Ball clamped by core shaft which is positioned by thimble rotates around horizontal core shaft and the speed is steplessly controlled. Lap table above ball make eccentric orbit rotation around vertical shaft and speed is steplessly controlled. You can realize seat ring and ball grinding by replacing lapping table with seat ring with specil fixture.
What lapping does is makes the valves seat like new again. when the valve is closed and theres not a perfect seal you loose compression.
