High Speed Machining - 718 Inconel

Most people cut inconel at an SFM of about 50. This video shows that it can be cut at 4,000. With the right programming, tooling, tool holder and a fast ridgid machine. High speed machining can transform U.S. Manufacturing.

Make sure you have a premium holder or it won't work. This was Big Plus from Big Kaiser. It has both face and taper contact. The holder is the easiest thing you can change to get more out of your machine. They are expensive and worth every penny.

is this Dale Mickelsons work?

[LoDown1989]

Yes it is

i hate when we have orders with inconel

stainless its not that bed but inconel its nightmare

[LoDown1989]

You must be doing it wrong. You have to have everything just right - the tool holder, tool and a very rigid, fast machine. Check if your machine has a big plus spindle, if so, you should use a big plus tool holder because it holds taper and face contact. You need a lot of ridgity in the holder to handle the vibration becuase you use very high speeds and basically melt the metal in the cut. If you do it right, it's like cutting aluminum - not a nightmare.

okay thank explain,,,

i see the air blower is good enough cooler

[crazyj82]

@bestamerica With ceramic inserts, the thermal shock of any coolant would make the inserts explode.

too fast-too hot.

Has anyone tried Volumill ????

[bigbingham]

Go through tips like cheese.

It's also an Okuma machine- the rigidity is insane!

Inconel , isn"t it the metal used to make turbine blades ???

[jetpower06]

Hi there... I want to cut turbine wheels out of solid 718 soon. The problem is, that the milling tools are very small, typically less than 3mm outside dia. No chance to go in with inserts here. The machine has a high end spindle with up to 40'000rpm but very few torque. Any suggestions?
