A produ\u00e7\u00e3o de um pun\u00e7\u00e3o de precis\u00e3o come\u00e7a com um desenho.<\/p>\n\n\n\n
As dimens\u00f5es, os raios e a geometria do perfil definem como deve ser o componente acabado. O desafio consiste, ent\u00e3o, em reproduzir essa geometria com precis\u00e3o no componente real.<\/p>\n\n\n\n
Este pun\u00e7\u00e3o de precis\u00e3o KD20 \u00e9 um bom exemplo desse processo.<\/p>\n\n\n\n
A geometria cr\u00edtica do pun\u00e7\u00e3o foi conclu\u00edda por Retifica\u00e7\u00e3o de perfis (PG)<\/strong>, permitindo que o perfil pretendido seja definido diretamente a partir das especifica\u00e7\u00f5es do desenho.<\/p>\n\n\n\n

Retifica\u00e7\u00e3o de perfis para pun\u00e7\u00f5es de precis\u00e3o<\/h2>\n\n\n\n
A retifica\u00e7\u00e3o de perfis \u00e9 particularmente \u00fatil para componentes de estampagem de precis\u00e3o, em que a pr\u00f3pria geometria do perfil \u00e9 fundamental.<\/p>\n\n\n\n
No caso deste pun\u00e7\u00e3o, o objetivo n\u00e3o se limitou a obter a forma geral. O perfil, as transi\u00e7\u00f5es e os requisitos dimensionais tiveram de ser controlados durante o processo de retifica\u00e7\u00e3o.<\/p>\n\n\n\n
O resultado apresenta um perfil claramente definido e um acabamento superficial controlado.<\/p>\n\n\n\n
Do desenho ao pun\u00e7\u00e3o acabado<\/h2>\n\n\n\n
O processo de fabrico come\u00e7a com a geometria definida no desenho.<\/p>\n\n\n\n
O perfil cr\u00edtico \u00e9 ent\u00e3o reproduzido atrav\u00e9s de um retificado de perfil controlado, antes de o componente acabado ser inspecionado de acordo com as especifica\u00e7\u00f5es exigidas.<\/p>\n\n\n\n
Este processo pode revelar-se especialmente \u00fatil na estampagem de componentes de ferramentas, em que a precis\u00e3o do perfil e a repetibilidade s\u00e3o fundamentais.<\/p>\n\n\n\n
Um desenho pode parecer simples no papel.<\/p>\n\n\n\n
\u00c9 ao transformar essa geometria num componente f\u00edsico coerente que come\u00e7a o fabrico de precis\u00e3o.<\/p>\n\n\n\n

Porqu\u00ea o retificado de perfis?<\/h2>\n\n\n\n
Os diferentes processos de maquinagem t\u00eam diferentes pontos fortes.<\/p>\n\n\n\n
No caso de geometrias de pun\u00e7\u00e3o adequadas, a retifica\u00e7\u00e3o de perfis permite controlar diretamente o perfil pretendido, ao mesmo tempo que proporciona um acabamento superficial fino na pe\u00e7a acabada.<\/p>\n\n\n\n
O processo de fabrico adequado depende da geometria, do material, da toler\u00e2ncia e dos requisitos funcionais de cada componente.<\/p>\n\n\n\n
Para este pun\u00e7\u00e3o KD20, recorremos ao retificado de perfis para obter a geometria e o acabamento exigidos.<\/p>\n\n\n\n

Dependendo do modelo, um pun\u00e7\u00e3o de precis\u00e3o pode incluir:<\/p>\n\n\n\n
Carboneto ou outros materiais resistentes ao desgaste<\/li>\n<\/ul>\n\n\n\n
\u00c9 importante controlar estas caracter\u00edsticas de forma consistente para garantir o ajuste e o funcionamento finais do componente da ferramenta.<\/p>\n\n\n\n
Na Hepha Precision, coordenamos os processos de fabrico de acordo com o desenho, o material e os requisitos t\u00e9cnicos, incluindo retifica\u00e7\u00e3o de perfis, electroeros\u00e3o por fio, electroeros\u00e3o por penetra\u00e7\u00e3o e outros processos de precis\u00e3o, sempre que necess\u00e1rio.<\/p>\n\n\n\n

From Drawing to Reality A precision punch starts with a drawing. Dimensions, radii and profile geometry define what the finished component needs to be.
