por atrito e fa\u00edscas, esta l\u00e2mina de serra a frio utiliza dentes de corte duros, retificados com precis\u00e3o, para cortar mecanicamente a parede do tubo. Durante a rota\u00e7\u00e3o a alta velocidade e o avan\u00e7o controlado, o l\u00edquido de arrefecimento de corte lava continuamente a zona de corte para dissipar o calor instantaneamente. Toda a energia t\u00e9rmica do corte \u00e9 removida pelas limalhas, pelo que n\u00e3o ocorre qualquer zona afetada pelo calor (HAZ), oxida\u00e7\u00e3o do tubo ou deforma\u00e7\u00e3o t\u00e9rmica nas extremidades do tubo, permitindo um verdadeiro corte a frio de pe\u00e7as tubulares.
