What kind of bits cut something that hard?

Ceramic or diamond

The ones saying it should be easy must be the engineers that drew the prints....

Try one using some brushed on oil.

If it was easy your wife's sister's whiny brother-in-law could do it.

Everyone thinks all parts are easy in the “magic box” lol

Yep, just "CNC" it. ( or better yet just C&C it )

[kruppa24]

If that don't work, do that.

Hone it bro!

Hay now that's my Dad.

I am on CNC and it still sucks. Got 1 down. 5 to go.

I know you are. I was joking. That was the response I heard a lot from customers when I was running machines.

If it comes in under, just keep taking a little off at a time til you get it right...........

Grind it baby. .0001" on a turned or bored surface is insane. Plus it depends on what the diameters and lengths are.

I used to turn parts that had a .+/- .0005 tolerance all the time and have had to hold +/- .0002 several times. But not on chrome molly! . On part like that, we would leave them about .003 over and send them to the grinder.

Why aren’t they rough turning and grinding?

The O.D. grinders get all the easy stuff. I get this kind of stuff pretty often. But again, I am "The Great Randini", I can do anything!

You ain't wrong brutha!

Carbide. You just have to have the right grade.

Comes with a reference temperature at time of inspection correct?

They don't tell us nuthin. Just "Here ya go. Make my parts."

Which would you rather? Chrome Molly or aluminum bronze?

Aluminum bronze. All day over chrome molly.

They think that if they can draw it, we can make it. It always looks simple on paper.

Ain't that the truth!

You don't know how bad I wish they made a put it back on tool.

Probably 90% of what I do should be ground. Once everyone found out we could hold these tolerances, they bypass the grind. The diameters on these are 1.7497 +/-.0001 by 1.125 long O.D. and 2.566 +/-.0001 by 1.125 O.D.. I would rather they were made out of heat treated 17-4. It would be much easier.

Can't you just run the machine in reverse?
