Abstract
Provided is a liquid circulation system including: a shield that covers a boring area of a workpiece in which a hole is bored with a tip of a bit attached to a boring device; a liquid container that holds a liquid; a liquid feeder that forcibly feeds the liquid held in the liquid container to the tip; and a liquid collector that forcibly collects a liquid suspension from an area shielded by the shield and returns the liquid suspension to the liquid container. The liquid circulation system is able to ensure liquid circulation while reliably preventing backflow of the liquid suspension.
