Hi
Can anyone give me some advice on the following.
I am cutting various gears in chromium and nitriding steels.The pitch is 32DP.
We have tried to cut these parts on both Fellows and sykes shaping machines,buti cant get away from the tearing on the flanks.When turned upside down,there is severe breakout with [arts of the profile torn away.Any work arounds for this.
Thanks
Mike
