Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 7926-2005 "WEDM (Reciprocating traveling type) - Testing of the accuracy."
This standard compared with GB/T 7926-2005, the main changes are as follows.
Name --- standard has been modified;
--- Without reducing the technical requirements, no formal adoption of international standards;
The main components of the machine --- English term control deleted 2005 edition of French and German, retaining only the English (see Chapter 3,
Chapter 3 of the 2005 edition);
--- Figures 1, 2 to redraw, Tables 1 and 2 have been adjusted (see Chapter 3, Section 3 of the 2005 edition);
--- "Description" to "requirements", the contents vary (see Chapter 4, 2005, Chapter 4);
--- Increase the test items "Z-axis movement and a) X-axis movement; b) to check the verticality between the Y-axis movement." (See Chapter 5
G4);
G4);
--- 2005 version of the G5 changes to G8 (see Chapter 5, Chapter 5, 2005);
--- Remove the 2005 edition of the G6 (see Chapter 5, 2005);
--- 2005 edition of the G7 and G8 and G9, respectively change G10 (see Chapter 5, Chapter 5, 2005);
--- "Wire storage tube axis radial runout inspection" with "wire storage tube axial movement within the whole beating a) a horizontal plane;. B) a vertical plane"
--- Project "positive Octahedron workpiece size deviation and surface roughness inspection a) the size of the deviation on a longitudinal section; b) a cross-section
The size of the deviation; c) surface roughness. "To" positive Octahedron workpiece dimensional accuracy and surface roughness inspection a) longitudinal and transverse
Section nominal size limit deviation; b) longitudinal and cross-sectional size of the difference; c) surface roughness. "Technical requirements have been modified (see para.
--- Project "Positive octagonal table and workpiece size bias large end taper deviation checking a) the size of the big end of deviation;. B) taper deviation" more
To "positive octagonal table workpiece size difference and the large end taper deviation checking a) the difference between the size of the large end; b) taper deviation." Technical requirements do
--- Remove the Appendices A and B (see the 2005 edition of Appendix A and Appendix B).
The standard proposed by China Machinery Industry Federation.
The standard machine tools by the National Standardization Technical Committee (SAC/TC161) centralized.
This standard was drafted. Suzhou EDM Machine Tool Research Institute Co., Ltd., Suzhou Sanko Technology Co., Ltd.
The main drafters of this standard. Ye Jun, Yu Zhi three Qiuyu Xiu, Wang Ying, Xu, Lu Dawei, high Ye.
This standard replaces the standards previously issued as follows.
--- GB/T 7926-1987, GB/T 7926-2005.
CNC wire EDM wire cutting back and forth go
Machine accuracy test
1 Scope
This standard specifies a numerical control cutting reciprocating forming geometric precision wire walking WEDM inspection, CNC axis positioning accuracy
And repeat positioning accuracy testing and inspection process, but also provides the above-mentioned test corresponds to the value of tolerance.
This standard also specifies the name of the main components of the machine, and with reference to GB/T 19660-2005 named axis.
This standard applies to a reciprocating cutting shaping CNC wire walking WEDM, including cross-table and single column machines
Double column machines (hereinafter referred to as. the machine).
