Summary: This standard specifies the horizontal (ie the horizontal axis is) machining centers (CNC sharp bed or applicable, CNC anxiety bed) geometric accuracy test. This section applies to basically have four CNC axes, three linear axes (X, Y, Z). Stroke to 2 000 mm and a rotation axis (B ") horizontal machining center is also applicable to sliding spindle, slide. pillow or three different forms of additional movement additional universal spindle head in the appendix of this section lists three possible additional test items universal spindle head: Appendix a (normative): 45 pairs of spindle indexing head, mechanical indexing has two objects at different angular positions of the corresponding test items (AG1 ^-AG9) only checks the last position in which the spindle, Annex B (normative): rotary spindle head, with two mutually perpendicular CNC rotary axis (test items BG1 ^-BG7), Annex C (normative): 45 points in a row for indexing spindle head, similar to the first form, but with two consecutive NC rotary indexing axis, the corresponding test items (CG1-CG7) to check all the geometric characteristics of the spindle which last position (plane and axis), except for the two rotary axis positioning accuracy, If it tight to allow movement and the town, which can be used for 45 test items for points. spindle head to do a deeper human trials. this section applies only to geometric accuracy test machine, does not apply to the movement of the machine tool accuracy test. normally these two tests are carried out separately in the no-load or finishing conditions machine Some other tests will be included in the GB/T 18400 in other parts.

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 1. This part identical with ISO 10791-1.1998 "Test conditions for machining centers - Part 1. horizontal spindle and with head machine geometry Accuracy test (horizontal Z-axis) "(in English). Taking into account China's national conditions, in the use of ISO 10791-1.1998 when this part has made several editorial changes. --- "This standard" be replaced by "this section"; --- Chapter 4, the heading "brief description" to "General requirements"; --- Remove the ISO 10791-1.1998 Foreword and Introduction, increasing the national standards foreword; --- Remove the ISO 10791-1.1998 Annex D (informative). 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. This section is drafted. Beijing First Machine Tool Plant, Shenyang Machine Group Kunming Machine Tool Co., Ltd., Beijing Machine Tool Research Institute, Sichuan Changzheng Machine Bed Group Co., Ltd., Shenyang Institute of boring machine.

1 Scope

GB/T 18400 provisions of this part of the horizontal (ie horizontal Z axis) machining centers (or applicable CNC milling, CNC boring machine, etc.) Geometric tests. This section applies to essentially have four CNC axes, three linear axes (X, Y, Z) and a return trip to 2000mm Rotation axis (B ') of the horizontal machining center. Also applies to spindle slide, additional movement of the ram or three different forms of additional universal spindle head. This section lists three possible test items additional universal spindle head in the appendix. --- Appendix A (normative). 45 ° mechanical indexing of the minutes of the spindle head, with two objects of different angular positions of the corresponding inspection Test project (AG1 ~ AG9) checks only the last position in which the spindle; --- Appendix B (normative). rotary spindle head having two mutually perpendicular NC rotary axis (test items BG1 ~ BG7); --- Appendix C (Normative Appendix). 45 ° to divide the continuous indexing spindle head, similar to the first form, but with two NC rotary axis All geometric properties of continuous indexing, the corresponding test items (CG1 ~ CG7) To check the influence of the last position in which the spindle (plane And except axis), two rotary axis positioning accuracy; if their movement and allow locking, these test items can be used for sub-45 ° Spindle head to do more in-depth testing. 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.
