    Deep hole processes

    MikeHalloran, There are three dowel holes to counteract torsional loads during the winding process. Is it really overconstrained? If the holes were drilled through each plate separately, then yes, but as they're done while the whole thing is clamped together, shouldn't it just be like...

    Deep hole processes

    Having previously posted the "surface grinding/lapping" thread, I have been convinced by my design group that the topics discussed in there were dead ends. I'm now investigating an alternative method of meeting the tolerances in question. To re-cap, I'm trying to make a laminated...

    Surface grinding/lapping

    unclesyd, Obviously a drawing would be ideal in the circumstances, but I'm only a graduate, so a little wary of giving away anything I shouldn't... There are two magnets facing each other, 2m long and the surfaces in question are 80mm wide. The magnets are made up of alternating poles and...

    Surface grinding/lapping

    Thanks to all for the replies, some hugely useful info there. BillPSU: That's a really good point about the material. We'll be using as close to pure iron as possible, so transfer of particles may be a problem. I'll have to follow that one up. MikeHalloran: The magnet will be supported at...

    Surface grinding/lapping

    I'm designing a laminated superconducting magnet which is 2m long, made up of around 250 individual plates. The required flatness of the pole pieces across the length is 10 microns. Our original idea was to join all the magnet plates together using dowels, controlling the location of the dowel...
