Yes and No.
is that clear enough? My FIL has something like that where he works. So after about the 5th or 6th time of me sharpening by hand I send the chain with him to work and he will sharpen it for me. I watched him set it up once. I looked to be a pain in the neck but it does give a nice sharp edge.
I sure you will get some that will say the only way to sharpen is with a hand file and practice. But, I feel that if you get a good sharp chain, it don't matter how you got it sharp (though with that tool you will remove more metal every time you sharpen than with a good file).
Just MHO.
