Preface
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 7925-2005 "Parameters of Wire EDM (Reciprocating Wire Type)", compared with GB/T 7925-2005,
The main technical changes are as follows.
---Modified the main content and scope of application of the standard (see Chapter 1, Chapter 1 of the.2005 edition);
---Modified the machine tool type and listed a separate chapter (see Chapter 4, Chapter 4 of the.2005 edition);
---Modified the parameter range of X, Y, Z axis stroke, maximum workpiece quality, and maximum cutting thickness; "Maximum cutting taper" was changed to "Maximum
Cutting slope" and modified the parameter range (see Table 1,.2005 edition of Table 1).
This standard was proposed by the China Machinery Industry Federation.
This standard is under the jurisdiction of the National Standardization Technical Committee for Special Processing Machine Tools (SAC/TC161).
Drafting organizations of this standard. Suzhou Electrical Processing Machine Tool Research Institute Co., Ltd., Hangzhou Huafang CNC Machine Tool Co., Ltd., Jiangsu Dongqing CNC Machine
Bed Co., Ltd., Suzhou Baoma CNC Equipment Co., Ltd., Taizhou Jiangzhou CNC Machine Tool Manufacturing Co., Ltd.
The main drafters of this standard. Wang Ying, Zhang Xudong, Li Haozhou, Mei Jianen, Ding Chengcai, Wu Yue.
This standard was first published in June 1987, and was revised for the first time in May.2005.This is the second revision.
