This is 1040 high carbon wear plate. They are guide rails for a steel rolling mill.



First I square up the hardened flame cut sides as far down as I can go without hitting vise jaws.

Then fly cut top surface with 4" face mill which did not work so well. Started picking up a chatter and had to slow down speeds and feeds too much. Decided to go with a 2" face mill that worked bitchen'. Got a real good chip and a great finish. The plate was too hard for a big cutter. Too much contact area.

Plates had a big 45 deg chamfer along the long sides which I kellered with the tool is used in the first op then matched the ends to the first op cut.

Palletized and DONE!!!

Coolant with inserted carbide tools on steel?

Coolant on or off on steels depends on surface footage. Generally above 400 sfm coolant off!

Hmm. I've never used a wet insert for steel due to thermal shock.

Inserts won't get thermal shocked if your not running fast...we generally use between 400-500sfm as the point where coolant gets turned off on steels.

I guess I don't know slow in machining. :)

That's a good thing!!! haha

Now if you want to see fast on tough material, check out turning Inco 718 with ceramic. I have a customer running about 1300 sfm on 718!!! It's awesome. I was at a Sandvik seminar recently and they have run ceramic up to 3000 sfm on 718!

When you are doing it right, the heat goes with the chip.

Exactly...but when using ceramic on inco at over 1k sfm EVERYTHING is glowing bright orange!

Ceramics don't survive interrupted cuts so they are only plausable in a lathe, so it don't apply here in this thread. :)

We just milled with ceramic button inserts at the Sandvik seminar and they do survive. Ceramics are progressing, but admittedly there application window is very small.

I could go on all day about this stuff, it's fun.

Time to stop the thread hijacking.
