<p>Improved saw guide block and fluid for a multiple blade saw assembly. Individual guide blocks are disposed between adjacent saw blades, which blades are mounted on a common drive shaft and axially spaced. Each of the guide blocks has a pair of oppositely-directed block pads that create a magnetically-padded bearing surface. Each block pad includes magnetic portions and non magnetic portions. Each non magnetic portion has fluid delivery ports to allow the transport of ferromagnetic, lubricant, coolant, coating fluid to the magnetically-padded bearing surfaces. The magnetic portion forms a magnetic field of attraction in its vicinity for capture and adherence of ferromagnetic particles within the fluid, whereby a magnetic coating on the guide block bearings surfaces is continuously regenerated during operation of the saw assembly.</p> |
