Introduction of JB/T 8772.7-1998

JB/T 8772.7-1998 本标准是根据 JB/T 8771.4-1998《加工中心检验条件第 7 部分：精密加工试件精度检验》制订的（该标准等效采用国际标准草案 ISO/DIS 10791-7《加工中心检验条件第 7 部分：精密加工试件精度检验》）。在检验项目、检验方法、检验工具等内容上与 JB/T 8771.7-1998 相同，允差则在该标准基础上压缩（压缩公比约为1.6，个别压缩公比约为1.25）。本标准规定了在精密加工条件下标准试件的特征、尺寸及切削试验，用于评定机床的切削精度。本标准适用于线性轴线行程至 2000mm 的精密加工中心。
