ABSTRACT:
A saw guide system having gas lubricated bearing surfaces and liquid contact cooling of the saw blade is described. The gas lubricated bearing surfaces enclose a liquid contact coolant chamber providing a gas seal confining the liquid coolants. The use of regulated gas lubrication greatly reduces friction between the saw blade and saw guide while providing powerful centering forces which hold the saw blade precisely in position. The use of gas sealing allows the liquid coolants to be recirculated in a closed loop piping system, thus eliminating discharge to the environment while providing increased contact cooling of the saw blades.
