Engenharia de Ferramental em A\u00e7o de Molde NAK80 e Blueprint de EDM<\/h2>\n

Executando a\u00e7o NAK80 de precis\u00e3o Fabrica\u00e7\u00e3o de Moldes Personalizados<\/strong><\/a> requer avan\u00e7os de corte CNC cuidadosos, perfilagem de eletrodo de cobre para EDM e polimento manual:<\/p>\n

N\u00facleo Pr\u00e9-Endurecido 40 HRC<\/p>\n

Pr\u00e9-endurecido por meio de endurecimento por precipita\u00e7\u00e3o (age-hardening) a 37\u201343 HRC. Isso elimina a distor\u00e7\u00e3o por t\u00eampera p\u00f3s-usinagem, permitindo que a Jucheng corte dimens\u00f5es de cavidade fi\u00e9is ao CAD diretamente em CNCs de 5 eixos.<\/p>\n<\/div>\n

Faiscamento EDM Sem Microporos<\/p>\n

A estrutura uniforme de liga cobre-alum\u00ednio-n\u00edquel do NAK80 responde de forma previs\u00edvel \u00e0 eros\u00e3o por fa\u00edsca no EDM de penetra\u00e7\u00e3o. Ela produz texturas foscas VDI limpas e uniformes, sem microporos ou ac\u00famulo de carbono.<\/p>\n<\/div>\n

Soldabilidade a Laser e Manuten\u00e7\u00e3o<\/p>\n

O NAK80 apresenta excelente soldabilidade. Em caso de altera\u00e7\u00f5es de engenharia (ECOs) ou desgaste da linha de parti\u00e7\u00e3o, nossos ferramenteiros depositam arame NAK80 correspondente usando micro-soldadores a laser sem causar distor\u00e7\u00e3o t\u00e9rmica local.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
