This standard JB/T 5245.3—2011 specifies the geometric accuracy requirements and inspection methods for light type bench drilling machines, applicable to such machines and their variants. It covers general requirements (units, leveling, inspection sequence, etc.) and geometric accuracy inspection items (flatness of base and worktable, radial runout of spindle, perpendicularity of spindle axis to base/worktable, perpendicularity of spindle sleeve movement, etc.). Each item includes tolerance, inspection tools, and method. The standard references GB/T 17421.1 for general inspection principles.
