Abstract

PROCESSO PARA A PRODUÇçO DE CONTORNOS REBAIXADOS, COM ROTAÇçO SIMÉTRICA. A presente invenção refere-se a um processo para a produção de contornos rebaixados, em essência, com rotação simétrica em peças a serem trabalhadas (13) fabricadas, por exemplo, por meio de forja ou fundição, que apresentam, pelo menos, uma área parcial a ser remodelada, com um contorno inicial, em essência, simétrico. A peça a ser trabalhada (13) é fixada em sua extremidade, a não ser remodelada, em uma recepção (II), e nessa recepção (11) com sua área parcial (14) a ser remodelada é colocada através de avanço em uma ferramenta (12). A ferramenta (12), nesse caso, gira com velocidade constante ou variável em relação à área parcial (14) a ser remodelada da peça a ser trabalhada (13). Sob pressão axial, dessa forma, é produzido um contorno rebaixado na área parcial (14) da peça a ser trabalhada (13) por meio de remodelação sem levantamento de aparas.
