      Hi,
      Our company designs machines for the mining industry, ususally parts are very big and heavy. We have a nut with a M450 thread wich when disassebled has a tendency to seize. This results in the maintanance personell to have to burn or vut away the nut.

      We have discovered that running a steel wire brush on the threads removes most burr and rounds of the threads enough that risk of seizing significally reduced. We want the force our suppliers to use a wire brush to deburr the thread but my problem is how do I mark this on the drawing?

      We want to force them to use a wire brush and also to do it with a certain pressure to acheive the same results every time.

      Does anyone have any experiance of this or any suggestion what to put on the drawing?

      Write a work instruction describing exactly what type of brush to use and how to use it, and add a note to the drawing saying, "deburr per work instruction such-and-such."
