This standard specifies accuracy test requirements for heavy duty deep hole drilling and boring machines, including pre-adjustment tests, geometric accuracy tests, and working accuracy tests. It applies to machines with maximum boring diameter of 250-1000 mm and depth of 3000-20000 mm. The standard details multiple test items such as straightness and parallelism of bed guideways with corresponding tolerances, and references GB/T 17421.1 for general test methods. Compared to the 1996 version, it expands the specification range, adds test items, and adjusts some tolerances.
该标准规定了重型深孔钻镗床的精度检验要求，包括预调检验、几何精度检验和工作精度检验。适用于最大镗孔直径250-1000mm、深度3000-20000mm的机床。标准详细列出了床身导轨直线度、平行度等多项检验项目及公差，并引用了GB/T 17421.1作为通用检验方法。相比1996版，扩大了规格范围，增加了检验项目，调整了部分公差。
