Hard to Pick Out Suitable End Mills<\/a>? These Basics May Help<\/strong><\/h2>

The main cutting edge of the end mill is a cylindrical surface, and the cutting edge on the end face is a sub-blade. When the end mill without the center edge is working, it cannot make a feed motion along the axial direction of the milling cutter. End mills are currently widely used in various sectors such as automobile manufacturing, logistics, molds, machinery, etc., and because of the increasing use of various aspects, the application requirements are also increasing. Therefore, various problems that are common in the use of end mill applications are summarized and answered.<\/p>

[Q] Comment rectifier le \u00d812 des deux dents de la fraise en bout ?<\/p>

[Answer] First, the sand wheel should be ground, the edge of the grinding is a little angled, the milling cutter, the blade should pay attention, the outside should be higher than the inside… The slope inside should not be too oblique, probably just like this, this still has to grind more Practice only.<\/p>

[Q] Qu'est-ce qu'une fraise en bout et qu'est-ce qu'une fraise \u00e0 disque ? Quelle est la diff\u00e9rence?<\/p>

[R\u00e9ponse] Les fraises en bout sont g\u00e9n\u00e9ralement utilis\u00e9es pour le fraisage des faces d'extr\u00e9mit\u00e9, plut\u00f4t que les fraises \u00e0 rainurer pour le fraisage des fentes. La fraise \u00e0 disque est principalement utilis\u00e9e pour le fraisage de grandes faces d'extr\u00e9mit\u00e9, car le fraisage droit de la fraise \u00e0 disque est g\u00e9n\u00e9ralement grand, la face d'extr\u00e9mit\u00e9 de fraisage est plus rapide pour le fraisage et la fraise \u00e0 lame de scie est g\u00e9n\u00e9ralement utilis\u00e9e pour le fraisage.<\/p>

[Q] Why can’t the end mill cut vertically?<\/p>

[R\u00e9ponse] Lorsque la fraise en bout tourne, le milieu du bord inf\u00e9rieur est relativement statique. Il n'a pas d'usinabilit\u00e9 ni d'enl\u00e8vement de copeaux, il ne peut donc pas \u00eatre coup\u00e9 verticalement.<\/p>

[Q] How is the feed rate of the Fraise en bout<\/a> determined?<\/p>

[R\u00e9ponse] La s\u00e9lection de la quantit\u00e9 de coupe doit \u00eatre consid\u00e9r\u00e9e avec des facteurs tels que l'outil, la pi\u00e8ce \u00e0 usiner et la machine-outil. L'ar\u00eate de coupe principale de la fraise en bout est l'ar\u00eate p\u00e9riph\u00e9rique. L'avance par dent est g\u00e9n\u00e9ralement d'environ 0,1 lors de la finition. La quantit\u00e9 est g\u00e9n\u00e9ralement choisie entre 0,25 et 0,3 mm. Plus pr\u00e9cis\u00e9ment, il doit \u00eatre adapt\u00e9 aux param\u00e8tres de coupe tels que la vitesse de coupe, la profondeur de coupe axiale et la profondeur de coupe radiale.<\/p>

[Q] Quelle est la diff\u00e9rence entre la fraise en bout et la fraise en bout \u00e0 billes et son principe de s\u00e9lection\u00a0?<\/p>

[R\u00e9ponse] Fraises en bout et fraises en bout sph\u00e9rique, l'une est la t\u00eate sph\u00e9rique, l'autre est le fond plat, la fraise en bout est principalement destin\u00e9e \u00e0 l'usinage conventionnel et la fraise en bout sph\u00e9rique peut \u00eatre utilis\u00e9e pour le fraisage de la surface.<\/p>

[Q] Quelle est la diff\u00e9rence entre le collet pour la fraise en bout et le collet pour le taraud\u00a0? Devez-vous utiliser la poign\u00e9e de l'entreprise lorsque vous appuyez sur\u00a0?<\/p>

[R\u00e9ponse] Bien que la pince pour maintenir la fraise en bout \u00e0 queue droite puisse \u00eatre utilis\u00e9e pour maintenir le taraud pour le taraudage rigide, l'effet n'est pas bon, g\u00e9n\u00e9ralement le taraud de petit diam\u00e8tre ne pose aucun probl\u00e8me\u00a0; la pince ER pour le taraud est dot\u00e9e d'une rainure carr\u00e9e C'est-\u00e0-dire que la fonction de limite \u00e0 queue plate de la poign\u00e9e du taraud est d\u00e9sormais disponible chez les fabricants d'outils g\u00e9n\u00e9raux.<\/p>

[Q] What is the difference between a reamer and an end mill?<\/p>

[Answer] The reamer is a straight edge and the end mill is a spiral edge. The milling cutter has a bottom edge and the reamer does not! The reamer is used to finish the hole, while the milling cutter can be milled, washed, and side washed! Use is different!<\/p>

[Q] Comment la vitesse d'alimentation de la fraise en bout est-elle d\u00e9termin\u00e9e\u00a0?<\/p>

[R\u00e9ponse] La s\u00e9lection de la quantit\u00e9 de coupe doit \u00eatre consid\u00e9r\u00e9e avec des facteurs tels que l'outil, la pi\u00e8ce \u00e0 usiner et la machine-outil. L'ar\u00eate de coupe principale de la fraise en bout est l'ar\u00eate p\u00e9riph\u00e9rique. L'avance par dent est g\u00e9n\u00e9ralement d'environ 0,1 lors de la finition. La quantit\u00e9 est g\u00e9n\u00e9ralement choisie entre 0,25 et 0,3 mm. Plus pr\u00e9cis\u00e9ment, il doit \u00eatre adapt\u00e9 aux param\u00e8tres de coupe tels que la vitesse de coupe, la profondeur de coupe axiale et la profondeur de coupe radiale.<\/p>

[Q] What are the steps for milling the end mill?<\/p>

[Answer] First install the end mill, then move the end mill to the top of the workpiece to be milled, gently lick the upper surface of the workpiece with the end teeth of the end mill, and then lift the dial of the milling machine Zero; then move the end mill to the side of the workpiece, lower the end mill to the side of the workpiece, then gently lick the side of the workpiece with the side of the cutter, and set the handle dial in the corresponding direction to zero, then Start milling the steps. The depth of the knife is determined according to the size of the machining allowance, the strength of the material, and the size of the milling cutter. After eating from at least one knife, it is completed by dividing into several knives.<\/p>

[Q] What is the difference between an end mill and a keyway cutter?<\/p>

[Answer] The main difference between the end mill and the keyway cutter is that the end mill is used to machine flat or cylindrical surfaces, so its outer diameter is relatively loose, and the keyway cutter is used to machine the keyway. The outer diameter dimension directly affects the mating quality of the keyway and the key, so the tolerance is stricter; in addition, the keyway milling cutter has only two blade belts for machining holes, and the end mill has more than two blade belts. The end face of the end mill has a center hole, and the end face of the keyway cutter has no center hole. Therefore, the end mill is not able to feed directly down, deep down, and the center hole will withstand. The keyway cutter can be fed directly down. In addition, the keyway milling cutter, as the name implies, is used to mill the keyway, so the dimensional accuracy of the outer diameter is very high, and generally can reach an accuracy of about 0.01 mm.<\/p><\/div>","protected":false},"excerpt":{"rendered":"
