The following provisions, including those contained in the references in this standard, shall become part of this standard. The terms of the standard. This standard is published, and all copies are valid: All standards will be subscribed by you, so that all parties using this standard can explore the value of use, and the possibility of verifying the latest version is confirmed. 17421.1-199 Machine Tool Inspection Rules Part 1: What is the accuracy of the machine tool under no-load or precision working conditions? 3 Brief description
3.1 The nominal center size of the table is the saddle width of the corresponding slide. 3.2 When using this standard, refer to the relevant meanings of GB/T17421.1. 3.3 The special inspection items listed in this standard are not exhaustive. In order to reduce the loading and unloading and the inspection of the inspection, the inspection can be carried out in any order:
3.4 ​​The inspection tools and instruments specified in this standard are mandatory. In production, on the premise of ensuring the inspection accuracy, other inspection tools and instruments can be used.
4.1 In the inspection items using the ruler, both ends of the ruler should be supported in the best supporting position, with the length of the ruler corresponding to the length of the ruler, so as to minimize the self-winding
4.2 Place the slide on the inspection plate and use 0.03 Cut and check the gap between the sliding seat and the plate with a feeler gauge. The feeler gauge should be used to measure the depth of the slide. After the test, the center 16 precision width test is carried out. 4.3 Only when the dead stop iron of the platform is positioned by a work box, the G? item accuracy is considered to be tested, otherwise it is not tested. The GT test is carried out on the test bench.
