Hi All,
I have 17mm dowel with a H7/g6 fit. However the parts do not want to play ball, I can't even get the dowel started.
The manufacturing engineers of the supplier tell me the hole is drilled and reamed with a 17H7 reamer and checked with a bore gauge.
The dowel is ground to g6.
So any ideas whats happening? My suspicion is the hole is not correct, the dowel seems about right when checked with a mic. I don't have access to anything to check the bore really.
Is it possible the hole is out-of-round or thee is some other kind of form error? No geometric controls exist on the drawing other than the H7 size requirement.
Any pointers?
Thanks.
