You can see an example of its work: a multi-piece striped bowed psaltery back. It is made of quilted maple and purpleheart.
Ordinarily, it would take me a very long time to clean up all of the glue lines and get everything sanded perfectly flat and level. Additionally, with the quilted maple, I was unable to use a planer or jointer on the piece, as the knives would simply tear out the grain. (But the sander is gentle with the maple’s figure and preserves the board’s integrity.)
Now, I can just set the bowed psaltery back on the conveyor belt, and let the sander do all of the work for me within seconds, and with a much greater degree of accuracy than is possible with hand sanding.
