Summary: This standard specifies the geometrical accuracy requirements and methods and their corresponding tolerances for general purpose inverted CNC vertical lathes and inverted vertical turning centers. This standard explains the different concepts, different configurations and general characteristics of inverted CNC vertical lathes and inverted vertical turning centers, and gives the terms and definitions of the control axes (see Figures 1, 2, 3 and 4). This standard applies to the accuracy of machine tools. This standard does not apply to machine tool inspection (such as vibration of the machine, abnormal noise, crawling of moving parts and other tests) and machine tool characteristics (such as speed, feed), because these tests are usually carried out before the accuracy test.

Foreword

GB/T 16462 "CNC lathe and turning center inspection conditions" is divided into eight parts. --- Part 1. Horizontal machine geometry accuracy test; --- Part 2. Vertical machine geometry accuracy test; --- Part 3. Inverted vertical machine geometry accuracy test; --- Part 4. Linear and rotary axis positioning accuracy and repeat positioning accuracy test; --- Part 5. Feed, speed and interpolation accuracy test; --- Part 6. Precision test precision test pieces; --- Part 7. Evaluation of the contour characteristics in the coordinate plane; --- Part 8. Assessment of thermal deformation. This section GB/T 16462 Part 3. This section drafted in accordance with GB/T 1.1-2009 given rules. This section uses the redrafted law revision using ISO 13041-3.2009 "CNC lathe and turning center inspection conditions Part 3. Down Vertical machine tool geometric accuracy test. " This part of ISO 13041-3.2009 technical differences and the reasons are as follows. --- Chapter 4 title "brief description" to "general requirements", after the change in line with national conditions and with the current standards of similar CNC machine tools uniform; --- In the accuracy of the test table to delete the "measured deviation" column, because "measured deviation" is usually in the machine "certificate of conformity or accuracy Single "appears, there is no need to appear in the standard, after the change in line with national conditions and with the current standards of similar CNC machine tools unified; --- Chapter 6 of the International Standard will be replaced by this section Appendix A (informative), because the sixth chapter of the International Standard test items immature, No test indicators, so this section will be Chapter 6 as a reference test items in this part of the Appendix A, after the change In line with national conditions and with the current standards of similar CNC machine tools uniform; --- International Standard Appendix A to Appendix B of this section, because the International Standard Chapter 6 to Appendix A of this section, so the International Standard appendix A to appendix B of this section. This part is proposed by China Machinery Industry Federation. This part of the National Standardization Technical Committee metal cutting machine (SAC/TC22) centralized.

1 Scope

GB/T 16462 of this part of GB/T 17421.1 and ISO 230-7 provides for general-purpose inverted CNC vertical lathe and pour Geometrical inspection requirements and methods for vertical turning centers and their corresponding tolerances. This section explains different concepts, different configurations and common features of inverted CNC vertical lathes and inverted vertical turning centers, and gives Control axis terms and definitions (see Figure 1, Figure 2, Figure 3 and Figure 4). This section applies to the accuracy of machine tools. This section does not apply to the operation of the machine inspection (such as machine vibration, abnormal noise, crawling and other moving parts test) and machine tools (Such as speed, feed rate), because these tests are usually carried out before the accuracy test.
