method for cutting a rock using an alternating vertical saw having flat blades with cutting points and method for cutting a stone using an alternating vertical saw with flat blades without cutting points

摘要

A method for cutting a stone using an alternating vertical saw having flat cutting blades and a method for cutting a stone using an alternating vertical saw having flat cutting blades The invention relates to a method for cutting or drill a brittle workpiece that includes a stone such as marble and granite, brick, concrete and asphalt using a vertical multiple saw. there is provided a workpiece cut by a vertical multiple saw that includes one or a plurality of blades having multiple cutting tips or including a blade without including a cutting tip; a method for cutting the workpiece by using a vertical multiple saw; and a product provided by the cutting method. the workpiece is provided to include one or more grooves within which at least a portion of at least one cutting tip between the multiple cutting tips or at least a portion of the blade without a cutting tip is inserted and which are formed on its surface. Here, an initial cutting time of a workpiece can be shortened to greatly improve the productivity and quality of a product and a service life of the vertical multi-saw blade can be improved by significantly reducing blade deflection.
