This standard specifies methods for quality grade evaluation and periodic stability assessment of machine reamers, including AQL values, RQL values, classification of nonconformities, and life test. It applies to machine reamers produced in batches according to relevant national standards. Products are classified into qualified, first-grade, and premium-grade, with strict AQL and RQL indicators for each grade. The life test requires 40Cr steel workpieces, conducted on a vertical drilling machine, with specified cutting parameters, cooling conditions, and failure criteria. This standard provides a systematic technical basis for quality control of machine reamers.
