Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is used instead of GB/T 6119.1-1996 "Three-blade cutter type and size" and GB/T 6119.2-1996 " Knife technical conditions ".

The main changes in this standard compared with GB/T 6119.1 and GB/T 6119.2 are as follows.

- merge the two parts of the original standard into one standard;

--- canceled the GB/T 6119.2-1996 in the "Chapter 6 performance test";

- Amend the original standard "Appendix A (Reference)" to "Appendix A (Normative Appendix)".

This standard uses the re-drafting method to modify the use of ISO 2587. 1972 "with straight hole and plain key transmission of the three-edge cutter milling system" (English version).

This standard has the following editorial changes and technical differences as compared with ISO 2587. 1972, and the terms involved in these differences have been the vertical single line (-) of the position on the outside margin is marked.

--- Added "4.2 mark example";

--- increased the "location tolerance, appearance and surface roughness, materials and hardness, marking and packaging" and other technical requirements of the project;

--- Added "Appendix A (normative appendage) three-edge cutter round beating detection method".

This standard is proposed by the China Machinery Industry Federation.

This standard is under the jurisdiction of the National Tool Standardization Technical Committee (SAC/TC91).

This standard is responsible for the drafting unit. Wenling Wenxi Engineering Cutting Tool Technology Service Center Co., Ltd., Chengdu Tools Research Institute Co., Ltd.
