Hey guys take a look at this part and tell me what you think is the best way to make it I have been trying to make this part happen I can run it in aluminum but when I try in stainless It destroys my internal tooling ( chamgroove ) solid carbide, I have tryed several different types of tools and get the same results with all I am running the tooling as per ISCARs recommendation but still no Joy. The Iscar rep said that I have the tool too high but I dont see how thats possible with the tool and holder having flats on them the I.D. on this part is min .533 max .680 I have double checked the tools to make sure that I have enough to do the features and all seems to be O.K. I think my problem in stainless is I have no way to evacuate the chips and they are getting cought behind the grooving tool and crowding it but I could be wrong somebody please tell me what they think. I am fairly new to Mazak but seem to be able to program it pretty well and like I said I can get a good aluminum part. The stainless is 304, thanks for your input and I hope the attachment works Hey guys take a look at this part and tell me what you think is the best way to make it I have been trying to make this part happen I can run it in aluminum but when I try in stainless It destroys my internal tooling ( chamgroove ) solid carbide, I have tryed several different types of tools and get the same results with all I am running the tooling as per ISCARs recommendation but still no Joy.
