The system of rotating disks with cutting knives pairs with angular edges formed by the cutting knives pairs with angular tips (1), with sharp angular shapes (1.1) on their ends, four holes equally spaced (1.2) for fixation of the knives on the disk and format of double trapeze (1.3), whose active part is positioned on the perimeter of the two ends, which form an acute angle, making a continuous cutting surface, for which the system configuration.The cutting knives pairs with angular tips (1) are installed on the rotary disk (2) which is provided with ribs (2).1), which also have the function to do the collection of sugar cane at the time of execution of the court, bas relief (2.2) for the support of the cutting knives, protrusions on the lower part of the disk (2).3), and who also has a pin guide (2.4) and hexagonal hole (2).5), responsible for the precise and secure the knives on the disc, together with the supports fasteners (3), which are the settlement of facasno disk, being fitted with two holes (3).1) coincident with the holes of the knives, thereby allowing a good fixation through the pin guide, which passes through the hole of the knife and the support holder, and also for the application of the bolt (4),Through all the components to achieve the hexagon nut with flange (5) that uses the flat hexagonal (2.5) for blocking the system.sistema de discos rotativos com facas de corte duplas com pontas angulares, composto pelas facas de corte duplas com pontas angulares (1), com formas angulares cortantes (1.1) em suas extremidades, quatro furos equidistantes (1.2) para fixação das facas no disco e formato de duplo trapézio (1.3), cuja parte ativa está posicionada no perímetro das duas extremidades, que formam um ângulo agudo, tornando uma superfície de corte contínua, sendo que, para a configuração do sistema, as facas de corte duplas com pontas angulares (1) são instaladas em disco rotativo (2) que é dotado de nervuras de reforço (2.1) que também possuem a função
