Ohhhh boy I need to machine a fun part. It is a rocket fuel injector for a liquid fuel rocket. The initial part was made additively using Inconel 718, and naturally it was sintered in the oven, and then stress relieved during heat treating. So this shit is hard and tough.
Rockwell 40-45.
All that really needs to be done is post process, which consists of face milling and then cutting grooves. Facing is fine, ill survive.
I want a tool that can handle the groove milling operation...I have looked at Harvey tools for their keyseat mills but I honestly don't know if those will be able to handle this. The geometry of this part clearly makes turning impossible, otherwise I would just use a ceramic insert groove tool.
Any other vendors you can think of that will give a superalloy keyseat/groove mill tool that can stand up to this heat??? Grooves are 0.1 inch tall and 0.05 deep.
