ABSTRACT:
In a cutting machine (1) comprising cutting heads (5) rotatably supported on a universally swivellable cutting arm (2) and having arranged therein a gearing stage (7), supply of water is effected via the outer front disc (8) of the cutting head and the water flows via passages provided within the interior of the main body (15) of the cutting head to nozzles provided at the circumference thereof. The water supply flows via an essentially axial bore (12) into a cavity of the main body (15) of the cutting head and is passed from this cavity via passages (21, 22, 23) to the nozzles (FIGS. 1,2).
