Dans la fabrication de moules de pr\u00e9cision, il est tr\u00e8s important d'obtenir un parall\u00e9lisme parfait sur les inserts de moules. M\u00eame un \u00e9cart mineur dans le parall\u00e9lisme des inserts de moule peut entra\u00eener une usure irr\u00e9guli\u00e8re, des \u00e9clats, une qualit\u00e9 instable des pi\u00e8ces et une r\u00e9duction de la dur\u00e9e de vie de l'outil. Pour \u00eatre juste, le parall\u00e9lisme et la pr\u00e9cision dimensionnelle sont tout aussi importants.<\/p>\n\n\n\n

C'est pourquoi nous expliquerons comment obtenir le parall\u00e9lisme sur les inserts de moules<\/strong>\u00a0par une s\u00e9lection appropri\u00e9e des processus, en mettant l'accent sur Meulage PG pour les inserts de moules dans cet article<\/strong>.<\/p>\n\n\n\n

Pourquoi le parall\u00e9lisme sur les inserts de moules est essentiel<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

D'apr\u00e8s l'exp\u00e9rience pass\u00e9e, de nombreux moules \u00e9chouent non seulement parce que les dimensions sont hors tol\u00e9rance, mais aussi parce que contr\u00f4le du parall\u00e9lisme dans la fabrication des moules<\/strong>\u00a0a \u00e9t\u00e9 n\u00e9glig\u00e9e.<\/p>\n\n\n\n

Causes courantes des erreurs de parall\u00e9lisme des inserts de moule<\/strong><\/h2>\n\n\n\n
