A cutting machine includes a motor assembly, a cutting blade powered by the motor assembly for cutting a work piece, and a cooling arrangement which includes a fluid nozzle unit for delivering cooling fluid onto a cutting edge portion of the cutting blade to ensure the cooling fluid to adhere on the cutting blade by means of adhesion and cohesion of the cooling fluid so as to cool the cutting blade during the cutting operation and to combine the cooling fluid with residual particles of the work piece after the work piece is cut. Therefore, no excessive cooling fluid is stayed on the cutting blade to minimize the formation of dust, and misting of the cooling fluid during the cutting operation.
