Hi,
I have an aluminum plate which has been ground flat, and I would like to insert a few precision ground shafts into this plate and have them rigidly/permanently affixed in place, precisely square and perpendicular to the plate. The shafts diameters are .75" and the plate is 1" thick. The shafts will protrude 6" out and I would like it to deviate from squareness by less than .001" over the 6". The straightness of the shafts are rated at .001" per foot.
My initial idea is to bore out the holes a couple thou oversized and then loctite the shafts into place, holding them in place by clamping them to a precision ground v-block w/ .0001" squareness tolerances. Or I could beuild a fixture to adjust the tilt and and measure the squareness with a squareness gage, but I'd have to buy one.
Does this sound like a good idea to anyone? I have a Fadal 4020 VMC and I suppose I could square the plate to the quill and bore for a press fit, but I'm not sure if I could ensure that the shaft would go in straight. If it didnt then I'd be upset, and we wouldn't want that.
Thanks for any advice.
