Foreword

GB/T 16462 "CNC lathes and turning centers Test conditions" is divided into eight sections. --- Part 1. Horizontal Geometric tests for machines; --- Part 2. Vertical Geometric tests for machines; --- Part 3. Geometric tests inverted vertical machine; --- Part 4. linear and rotary axes positioning accuracy and repeatability of the test; --- Part 5. feed, speed, and interpolation accuracy test; --- Part 6. finishing accuracy test specimen; --- Part 7. Evaluation of contouring performance in the coordinate plane; --- Part 8. Evaluation of thermal deformation. This section GB/T Part of 416,462. The partial modification of the use of ISO 13041-4.2004 "CNC lathes and turning centers seized Test conditions - Part 4. linear and rotary axes positioning accuracy and repeatability test "(in English). This part of ISO 13041-4.2004 compared to the main technical differences are. --- Increasing the linear axis travel greater than 2000mm machine positional accuracy of the testing methods and the positional accuracy tolerance values. For ease of use, this standard made the following editorial changes. --- "This standard is the word" to "this Part"; --- Chapter 4, the heading "Notes" is replaced by a brief description; --- With a decimal point '. 'Instead of a comma as the decimal point,' '; --- Of ISO 13041-4.2004 and other international standards referenced with has been adopted as our national standard in place of the corresponding international standard; --- Remove the International Standard ISO 13041-4.2004 Foreword and Introduction. This Part replaces GB/T 16462-1996 "CNC horizontal lathe accuracy test" in the positional accuracy of the test items. 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. Shenyang CNC machine tools limited liability company. The main drafters of this section. Zhu Qian Jing, Liu Sufen. This part of the standard replaces the previous editions are. --- GB/T 16462-1996 "positional accuracy test" section. CNC lathes and turning centers Test conditions Positioning accuracy and linear and rotary axes. Part 4 Repeatability test

1 Scope

This section GB/T 16462 specifies the general linear positional accuracy levels of precision CNC lathes and turning centers and rotary axes Inspection and position accuracy tolerance values. Bit This section applies to CNC lathes and turning centers of the linear axis (travel to 2000mm) and the axis of rotation (stroke to 360 °) of Positional accuracy test. Linear axis greater than 2000mm CNC lathes and turning centers and test methods can also be specified in the provisions of this section Refer to the positional accuracy of the value of tolerance. This portion of the reference of GB/T 17421.2-2000, therefore, GB/T 17421.2-2000 environmental conditions have been described, the machine Temperature and measurement methods in this section will not be repeated.
