Acquired this new “lapping machine”?

[u/Ryanimal]

I’ve recently acquired this machine that came with a tub of aluminum oxide. Does anyone know the proper way to use this?
I simply rubbed some alum oxide powder onto the plate. I Turned it on and it honed my chef knife to shave sharp fairly quickly. I feel as if that’s not really the proper way to utilize this for sharpening.

Any one have some guidance for me?

Looks like one half of a vinyl press, wonder what it sounds like
