摘要 |
There is provided a method or cutting or drilling a brittle workpiece including stone such as marble and granite, brick, concrete and asphalt, using a frame gang saw. There are provided a workpiece cut by a frame gang saw that includes one or a plurality of blades having multiple cutting tips or that includes a blade without including a cutting tip; a method of cutting the workpiece by using a frame gang saw; and a product provided by the cutting method. The workpiece is provided to include one or more grooves into which at least a portion of at least one cutting tip among the multiple cutting tips or at least a portion of the blade without a cutting tip is inserted and which is formed in a surface thereof. Here, an initial cutting time on a workpiece may be shortened to greatly improve productivity and the quality of a product and a lifespan of a frame gang saw blade may be improved by significantly decreasing deflection in the blade. |
