The invention relates to a "cooling system", which comprises a variable pump and a gear pump, wherein the gear pump directly draws the liquid house oil inside the fuel tank to the cooler for wood, and the cooled hydraulic oil is sent back to the inside of the fuel tank, and can be changed. The pump draws the hydraulic oil from the fuel tank to the oil pressure block to provide the machine tool for work, and the hydraulic oil after the work machine is returned to the inside of the fuel tank. Through the gear pump, the hydraulic oil inside the fuel tank is taken to the cooler, and the hydraulic oil in the oil tank portion is surely maintained at the allowable temperature through continuous circulation, so as to meet the requirements of the thief user, the machine tool can maintain excellent precision and improve.
