JB/T 54862-1999

Quality inspection departments in tool manufacturing companies use this standard to evaluate the quality grade and assess the periodic stability of batch-produced metal slitting saws and screw slotting cutters. By specifying AQL and RQL values, it helps control nonconformity rates and ensures consistent product quality. This standard is important for guaranteeing cutting performance and service life of these tools.

刀具制造企业的质量检验部门使用本标准，对成批生产的锯片铣刀和螺钉槽铣刀进行质量等级评定和周期稳定性考核。通过规定AQL值和RQL值，本标准帮助企业控制产品的不合格率，确保产品质量稳定可靠。它对于保证刀具的切削性能和使用寿命具有重要意义。

This standard specifies quality grading requirements for metal slitting saws and screw slotting cutters, including AQL values, RQL values, nonconformity classification, and life tests. It applies to quality grade evaluation and periodic stability assessment of batch-produced products according to relevant standards. The standard details AQL and RQL values for different grades (qualified, first-class, premium), along with specific nonconformity items and judgment criteria for Class B and Class C defects. The life test section specifies test conditions, cutting parameters, wear criteria, and life indices, providing a basis for tool quality control and performance verification.

本标准规定了锯片铣刀和螺钉槽铣刀的质量分等要求，包括AQL值、RQL值、不合格分类及寿命试验。适用于按相关标准成批生产的产品质量等级评定和周期稳定性考核。标准详细列出了不同等级（合格品、一等品、优等品）的AQL和RQL值，以及B类和C类不合格的具体项目和判定依据。寿命试验部分规定了试验条件、切削规范、磨损判据和寿命指标，为刀具质量控制和性能验证提供了依据。
