Scope

Scope: This standard specifies the models, parameters, general requirements, accessories and tools, safety and hygiene, processing and assembly, and air running test of portable tap grinders. This standard applies to portable tap grinders for grinding M4 to M42 taps. Main technical content: The scope of application of the standard is defined as portable tap grinders with a maximum grinding milling cutter diameter of 4 mm to 42 mm. By formulating this standard, the following main issues are addressed: (1) There is a lack of enterprise-level or higher product standards for tap grinders, and the product standards of various enterprises are not publicly available, leaving users of tap grinders without advanced standards to compare the advantages and disadvantages of commercially available products. (2) Provide standardized accuracy testing methods and judgment criteria for tap grinders. The accuracy requirements proposed in the standard represent the advanced technical level in China.
