This standard JB/T 54893-1999 specifies product quality grading requirements for double circular arc gear hobs, including AQL values, RQL values, nonconformity classification, and life test. It applies to hobs produced in batches according to GB/T 14348.1 and GB/T 14348.2. Nonconformities are classified into Class B (with three groups) and Class C, covering cracks, roughness, dimensional deviations, hardness, and other items. The life test specifies machine tools, tools, test blanks, and cutting parameters, with average life and coefficient of variation as evaluation criteria. The standard replaces JB/T 54893-93 and has been effective since January 1, 2000.
本标准JB/T 54893-1999规定了双圆弧齿轮滚刀的产品质量分等要求，包括AQL值、RQL值、不合格分类及寿命试验。标准适用于按GB/T 14348.1和GB/T 14348.2成批生产的滚刀。不合格分为B类（含三组）和C类，涵盖裂纹、粗糙度、尺寸超差、硬度等多项指标。寿命试验规定了机床、刀具、试坯和切削规范，以平均寿命和变异系数作为评定依据。标准自2000年1月1日起实施，代替JB/T 54893-93。
