Abstract
A tire grinding machine includes a frame having a plurality of vertically extending posts. A chuck assembly is associated with the frame and adapted to receive and rotate a tire. A grinding assembly is associated with the frame and is movable with respect to the frame. The grinding assembly has at least one grinding element adapted to contact and remove material from the tire when rotated by the chuck assembly. A counterbalance assembly which has a cable with one end connected to a counterbalance weight and an opposite end connected to the grinding assembly is included. A block assembly may be coupled to the grinding assembly to allow pivotable movement thereof. A calibration adapter may be used to ensure proper positioning of the grinding elements, wherein a level adjuster may be used for this purpose.
