  • Patent number: 4414783
    Abstract: A coolant system for use with a cutter of the type having a vertically disposed rotatable cutter wheel for cutting metallurgical samples and other objects. Such a cutter has a motor-driven rotatable abrasive or metal cutting wheel or blade, and a workpiece holder which holds a specimen workpiece from which a section is to be sliced off. Either the cutter wheel or the workpiece holder is movable to bring the workpiece into engagement with the cutter wheel. The coolant system is combined with a blade guard which covers a major portion of the rotatable cutting blade for safety reasons, and the coolant system distributes a coolant fluid in an advantageous manner onto the center of the vertically disposed rotating cutting blade on both sides thereof so as to bathe the workpiece over the entire cutting area. The coolant system is primarily intended for use with a cutter of the type where the workpiece is moved into engagement with the cutter wheel during a cutting operation.
