The provisions contained in the following standards constitute the provisions of this standard through citations in this standard. At the time of publication, the editions indicated were valid. All standards will be revised. Parties using this standard should explore the possibility of using the latest version of the following standards, GB/T17421.1-1998 General Inspection of Machine Tools Part 1: Geometry of machine tools under no load or finishing T. conditions Accuracy 3 General requirements
3.1 Refer to GB/T17421.1-1998 3.1 to adjust the machine tool installation level. When adjusting the installation level, the rotary plate is placed at 90° according to the scale cursor, and other moving parts are placed at the middle position of the stroke. Place a flat ruler on the circular guide rail of the machine tool, and place a level on the flat ruler. The horizontal and vertical readings of the level shall not exceed 0.02/1000. 3.2 During inspection, the actual sequence can generally be arranged according to the requirements of assembly and disassembly of inspection tools and convenience for inspection. 3.3 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/T17421.1-1998. If the conversion result is less than 0.001mm, it shall still be calculated as 0.001mm. State Machinery Industry Bureau approved the implementation on 2000-01-01 on 1999-05-20
