Abstract:
The present invention relates to a method for cutting or drilling a brittle workpiece including stones such as marble and granite, brick, concrete and asphalt, using a frame gang saw, and has as its objective a reduction in the initial cutting time of the workpiece, so that productivity may be markedly enhanced, and also to minimize deformation of the blade so that product quality and the lifetime of the frame gang saw blade may be enhanced. The key points of the invention are a workpiece for a frame gang saw wherein the workpiece is cut by a frame gang saw comprising one or more blades furnished with a plurality of cutting tips or a blade not furnished with a cutting tip, and on the workpiece are formed one or multiple grooves into at least a part of at least one cutting tip out of the cutting tips or at least a part of the blade not furnished with a cutting tip is inserted; a method for cutting the workpiece by using a frame gang saw; and a product that has been cut by the cutting method. According to the invention, not only can productivity be markedly enhanced but also the deformation of the blade can be minimized so that product quality and the lifetime of the frame gang saw are enhanced by providing a workpiece with grooves formed thereon.
