We are about to start a huge production run of a piece made from the material MP35N- Ni35 Co35 Cr20 Mo10.In my experience I have always found solid carbide tooling and the right speeds and feeds combination to be the ticket to machining materials of this type. However our engineers would like to approach this using diamond coated tooling to machine this material and I am not so sure about this.The piece is very small has a thin wall and very tight tolerances. .04id x .05 od x .135 long and we have to make 10's of thousands of them. This will be done on a swiss machine. Will diamond tooling be the approach to take to achieve optimum tool life and tolerance control with this type of material or is carbide the way to go? Thoughts and suggestions? Thank you in advance
