Abstract: An apparatus is provided which is particularly adapted for maximizing lateral stiffness of a rotating saw blade. Temperature sensors measure the temperature of a rotating plate or saw blade. A displacement probe measures the degree of lateral displacement of the rotating plate or blade. A heating means heats the rotating plate or blade, so as to control the lateral stiffness of it. The displacement means is preferably an electromagnet, while the heating means is preferably one or more induction heating coils.
