Thanks for the replies.
It is to be a one off (or low vol. at least) and is part of a precision assembly.
It will be used to wind a dowel in and out, hopefully the clearance in the threads will be greater than any variation in straightness and concentricity etc. however I feel I want to...
I am looking to get a piece of bar turned with two threads of different pitches (differential screw), there is to be an M8 and M10 thread and the piece is to be 90mm long.
Am I right in thinking run out cannot be specified as it threaded?
I want it to be very straight without specifying...
Hi
I have a design where I have one dowel and one threaded hole.
I want to work out what the tolerance on the centre distance needs to be so I need to work out how much the screw can move in the hole, as the part is being wound up and down (adjusted) on the screw.
I know this is different...
Hi
I am looking a two dowels separated by a distance D which must match up with two holes on a corresponding part.
The fit between the dowel/hole is to be a H7/g6 close sliding fit.
The max shaft diameter under this spec is 9.995, the min hole diameter is 10.000 under this spec.
Surely...
