Can you give me some advices as I have to shorten and reduce the shaft diameter of a motor?!
It seems that the material used is extremely hard.
Of course I've seen videos that shows to use a plastic bag with tape to prevent iron fillings to be attracted by the magnets.
But what tool to use and how to have a very clean and well done work?!
The shaft is 10mm dia and I have to reduce it to 8mm as precisely as possible.
Original shaft is 10mm +0 -0.007mm!!!
Concentricity is also a concern, and I cannot remove the shaft which is pressfitted.
Have a Nice Day.
