How thick is it axially? If it's pretty thin it should be sandwiched between two pieces of softer metal. Go slow on the feed, high on the speed to make a lot of shallow passes with a slightly narrow cutter. Then use a full width cutter for a single full depth pass to clean up the slot sides.
I'd also make a bandsaw cut to near full depth in each slot to reduce the amount of material for the cutter to remove and provide a path for lube to get in/out.

The slots are 45 mm deep and 6 mm wide, the rotor is made of 4140 steel (I attached a basic picture of the rotor). I could purchase the hss disk cutter off course, but if I can get away with welding and grinding my own tool it would be great because those cutters aren't cheap and I'll be only using it for this job only. The problem is, I'm afraid the carbide cutter will break soon making all this process a waste of time. What do you think? _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
