Taking into account the increase in my country, when adopting 5113:197, this part assumes some links: the relevant technical differences have been artificially upgraded and the margins of the items they involve are marked with a dot in the text. A list of the reasons for these technical differences is given in the appendix for reference.
For easier use: 1) For Part 17013:1997, the following normative changes are made: 1) "This standard" is changed to "This part"; 2) "Brief description" is changed to "General requirements"; 3) "General requirements" is changed to "General requirements" in the title of the chapter: 4) "General requirements" is changed to "General requirements" in the title of the chapter: 5) "General requirements" is changed to "General requirements" in the title of the chapter: 6) "General requirements" is changed to "General requirements" in the title of the chapter: 7) "General requirements" is changed to "General requirements" in the title of the chapter: 8) "General requirements" is changed to "General requirements" in the title of the chapter: 9) "General requirements" is changed to "General requirements" in the title of the chapter: 10) "General requirements" is changed to "General requirements" in the title of the chapter: 11) "General requirements" is changed to "General requirements" in the title of the chapter: 12) "General requirements" is changed to "General requirements" in the title of the chapter: 13) "General requirements" is changed to "General requirements" in the title of the chapter: 14) "General requirements" is changed to "General requirements" in the title of the chapter: 15) "General requirements" is changed to "General requirements" in the title of the chapter: 16) "General requirements" is changed to "General requirements" in the title of the chapter: 17013:1997 In order to link the two parts of the standard, the conceptual part is only applicable to the lower type machine tool: adding a top drive, that is, G3:1 workbench longitudinal movement of the horn compensation difference, this part of the annex A is a reference annex.
This part is issued by China Machinery Industry Federation. This part is under the umbrella of China Machinery Tool Standardization Technical Committee (CS1S/122) and the second part of the initiator of Beijing First Machine Factory and Long March Machine Tool Co., Ltd.

GB/T 3333.3:2002
This part specifies the requirements and test methods for the vertical milling machine precision test and the test conditions for the vertical milling machine precision test. This part is applicable to ordinary folding milling machine precision test machines with a working table width of 20Umm~.50mm. 2 Normative references
The following documents have become the references to this part through the reference of this part. For all references with a date of reference, all subsequent revisions (excluding errata) shall not use this part. However, it is encouraged to report this part. The parties to the agreement shall study whether the latest versions of these documents can be used. For all referenced documents not included in the plan, the latest versions shall be used for the following ten parts:

4. 1 Units of measurement
In this part, all linear dimensions are expressed in metres. For the sake of clarity, the differences are expressed as ratios. In some cases, micrometres are used as units. The conversion relationship is as follows: (1/0001u10-10arad2
2.? In accordance with standard
, this part shall be used in accordance with G3/17421, 1-199H, and the recommended accuracy of the equipment, measurement methods and inspection methods shall be maintained. 4.3 Inspection sequence
The inspection items specified in this part are not listed in the actual inspection sequence. In order to ensure the inspection of installed tools It is convenient to start the inspection at any time.
4.4 Inspection items
When inspecting machine tools, the root structure waiting points are not sufficient for all the inspection items in the required inspection part. In order to meet the requirements before acceptance, the inspection items specified in the manufacturer's specifications can be obtained before acceptance. However, these inspection items must be specified when ordering machine tools. 4.5 Inspection tools
Take the inspection tools specified in this part as an example. The same indicating amount or tools with at least the same precision can be used. The two indicators of the tools should have a substation of 0.1m or higher: 4.6 Working seat inspection
This part only uses screening for work accuracy inspection. GH/T 3933.3—2D02
4.7 Small tolerance position
When the actual length is different from the length specified in this part, the difference shall be calculated according to the provisions of 2.3.1.1 of 8/117121.11998. When the conversion result is less than 0.5rm, it shall still be inspected in the following directions according to U.UU5 TIr5. 51 Axis movement table 1
