Neste artigo, centrar-nos-emos na introdu\u00e7\u00e3o de diferentes tipos de fresadoras e tornos CNC, bem como nas suas combina\u00e7\u00f5es. O movimento das m\u00e1quinas CNC pode ser definido pelos seus eixos, incluindo o eixo X, o eixo Y e o eixo Z. As m\u00e1quinas mais avan\u00e7adas tamb\u00e9m incluem o eixo A, o eixo B e o eixo C. Os eixos X, Y e Z representam os vectores cartesianos principais, enquanto os eixos A, B e C representam a rota\u00e7\u00e3o dos eixos. As m\u00e1quinas CNC utilizam normalmente at\u00e9 5 eixos. Segue-se uma lista de m\u00e1quinas CNC t\u00edpicas.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" src=\"http:\/\/jbsy-china.com\/wp-content\/uploads\/2023\/04\/image.png\" alt=\"What is a CNC machine?\" class=\"wp-image-24704\"\/><\/figure>\n\n\n\n<p><strong><a href=\"http:\/\/jbsy-china.com\/pt\/cnc-machining-service\/\" data-type=\"URL\" data-id=\"http:\/\/jbsy-china.com\/cnc-machining-service\/\" target=\"_blank\" rel=\"noreferrer noopener\">Torno CNC<\/a><\/strong> - Este tipo de torno funciona atrav\u00e9s da rota\u00e7\u00e3o de materiais no mandril do torno. De seguida, a ferramenta desloca-se em dois eixos para cortar componentes cil\u00edndricos. Os tornos CNC podem formar superf\u00edcies curvas, enquanto os tornos manuais s\u00e3o dif\u00edceis ou mesmo imposs\u00edveis de formar superf\u00edcies curvas. As ferramentas s\u00e3o normalmente n\u00e3o rotativas, mas se forem el\u00e9ctricas, tamb\u00e9m podem ser movidas.<\/p>\n\n\n\n<p><strong>Fresadoras CNC<\/strong> - As m\u00e1quinas de fresagem CNC s\u00e3o normalmente utilizadas para fabricar componentes planos, mas as m\u00e1quinas mais complexas t\u00eam mais graus de liberdade e podem produzir formas complexas. O material est\u00e1 estacion\u00e1rio, o eixo roda com a ferramenta e a ferramenta move-se ao longo de tr\u00eas direc\u00e7\u00f5es de eixo para cortar o material. Nalguns casos, o fuso est\u00e1 parado enquanto o material se move.<\/p>\n\n\n\n<p><strong>Perfura\u00e7\u00e3o CNC<\/strong> - Esta m\u00e1quina \u00e9 semelhante a uma fresadora CNC, mas foi especialmente concebida para cortar apenas ao longo de um eixo, ou seja, para perfurar o material apenas ao longo do eixo Z, em vez de cortar ao longo dos eixos X e Y.<\/p>\n\n\n\n<p><strong>M\u00e1quina de retifica\u00e7\u00e3o CNC<\/strong> - Esta m\u00e1quina permite que a m\u00f3 entre em contacto com o material, produzindo uma superf\u00edcie de alta qualidade.
