Abstract: A power saw machine for cutting a work piece includes a supporting frame, a cutting blade, and an environment control arrangement which includes a cutting table base, a sliding vacuum hood, and an outlet. The cutting table base is slidably supported by the supporting frame for supporting the work piece. The sliding vacuum hood has a narrow collecting chamber with a continuous inlet for directly contacting with the work piece to omit a spatial gap between the narrow collecting chamber and the work piece, wherein during the cutting process, a cutting portion of the cutting blade is entered into the narrow collecting chamber through the continuous inlet for cutting the work piece. The outlet is provided at the sliding vacuum hood for sucking residual debris of the work piece within the narrow collecting chamber during the cutting process.

Abstract: 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.

Abstract: A rivering filtration system for a power saw machine includes a filtration tray having a filtration cavity for collecting operation fluid after the operation fluid is delivered onto the cutting blade, and a fluid collecting tray located underneath the filtration tray, wherein the fluid collecting tray has first and second cavities. The filtration tray provides a first filtration stage for filtrating the visible residual particles out from the operation fluid. The fluid collecting tray provides a second filtration stage that the operation fluid is slowly filled in the first cavity from the filtration cavity to ensure slurry residual particles in the operation fluid being deposited at the first cavity, and a third filtration stage that the operation fluid is slowly filled in the second cavity from the first cavity to ensure the slurry residual particles being filtrated out of the operation fluid.
