I need to make some hardened gears. These are small spur gears, 2 - 3 inch diameter with keyways in their bores. I don't have a spec on hardness or alloy, just something with good wear properties. I will cut them on a 4th axis on a CNC mill. Current thinking is to make them slightly over thickness and slightly under bores and finish grind, but I have no way to grind the teeth, so it needs to be a steel with good machining properties and minimal growth, shrink, or distortion.
I have heard of hones that will work with a keway but have no experience with them. I have a Sunnen MBB 1600 hone, so that is a possibility for the bores.
Suggestions?
