Abstract
The present invention provides a method and apparatus for supplying process liquid s for a machine tool, which are able to reduce the consumption power and power factor of the pump 21 to a large extent in comparison with prior arts while maintaining the effects of process liquid s according to prior arts. The invention is embodied so that process liquid s such as coolant or cleaning fluid is supplied to necessary points by causing the process liquid s to flow down, which is stored in a sub tank 20 installed at a suitable height in a machine tool, by a gravity action when intermittently supplying the process liquid s such as coolant or cleaning fluid to the necessary points such as a workrest 2 and a workpiece w fixed thereon; the supplied process liquid s is collected into a main tank 19 on the other hand; and the process liquid s stored in the main tank 19 is transferred into the sub tank 20 by the pump 21.
