What does it mean to drill holes for flange bolts?
Thread Content
Hello, fellow craftsmen. Recently, I came across a note in some incomplete drawings that mentioned \"drilling holes for flange bolts\". I would like to ask you all what this phrase means How should one understand matching drills? Thank you!
The requirement to drill the flange bolt holes in pairs means that for flanges intended to be installed together, it is necessary to ensure that the spacing and position of the bolt holes, as well as their diameter, are all consistent, thereby facilitating installation. During the processing of the flanges, these elements are fixed together using fixtures before machining.
