GB/T 18400.2-2010Test conditions for machining centre -- Part 2: Geometric tests for machines with vertical spindle or universal heads with vertical primary rotary axis (vertical Z-axis) (English PDF)

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);

--- Part 2. Part 2. Vertical spindle head or universal Geometric tests for machines with vertical primary rotary axis (vertical Z-axis);

--- 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 2.

This part identical with ISO 10791-2. universal vertical or with vertical primary rotary axis 2001 "Test conditions for machining centers - Part 2 Geometric tests for machines spindle head (vertical Z axis) "(in English).

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.

This section of the Appendix A, Appendix B and Appendix C are normative appendix.

This part is proposed by China Machinery Industry Federation.

This part of the National Metal Cutting Machine Standardization Technical Committee (SAC/TC22) centralized.

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.
