Abstract

------10/11/2020------(OCR) A sheet metal cutting device for materials such as wood substitutes, fiber cement, calcium silicate board, plywood, and gypsum. It consists of two main parts: the first part is the cutting assembly, including the base and the cutting blade; and the second part is the holding arm and fastening device. This invention has a special feature: the end of the cutting blade base has at least one groove and/or a cut, drill, or protrusion in various shapes such as semi-ellipses, semi-circles, curves, geometric shapes, or polygons. This sheet metal cutting device has a mechanism to guide the cutting line during operation, making it easy and convenient for the user to determine and check the cutting line. The operation is fast, safe, and the resulting cuts are precise, neat, and aesthetically pleasing. The process is convenient, does not generate dust that harms the environment or endangers the user, reduces the risk of accidents, and significantly improves safety. The cuts are clean and beautiful, without cracking, chipping, or breaking. ------------ Page 1 of 1. Summary of the Invention: A sheet metal cutting device for materials such as wood substitutes, fiber cement, calcium silicate board, plywood, and gypsum. This invention describes a cutting tool for calcium silicate board, plywood, and gypsum board. It consists of two main parts: the cutting assembly, which includes the base and blade, and the support arm/fastening device. A unique feature of this invention is the design of the cutting blade base, which incorporates at least one groove and/or cuts, holes, or protrusions in various shapes such as semi-ellipses, semicircles, curves, geometric shapes, or polygons. This sheet metal cutter has a mechanism that guides the cutting line, making it easy and convenient for the user to determine and check the cut alignment. The process is fast, safe, and produces precise, neat, and aesthetically pleasing cuts. It minimizes dust dispersion, reducing environmental impact and user hazards, and significantly improving safety. The cuts are clean, beautiful, and prevent chipping or breakage.
