GB/T 18400.4-2010Test conditions for machining centre -- Part 4: Accuracy and repeatability of positioning of linear and rotary axes (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);

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 Part of 418,400.

This part identical with ISO 10791-4:1998 "Test conditions for machining centers - Part 4. Positioning precision linear and rotary axes and repeatability test "(in English).

Taking into account China's national conditions, in the use of ISO 10791-4:1998 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 10791-4:1998 Foreword and Introduction, increasing the national standards foreword;

--- Remove the ISO 10791-4:1998 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.

1 Scope

GB/T 18400 provisions of this part of the machining center positioning accuracy of linear and rotary axes and repeatability test tolerances.

This section applies to linear axis stroke to 2000mm and machining centers with the axis of rotation.

This section is no longer involved GB/T 17421.2-2000 already specified environmental conditions, warming the machine and test methods.
