Taking into account China's national conditions, in the use of ISO 10791-2.2001 when this part has made several editorial changes.
--- "This standard" be replaced by "this section";
--- Title Chapter 3, "a brief description" to "General requirements";
--- Remove the ISO 10791-2.2001 Foreword and Introduction, increasing the national standards foreword;
--- Remove the ISO 10791-2.2001 references.

Test conditions for machining centers
Part 2. vertical or vertical rotary axis of the main belt
Universal spindle head Geometric tests for machines (vertical Z-axis)
1 Scope
This section GB/T 18400 specifies the vertical (ie. vertical Z axis) machining centers (or CNC milling, CNC boring machine, etc.) geometric accuracy
test.
This section applies to basically have three CNC axes, namely three linear axes (X, Y and Z) to 2000mm vertical machining
Heart, also applies to the ram, or additional movement of the sleeve universal spindle head, such as. the rotation axis (A ', B', and C ').
This section lists the possible additional optional horizontal axis and the two kinds of additional universal spindle head test items in the appendix.
--- Appendix A. optional horizontal axis (test items AG1 ~ AG6);
--- Appendix B. Rotary swing spindle head having a CNC rotary axis (test items BG1 ~ BG2);
--- Appendix C. rotary spindle head having two mutually perpendicular NC rotary axis (test items CG1 ~ CG7).
This section applies only to machine geometric accuracy test, does not apply to the movement of the machine accuracy test. Normally these two tests are
Performed separately. Under no-load or finishing conditions of the machine some other tests will be included in GB/T 18400 in other parts.
2 Normative references
The following documents contain provisions which, through reference GB/T 18400 in this section constitute provisions of this section. For dated reference documents
Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section
Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this
section.

3 General requirements
3.1 Units of measurement
In this section all linear dimensions, tolerances and corresponding tolerances in millimeters (mm); the size of the angle in degrees (°), the angle
Deviations and corresponding tolerance as a ratio, but in some cases for clarity available microradians (μrad) or arcsec ( ") indicates Expressions
Equivalent relationship is as follows.
0.010/1000 = 10 × 10-6 = 10μrad≈2 "
3.2 reference standard
This section should be used with reference to GB/T 17421.1-1998, particularly liter machine testing before installation, spindles and other moving parts
Recommended temperature accuracy, testing methods and tools.
GB in Chapter 4 and Appendices A to C of "test method" column, should be consistent with the description of the test reference/T 17421.1-
In 1998 the provisions of the corresponding section.
3.3 Test order
This section lists the order of test items and does not represent the actual test sequence, in order to facilitate assembly and disassembly and inspection tool inspection, press
