Abstract
A system for enhancing the surfaces of building blocks by cutting or grinding away material from the surface to be enhanced. A building block is placed on a conveyer belt which moves the block passed three rotating cutting apparatus each of which is independently powered. Each of the cutting apparatus is independently adjustable in the vertical direction and all three cutting apparatus may be adjusted simultaneously. The system may also be pivoted to allow an enhanced beveled surface to be formed on the building blocks. Also included is a water system for cooling the cutting apparatus and the building block, and an oil system for lubricating the cutting apparatus.
