BEST METHOD FOR SMALL, TIGHT TOLERANCE, HOLES
BEST METHOD FOR SMALL, TIGHT TOLERANCE, HOLES
(OP)
I need to make two .0275" holes in a .120" thick plate, with a hole diameter and centerline tolerance of +/- .00005", or better.
I was thinking of making the plate of either carbide or 440C 54-56RC.
Is jig grinding the best method for making these holes?
Is one material better than the other for the tolerances I'm trying to get?
Thanks for any input you can give me.

Is it machined in house or outside? Ask the machine shop where it will be machined if they are capable of the tolerances.

Might want to find a 'micro machining' specialist.

I recommend a material that doesn't change in size much with temperature. ;)
