Processus d'usinage CNC pour les pi\u00e8ces complexes<\/span><\/h1>\n

Les pi\u00e8ces complexes sont les produits de traitement les plus courants dans le processus d'usinage CNC. Son itin\u00e9raire de traitement sera couvert, y compris la s\u00e9lection des m\u00e9thodes de traitement, la division de l'\u00e9tape de traitement, le processus de division, l'arrangement de la s\u00e9quence de traitement et la d\u00e9termination de l'itin\u00e9raire de traitement, etc.<\/p>\n

1. D\u00e9termination des pi\u00e8ces \u00e0 blanc<\/strong><\/span><\/p>\n

Selon la conception du processus des pi\u00e8ces, la s\u00e9lection de l'\u00e9bauche consiste \u00e0 d\u00e9terminer le type d'\u00e9bauche, la m\u00e9thode de fabrication et la taille de l'\u00e9bauche apr\u00e8s avoir d\u00e9termin\u00e9 la quantit\u00e9 r\u00e9siduelle.<\/p>\n

Le mat\u00e9riau est l'acier. Selon les exigences techniques, les pi\u00e8ces doivent \u00eatre \u00e9bavur\u00e9es, c'est-\u00e0-dire qu'elles doivent avoir un aspect propre et beau. Selon la forme structurelle des pi\u00e8ces, les dimensions globales peuvent \u00eatre choisies pour le forgeage.<\/p>\n

Il est n\u00e9cessaire de s\u00e9lectionner l'acier qui a \u00e9t\u00e9 trait\u00e9, car il a une duret\u00e9 \u00e9lev\u00e9e et est adapt\u00e9 \u00e0 la coupe.<\/p>\n

 <\/p>\n

2. d\u00e9termination du point de r\u00e9f\u00e9rence des pi\u00e8ces complexes<\/span><\/strong><\/p>\n

Lors de la s\u00e9lection des rep\u00e8res grossiers pour le traitement, la principale consid\u00e9ration est de s'assurer qu'il y a suffisamment de marge pour chaque surface d'usinage, afin que la taille et la position de la surface usin\u00e9e et de la surface non usin\u00e9e correspondent aux empreintes. Par cons\u00e9quent, l'\u00e9bauche
\nEn fonction du traitement du concave, des exigences d'usinage du trou, choisir la plaque de base pour situer le point de r\u00e9f\u00e9rence.<\/p>\n

 <\/p>\n

3. s\u00e9lection des machines<\/strong><\/span><\/p>\n

Diff\u00e9rents types de pi\u00e8ces doivent \u00eatre usin\u00e9s sur diff\u00e9rentes machines CNC, selon diff\u00e9rents processus d'usinage CNC, et les machines-outils doivent \u00eatre s\u00e9lectionn\u00e9es en fonction de la conception des pi\u00e8ces.<\/p>\n

a). Le tour CNC convient \u00e0 l'usinage de pi\u00e8ces d'arbre complexes et de la cavit\u00e9 int\u00e9rieure du moule form\u00e9e par la courbe complexe en rotation.<\/p>\n

b).\u00a0Usinage vertical CNC<\/a> sont adapt\u00e9s au traitement des bo\u00eetes, des couvercles de bo\u00eetes, des CAM plates, des formes complexes ou des cavit\u00e9s internes et externes des moules.<\/p>\n

c). Le centre d'usinage horizontal CNC convient \u00e0 l'usinage de toutes sortes de pi\u00e8ces complexes, de corps de pompe, de corps, d'enveloppe, etc. Le centre d'usinage horizontal \u00e0 coordonn\u00e9es multiples peut \u00e9galement \u00eatre utilis\u00e9 pour traiter diverses courbes complexes, des surfaces, des roues, des moules, etc.<\/p>","protected":false},"excerpt":{"rendered":"
