1 in GB/T17421.11998 to adjust the machine tool installation level. The horizontal and vertical readings of the level shall not exceed 0.04/1000.
3.3 The order of geometric accuracy inspection items does not represent the actual inspection order. In order to facilitate the installation and disassembly of inspection tools and inspection, inspection can be carried out in any order.
3.4 ??When the actual measured length is different from the length specified in this standard, the tolerance shall be converted according to the measurable length according to the provisions of 2.3.1.1 in GB/T17421.[--1998. When the conversion result is less than 0.001mm, it is still calculated as 0.001mm. The State Machinery Industry Bureau approved the implementation on 2000-01-01 on 1999-05-20
