high speed machine

[MCFELIX]

hello members I need to machining a inconnel material 718 I need to run the tool between walls the tool I can fit in between walls is 3/8 the block is 3.0 square and need to machining to .350 thausand base I think high speed tollpaht ,anybody have previous experience

Inconel and Highspeed DO NOT go together

[MCFELIX]

really ,is alot material to cut

[Guest]

It is machinable but I have found that you must take your time to do it.

 

Most carbide endmills will be cutting a SFM of around 70-90 SFM, that figures out to around 815 RPM, at a feed rate of 4.89, DOC around .06m radial step over of .25

 

And water soluable coolant is probably NOT your best bet.

waooo sound like alot time for cycle time

[crazy^millman]

Well sorry but it si not Alum I might try a rouger and rough it within .02 then finish from there.

I'm gonna go on ahead and predict some busted up tooling here....

Yeah, your first exotic alloy job is gonna cost ALOT in screwed up tooling. Those Superalloys have ZERO forgiveness if you are even the least bit wrong.

 

If you can, run ceramic tooling, that will net you the highest SPM but it still very slow relative to even say 4130 and VERY pricey.

 

Good luck.

thanks for all the inputs ,yes maybe is only one way to go, i will post the part tomorrow in the ftp for more information if somebody recomend tools for this part

Didn't Hardmill put up a video running inconnel at 3000 sfm using ceramic inserts?
