Foreword
GB/T 18400 "Test conditions for machining centers" is divided into ten parts.
--- Part 1. horizontal spindle and with head Geometric tests for machines (horizontal Z-axis);
Universal spindle head Geometric tests for machines (vertical Z-axis) or vertical with vertical primary rotary axis;. --- Part 2
--- Part 3. with horizontal rotary axis of the main spindle head overall universal Geometric tests for machines (vertical Z-axis);
--- Part 4. positioning accuracy and linear and rotary axes repeatability test;
--- Part 5. Clamp the workpiece pallet positioning accuracy and repeatability of positioning accuracy test;
--- Part 6. feed rate, speed and accuracy test interpolation;
--- Part 7. finishing accuracy test specimen;
--- Part 8. Evaluation of the contouring performance in the three coordinate plane;
--- Part 9. Evaluation of conversion tool changer and pallet operation time;
--- Part 10. Evaluation of thermal effects.
This section GB/T 18400 Part 7.
This part identical with ISO 10791-7.1998 "Test conditions for machining centers - Part 7. Finishing accuracy test specimens" (English
Chinese Version).
Taking into account China's national conditions, in the use of ISO 10791-7.1998 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 10791-7.1998 Foreword and Introduction, increasing the national standards foreword;
--- Remove the ISO 10791-7.1998 Annex A (informative).
This part is proposed by China Machinery Industry Federation.
This part of the National Metal Cutting Machine Standardization Technical Committee (SAC/TC22) centralized.

Test conditions for machining centers
Part 7. Finishing accuracy test specimen
1 Scope
GB/T 18400 provisions of this part of the finishing conditions under standard test piece of a series of cutting inspection requirements, as well as the specimen itself
Features and dimensions. This part can be used as cutting precision machining centers assessing the basic requirements. Under the agreement the supplier/manufacturer and users,
It can be different and more rigorous test.

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 expressed as a ratio. In some cases the sake of clarity, but also with microradians (μrad) or arcsec ( ") indicates its conversion off
Department of the formula below.
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, especially empty running accuracy testing before installation, and other components of the spindle
Warming, test methods, precision test tools.
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
Test any order.
3.4 Test Project
When the test machine, according to the structural characteristics must not test all of the items in this section. When testing requirements for acceptance purposes, can
Made by the user to select the manufacturer agreed number of interested test items, but these items must be clearly stated at the time of ordering the machine.
3.5 inspection tool
Test tools under this Part of example only. You can use the same amount of instructions and other inspection tools to at least the same accuracy.
Indicators should have a 0.001mm or higher resolution.
Type 4 test pieces
It offers two types in this section, and each type has two specifications of the test piece. Type, size and marking specimens in Table 1.
In principle, at the time of acceptance of each specimen should be processed only one. In the case of special requirements, such as performance statistics assessed the machine, according to the system
