Spindle for grinding machine

Abstract

A spindle for rotating a grinding wheel of a grinding apparatus for grinding a substrate on which a balancing mechanism is provided for balancing the grinding wheel. The balancing mechanism is disposed on a shaft portion of the spindle, adjacent to the grinding wheel. The balancing mechanism includes a flange which includes an internal cavity configured to receive balancing components movable within the internal cavity during rotation of the grinding wheel. The internal cavity is configured to be accessible to adjust one or more of the balancing components. The spindle may be self-balancing, adjustable and / or otherwise enhanced to improve use of the grinding apparatus, such as by enabling easy and convenient adjustment of balancing properties of the spindle to balance the grinding wheel so as to provide optimal grinding of the substrate, manufacturing and / or servicing (e.g., maintenance or repair) of the spindle.
