Fräser: Was es tut, Verwendungsmöglichkeiten, und wie man wählt

A milling cutter is a rotary cutting tool for milling machines and CNC machining centers. It removes material from a workpiece to create flat surfaces, Slots, pockets, Profile, holes, threads, and complex shapes.

For engineers, machinists, buyers, and distributors, choosing the right milling cutter is important. A suitable cutter can improve cutting stability, Oberflächenbeschaffenheit, Standzeit des Werkzeugs, and machining efficiency. Jedoch, different milling cutter types are designed for different materials and operations.

daher, this guide explains what a milling cutter does, common CNC machining uses, basic cutter types, and how to choose the right tool for different materials and applications.

What Is a Milling Cutter?

A milling cutter is a multi-edge cutting tool that rotates to remove material from a workpiece. Unlike a single-point turning tool, a milling cutter usually has several cutting edges. These edges cut the material repeatedly as the tool rotates.

Manufacturers use milling cutters for many machining tasks, including facing, Schlitzen, Seitenfräsen, Profilierung, Konturierung, Schruppen, und Abschluss. Zusätzlich, different cutter designs can support different materials, such as aluminum, Stahl, Edelstahl, Gusseisen, Graphit, and engineering plastics.

For general CNC slotting, Profilierung, und Taschenfräsen, many factories start with an Schaftfräser.

Was macht ein Fräser??

A milling cutter removes material from a workpiece during milling operations. It rotates at high speed and uses its cutting edges to cut, shape, and finish different materials.

In der CNC-Bearbeitung, a milling cutter can do many jobs. Zum Beispiel, it can create flat surfaces, straight slots, Seitenprofile, pockets, gekrümmte Oberflächen, T-Nuten, threads, and rough shapes before finishing.

The exact function depends on the cutter type. An end mill cutter is useful for slotting and profiling. A ball nose end mill is better for curved surfaces and mold cavities. A T-slot cutter creates T-shaped slots and undercuts. In der Zwischenzeit, diamond-coated end mills are often used for graphite and abrasive materials.

Common Types of Milling Cutters

This section gives a simple overview of common milling cutter types. For a more detailed classification guide, Lesen Sie unsere Fräsertypen Führung.

Different milling cutter types have different shapes and functions. daher, the best choice depends on the machining operation, Material, und Oberflächenbedarf.

Schaftfräser-Fräser

An end mill cutter is one of the most common milling cutters. It can cut from the side and the end of the tool. Aufgrund dieses Designs, it is suitable for slotting, Profilierung, Taschenfräsen, Schulterfräsen, und Konturierung.

End mill cutters come in different flute counts, Beschichtungen, Durchmesser, Flötenlängen, and tool materials. Zum Beispiel, 2 flute end mills are often used for aluminum, while 4 flute end mills are commonly used for steel.

CNC Milling Cutter

A CNC milling cutter works on CNC machining centers for accurate and repeatable cutting. These tools need stable geometry, good tool holding, and suitable coating to support consistent machining quality.

CNC milling cutters can include end mills, ball nose tools, bull nose tools, T-Nutenfräser, Scheibenfräser, Planfräser, thread milling cutters, and other carbide cutting tools. In many production environments, carbide tools are preferred because they offer better wear resistance and higher cutting stability than general HSS tools.

Kugelfräser

A ball nose end mill has a round cutting tip. This design makes it suitable for 3D contouring, gekrümmte Oberflächen, Formhohlräume, and die machining.

Mold shops often choose ball nose tools when the part requires smooth curved surfaces. Jedoch, a ball nose end mill is not the best option for sharp inside corners.

For 3D contouring and mold machining, Sehen Sie sich unsere an Kugelkopffräser.

Bull-Nase-Schaftfräser

A bull nose end mill is also called a corner radius end mill. It has a small radius on the cutting corner. This radius improves corner strength and helps reduce chipping during machining.

Infolge, bull nose end mills work well for semi-finishing, rough finishing, and machining materials such as steel and stainless steel.

For stronger corner cutting and semi-finishing, Sehen Sie sich unsere an Bull-Nase-Schaftfräser.

T-Nutenfräser

A T-slot cutter creates T-shaped slots and undercuts. These slots are common in machine tables, Vorrichtungen, Formen, and clamping systems.

Usually, the first straight slot is made with an end mill. Dann, the T-slot cutter creates the wider undercut shape. This process helps reduce tool load and improves machining stability.

For T-slot and undercut machining, Sehen Sie sich unsere an T-Nutenfräser.

Seitlicher Fräser

A side milling cutter cuts grooves, Slots, und Seitenflächen. It removes material from the side of a workpiece and is useful for wider grooves or side cutting operations.

In general machinery and mold part production, side milling cutters can improve cutting efficiency when the setup is stable.

For groove and side surface machining, Sehen Sie sich unsere an Scheibenfräser.

Diamond-Coated Milling Cutter

Diamond-coated milling cutters are used for graphite, Verbundwerkstoffe, und andere abrasive Materialien. These materials can wear normal cutting edges quickly, so tool coating becomes very important.

Diamond coating can improve wear resistance and help extend tool life in graphite machining. Jedoch, the tool should still match the machine condition, Schnittparameter, and workpiece material.

For graphite and abrasive materials, Sehen Sie sich unsere an Diamantbeschichtete Schaftfräser.

How to Choose a Milling Cutter by Material

Material is one of the first factors to check before choosing a milling cutter. A tool that works well for aluminum may not work well for stainless steel, gehärteter Stahl, or graphite.

Aluminum Applications

Aluminum is soft, but chips can stick to the cutting edge if chip removal is poor. daher, 2 Flöte bzw 3 flute end mills are often better choices.

These tools provide more flute space and help remove chips from the cutting area. Zusätzlich, sharp cutting edges and polished flutes can improve cutting stability.

For aluminum slotting and soft materials, Sehen Sie sich unsere an 2 Nutfräser.

Steel Applications

Steel needs stronger tool rigidity and stable cutting performance. Aus diesem Grund, 4 flute carbide end mills are commonly used in steel machining.

A 4 flute design provides more cutting edges and better tool strength than a 2 flute tool. Infolge, it is suitable for side milling, Profilierung, Abschluss, and general steel milling.

For steel and general CNC milling, Sehen Sie sich unsere an 4 Nutfräser.

Stainless Steel Applications

Stainless steel can generate heat and work harden during machining. daher, the cutter should have a sharp edge, geeignete Beschichtung, and stable flute design.

In vielen Fällen, coated carbide milling cutters are better choices for stainless steel. Jedoch, Kühlmittel, Steifigkeit der Maschine, Werkzeughaltung, and cutting parameters also affect the final result.

For steel and stainless steel cutting, Sehen Sie sich unsere an Hartmetall-Schaftfräser.

Graphite Applications

Graphite is abrasive, so tool wear is a major concern. In this case, diamond-coated end mills can improve wear resistance and help maintain cutting performance for longer.

Many mold shops use diamond-coated tools for graphite electrodes and abrasive material machining.

Zur Graphitbearbeitung, wählen Diamantbeschichtete Schaftfräser.

How to Choose a Milling Cutter by Operation

Besides material, the machining operation also affects cutter selection. daher, you should match the cutter type with the cutting task.

Slotting Applications

Slotting needs good chip evacuation because the cutter works inside a narrow groove. In aluminum machining, 2 Flöte bzw 3 flute tools usually work better because they provide more chip space.

When cutting steel slots, machinists can choose 2 Flöte bzw 4 flute tools based on slot depth, Kühlmittel, und Maschinensteifigkeit.

Profiling Applications

Profiling means cutting the side of a workpiece to create contours, outside edges, or side walls. End mill cutters are often suitable for this operation because they can cut from the side and the end.

For stable profiling, choose the correct flute length and avoid using a tool that is longer than necessary.

Finishing Applications

Finishing requires stable cutting and a better surface finish. daher, many machinists choose 4 Flöte bzw 6 flute end mills when chip evacuation is not a major problem.

For finishing and stable side milling, Sehen Sie sich unsere an 6 Nutfräser.
