1 Scope

GB/T 14328-2008 is the Chinese national standard on roughing end mill, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 3 June 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2009.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the straight shank roughing end mills, Weldon shank roughing end mills, Morse taper shank roughing end mill of the type and scale Inch, tag example, technical requirements, marking and packaging. This standard applies to 6mm ~ 50mm diameter straight shank roughing end mills, diameter of 8mm ~ 63mm Weldon shank roughing End mills and diameter 10mm ~ 80mm Morse taper shank roughing cutter.
