Hi,
I'm about to make a low serie of performance gearbox gears. And my question is to you gear mfg guys out there. If there is a better way than for example wire edm the gear in EN36 steel and then send it out to case hardening, and then shootpeen it. With todays special steels would it be possible to use a more expensive steel that could be through harded before the wire edm and that way have better precision due to no distortion from hardening process?
Don't say gear hobbing shaving etc. This is not about time. its becouse I have a decent makino wire edm and time is not a problem. And the material price is not very sensitive either.
How much distortion would a case hardning do? What class gears should I expect? I mean this way it shuld be as good as hobbing and then case hardning. My idea was to shootpeen them to avoid cracks from the edm surface.
Anyone with input on this?
