This standard is a revision of 7.BJ52003-88 "Installation Shaft Diameter of Diamond Dressing Roller". The original version was formulated on the basis of analyzing the relevant data of diamond roller dressers at home and abroad, and through experimental research, combined with the characteristics of the product. Its technical depth can still meet the current scientific and technological level and meet the needs of production and use. This standard has basically the same technical contents as ZBJ52003-88, the main difference is that two specifications 12 and 52 are added in 1.
It has been revised according to relevant regulations and will replace ZBJ5213-B since its implementation. It is proposed by the National Metal Cutting Machine Tool Standardization Technical Committee and is affiliated to the National Metal Cutting Machine Tool Standardization Technical Committee. The responsible unit for this standard is Beijing Machine Tool Research Institute. This standard was first issued in January 1988. 1 Scope
