This is the business end of the $5,000 Amermac machine that actually does the tire truing. It features two electric motors. One powers the drive that slowly spins the vehicle's wheel, while the other operates the blade. As the machine operates, an onboard sharpening stone sharpens the blade, and this ensures a smooth, even cut to the tread.
