Fraise de précision,Outils de coupe pour l’usinage CNC de chaque matériau
Fraises are rotary cutting tools used on milling machines and CNC machining centers to remove material and create flat surfaces, machines à sous, poches, profils, fils de discussion, et contours complexes.
Their application depends on the machining operation, matériau de la pièce à usiner, fonctionnalité requise, et exigence de surface. This guide explains common milling cutter applications and the cutter families that suit different CNC milling operations.
À quoi servent les fraises?
Milling cutters remove and shape material in operations such as facing, rainurage, profilage, fraisage de poche, 3Contournage en D, ébauche, finition, and thread milling. Donc, the suitable cutter depends mainly on the feature being machined and the required cutting operation.
For basic cutter definitions, voir notre guide de fraise. For a broader classification of cutter families, voir types de fraises.
Which Milling Cutter Fits Each Application?
| Application | Typical Cutter | Utilisation typique |
|---|---|---|
| Parement | Face milling cutter or end mill | Flat and reference surfaces |
| Slotting and Grooving | End mill or T-slot cutter | Machines à sous, keyways and T-slots |
| Profiling and Pocketing | Fraise en bout | Contours, shoulders and pockets |
| 3D Contournage | Fraise à bout sphérique | Cavités de moule et surfaces courbes |
| Roughing and Finishing | Fraise d'ébauche, end mill or radius tool | Stock removal and finishing |
| Thread Milling | Fraise à fileter | Filetages internes et externes |
Common Milling Cutter Applications
Faire face à des surfaces planes
Facing removes material from the top of a workpiece to create a flat surface. Machinists commonly use this operation on mold bases, pièces de machines, plaques de fixation, blocs, and other components that require a flat reference surface.
Machinists commonly use a face milling cutter for larger flat areas, while end mills can perform facing on smaller parts or where the setup requires more flexibility.
Rainurage et fraisage de rainures
Milling cutters produce straight slots, rainures de clavette, rainures, Fentes en T, and similar internal features.
End mills commonly machine straight slots. For a T-shaped slot, machinists normally open the straight slot first and then use a T-slot cutter to machine the undercut section.
Profilage, Side Milling and Pocketing
Profiling and side milling remove material along the side of a workpiece to create contours, épaules, murs, and outside edges. Pocket milling removes material inside a defined area of the part.
An end mill cutter works well for these operations because it can machine side surfaces as well as end-cutting features. Donc, the exact geometry and size should match the profile, profondeur de poche, matériel, et configuration de la machine.
3D Contournage et usinage de moules
Milling cutters also machine curved surfaces, cavités de moule, and complex 3D contours. Machinists commonly select ball nose end mills for these applications because the rounded cutting end can follow curved tool paths.
Typical applications include mold and die machining, électrodes de graphite, profils courbes, and other components that require continuous 3D surfaces.
Roughing and Finishing
Roughing end mills can remove material efficiently, while machinists may choose standard end mills or radius tools for semi-finishing and finishing depending on the feature, matériau de la pièce à usiner, rigidité de la machine, et finition de surface requise.
Thread Milling and Special Features
Milling cutters can also machine specialized features such as internal or external threads, chanfreins, and selected undercut profiles when the cutter geometry matches the required feature. Thread milling cutters machine thread features specifically, while other special features require suitable cutter geometries based on the part shape and machining requirement.
What Affects Milling Cutter Selection?
Milling cutter selection depends on more than the workpiece material. The machining operation, dimensions de la fraise, configuration de la machine, finition de surface requise, and production conditions can all influence the suitable cutter.
Workpiece material is still important because different materials may require different cutting geometry, matériau de l'outil, préparation des bords, ou revêtement. Cependant, no single cutter or coating suits every job with the same material.
| Facteur de sélection | What to Consider |
|---|---|
| Opération d'usinage | Parement, rainurage, profilage, ébauche, finishing or another feature |
| Matériau de la pièce | Acier, acier inoxydable, aluminium, fonte, graphite or other materials |
| Tool and Setup | Cutter dimensions, atteindre, tool holding and machine rigidity |
| Exigence de surface | Ebauche, semi-finishing or finishing |
| Special Requirements | Dessin, non-standard geometry or application-specific features |
Liste de contrôle de sélection de la fraise
Before selecting a cutter for a milling application, confirm the main machining requirements first.
| Vérifier | Que confirmer |
|---|---|
| Pièce à usiner | Material being machined |
| Primary Operation | Parement, rainurage, profilage, ébauche, finishing or another feature |
| Caractéristique de la pièce | Surface, fente, poche, contour, thread or special profile |
| Configuration de la machine | Rigidité des machines, holder and available tool reach |
| Required Finish Stage | Ebauche, semi-finishing or final finishing |
| Tool Information | Existing tool model, dessin, or key dimensions, si disponible |
These details provide a better basis for cutter selection than choosing only by cutter name or price.
FAQ About Milling Cutter Uses
What are milling cutters mainly used for?
Milling cutters are mainly used for facing, rainurage, profilage, fraisage de poche, 3Contournage en D, ébauche, finition, and thread milling on milling machines and CNC machining centers.
Quelle fraise est utilisée pour les surfaces planes?
Machinists commonly use face milling cutters for larger flat surfaces. End mills can also machine smaller flat areas when the part size or machine setup makes them more practical.
Which milling cutter is used for slots and grooves?
End mills commonly machine straight slots and grooves. T-slots and other undercut features require a cutter geometry designed for the required slot shape.
Can one milling cutter be used for every machining operation?
Non. Different machining operations and part features often require different cutter geometries. Matériau de la pièce, configuration de la machine, and finish requirements further affect the final selection.
