机械工业部部标准JB2670-82“金属切削机床精度检验通则”对机床几何精度和工作精度检验的定义、检验方法与检验工具的使用、确定公差的一般原理等予以标准化。在机床检验中,贯彻JB2670-82是保证机床质量的措施之一。贯彻JB2670-82的含义在于:设计符合其定义的检验方案,按确定公差的一般原理进 Standard JB2670-82, “General Rules for the Inspection of Precision Machines for Metal Cutting Machines”, defines the inspection of geometric accuracy and work accuracy of machine tools, the use of test methods and inspection tools, and the general principles of determining tolerances. In the machine test, the implementation of JB2670-82 is one of the measures to ensure the quality of the machine. The meaning of implementing JB2670-82 lies in: Designing the inspection plan according to its definition, according to the general principle of determining the tolerance
