| 摘要 |
An apparatus and method for processing and cutting structural concrete is disclosed in which the apparatus includes a first, larger cutting blade and at least one smaller cutting/finishing blade positioned adjacent to the larger cutting blade. The smaller blade have a beveled or concave cutting surface so that as the larger cutting blade forms cuts into the concrete, the smaller cutting/finishing blade rounds or bevels the edges of the cut. The rounded or beveled edges have a greater surface are and, therefore, additional strength to prevent chipping or cracking along the cuts. In the preferred embodiment, a smaller blade is positioned adjacent to each side of the larger blade to round or bevel both edges of the cut as the cut is formed by the larger blade. In accordance with one aspect of the invention, the above described apparatus can be used on previously made cuts in concrete to round or bevel the edges and avoid breakage or chipping.
