Cooling apparatus for grinding machines

Apparatus for supplying coolant to a location of contact between a workpiece and a material removing tool, comprising nozzle supporting means including at least one mobile carrier, a plurality of different coolant discharging nozzles provided on said at least one carrier, said at least one carrier being movable between a plurality of different positions at which one selected nozzle of said plurality of nozzles can be directed toward and can discharge a coolant stream against said location;

• and means for supplying coolant to said nozzles, said coolant supplying means including means for channeling coolant only to that one selected nozzle which is directed to discharge coolant upon said location.

Apparatus for supplying coolant to a location of contact between a workpiece and a material removing tool operating in a machine, said apparatus comprising nozzle supporting means including at least one mobile carrier;

• a plurality of different coolant discharging nozzles provided on said at least one carrier, said at least one carrier being movable between a plurality of different positions at which one selected nozzle of said plurality of nozzles can be directed toward and can discharge a coolant stream against said location;
• and means for supplying coolant to said nozzles,
• wherein in said machine said location is shifted during removal of material from said workpiece, further comprising means for imparting to said at least one carrier translational and rotary movements to maintain said selected nozzle directed toward said location while the location is being shifted during removal of material from said workpiece.

Apparatus for supplying coolant to a location of contact between a workpiece and a material removing tool, comprising nozzle supporting means including at least two mobile carriers;

• a respective plurality of different coolant discharging nozzles being provided on each of said at least two carriers, said carriers being rotatably movable between a plurality of different positions at which a nozzle of each said respective plurality of nozzles can be directed toward and can discharge a respective coolant stream against said location said carriers being on opposite sides of said location;
• and means for supplying coolant to said nozzles.
