The problem with these parts is that there is literally THOUSANDS of them being made every week, and only hundreds going out after deburring. The ones that can be held in a lathe are being deburred that way, but internal splines and difficult to hold/reach components are having to be manually deburred.
I also believe that using the nylon impregnated deburring brushes is a no-no for these parts as they are aerospace, and surface finishes of the adjacent features is critical.
You say that a sharp tool will leave an easier to remove burr, but is there any tool material which could be used to provide a sharp edge for longer when cutting steel? Diamond coating maybe? I'm more used to cutting aluminium, so carbide all the way for me, with HSS when I can get away with it. |
