GB/T 4685-2007External cylindrical grinding machines -- Testing of the Accuracy (English PDF)

Foreword

This standard is identical with ISO 2433:1999 "mobile worktable universal cylindrical grinding machine accuracy test Test conditions" (English Chinese Version).

This standard is equivalent translation ISO 2433:1999.

For ease of use, this standard made the following editorial changes.

--- In order to be consistent with other standards, the standard name will be changed to "cylindrical grinding machine accuracy test";

--- Remove the foreword and introduction of ISO 2433-1999;

--- "This International Standard" be replaced by "this standard";

"." --- With a decimal point instead of a decimal point, "";

--- To ISO 2433:1999 and other international standards referenced with have been adopted in place of the corresponding international standard for our country standard;

--- Increasing the reference standard GB/T 19660-2005;

--- Remove the ISO 2433:1999 Foreword and Introduction;

--- Deleted Chapter 1, "note" of the content;

--- Remove the "Found bias" Tolerance a column;

--- Delete the contents of "Appendix A" of;

--- Remove the "reference standard." this standard replaces GB/T 4685-1994 "Cylindrical Grinder precision." Compared with GB/T 4685-1994, the main changes are as follows.

--- Increased Chapter 2, "Normative references";

--- Increased Chapter 3, "explained the terms and axis name";

--- Added "Geometric tests" in the G2, G8, G9, G13, G14, G15, G16 entry canceled G1 items;

--- Increased Chapter 7, "positioning accuracy and repeatability";

--- Abolition of the "pre-tune test" content;

--- Abolition of the "precision work" in the P3, P4, P5 items.

And supporting this standard criteria used are.

--- JB/T 7418.2-1994 "cylindrical grinding machine technical conditions." the standard proposed by China Machinery Industry Federation.

The standard metal cutting machine tools by the National Standardization Technical Committee (SAC/TC22) centralized.

This standard was drafted. Shanghai Machine Tool Works.

1 Scope

This standard specifies the general-purpose ordinary precision moving table type cylindrical grinding machine, universal cylindrical grinder cylindrical grinder and end of a few He accuracy, precision and positioning accuracy of the work axis repeated positioning accuracy of test methods and corresponding tolerance.

This standard applies to the maximum grinding diameter 50mm ~ 800mm, maximum grinding length of 150mm ~ 4000mm outside the ordinary level precision Grinder and universal cylindrical grinder and a maximum grinding diameter 50mm ~ 500mm, maximum grinding length of 150mm ~ 3000mm General Level precision face cylindrical grinding machine.

This standard applies only to machine accuracy test, does not apply to the operation to check the machine (such as climbing vibration, abnormal noise, moving parts Line, etc.), or machine-parametric tests (such as speed, feed rate, etc.). These tests should be carried out before the inspection accuracy.
