Abstract

pistão e método de fazer um pistão um pistão de peça única (20) que inclui um recipiente de combustão (26) o qual é fundido em sua forma final e inclui pelo menos uma irregularidade espaçada a partir de um eixo central (a). o pistão (20) é fabricado inicialmente com um membro de coroa superior (22) e um membro de coroa inferior (24), os quais são unidos. o pistão (20) é em seguida sujeito ao mandril de maquina (54), tal como torno cnc, o qual localiza a superfície superior do pistão (32) ou uma porção do recipiente de combustão (26) e estabelece a sua localização como um plano de referência. é esse plano de referência que serve como uma localização de referencia para as operações de usinagem subsequentes do pistão (20).
