Making some forensic test machine equipment components this past week.  

These are called a "Deep Dish".

It is part of a grinding machine that grinds up and processes tough samples.  I know......"define tough sample".  Sorry, I'm a machinist, not a scientist. 

In any event, these are made from aluminum and have a ceramic insert epoxied in place to handle the grinding.

Blanks are 6061 aluminum, 6.5" Diameter x 2.375" lg. 

These are made complete in our 2014 Haas ST20 Cnc Lathe.




Here you can see the part chucked in the machine.

1st operation is complete.

Face to clean, Finish turn OD to 6.310", and drill .187" x .5" deep.










With the 1st handling done on all the pieces, it is time to set up the 2nd operation.


Here's a piece ready to be machined on the 2nd side.  We hold the finished turned OD from the 1st op in bored soft jaws.




The inserted drill you see there in the turret is .937" diameter, and is about to make short work of drilling, and roughing out the 4.770" dia. x 1.940" deep bore......in very short order!





Here you can see the finished part as it awaits to be unloaded from the machine.




Here's a close up of the finished part.





Here you have a "Before" and "After" picture.
