I've used an angle grinder with a flap disk to make cast iron smooth.

Wot e said.

I have a cast-iron pan, ground flat on the stove side. The food side had a
grainy texture from casting in a sand mold. Food stuck...

Angle grinder with a coarse gritty sponge sorted it -- looked a bit like a 3M
abrasive scouring pad, but much coarser. This wore at the edges, and made it
easy to get the rounded corners smooth as well. Smooth but not flat -- but food
doesn't stick anymore...
