Thanks for the replies everyone. Gearcutter, We have 3 fellows shapers, one is a 6a, but the gears are too big to go on this machine to check. But we have a couple of sunderland planers that we will be cutting the gears on. Could you explain more about your method of checking the helix angle...
Hi all. First I would just like to say what a great site this is.
I work for a small jobbing shop doing gear cutting.
We have a job on at the moment for which I have the sample pair of helical gears. Usualy we put them on a profile and lead tester to determine the helix angle, but unfortunately...
