What Are Milling Cutter Types?

Milling cutter types refer to different cutter designs used for different machining tasks. Some cutters remove material quickly. Some create flat surfaces. Others machine slots, threads, 곡면, or special profiles.

CNC 가공에서, the cutter type should match the operation, 공작물 재료, 기계 강성, 표면 요구 사항. A wrong cutter type may cause poor surface finish, 진동, chip clogging, short tool life, or unstable machining.

Milling Cutter Types by Tool Structure

Milling cutters can also be classified by tool structure. This is useful for buyers who need to compare cost, 정도, replacement method, and production scale.

Solid Milling Cutters

Manufacturers make solid milling cutters from one complete tool body. Common materials include HSS and solid carbide. Machinists often choose them for precision machining, small-batch production, 금형 부품, and applications that require good rigidity.

Solid carbide cutters are especially common in CNC machining because they offer better hardness, 내마모성, and cutting stability than many general HSS tools. 하지만, the tool should still match the workpiece material, 코팅, 플루트 수, and cutting parameters.

Indexable Milling Cutters

Indexable milling cutters use a reusable cutter body with replaceable carbide inserts. When the cutting edge wears, the operator can index or replace the insert instead of replacing the whole cutter body.

Factories often use this type for face milling, 숄더 밀링, 무거운 황삭, and batch production. It can help reduce tool replacement cost in suitable applications, especially when machining larger parts or removing more material.

Brazed Milling Cutters

Brazed milling cutters use carbide tips brazed onto a steel body. Machinists often use them for general machining and some roughing applications.

Compared with solid carbide tools, brazed cutters can be more economical in some jobs. 하지만, they are not always the best choice for high-speed machining, high-heat cutting, or applications that require frequent tool replacement.

Common Milling Cutter Types and Uses

The table below shows common milling cutter types and their main uses. It is useful for buyers, engineers, and machinists who want to compare different cutter options before choosing a tool.

Main Types of Milling Cutters

엔드밀 커터

An end mill cutter is one of the most common milling cutter types. It can cut from the side and the end of the tool, so it is suitable for slotting, 프로파일링, 포켓 밀링, 컨투어링, 및 숄더 밀링.

End mills come in different flute counts, 코팅, 길이, 및 초경 등급. 예를 들어, 2 flute end mills are often used for aluminum because they provide more chip space. 대조적으로, 4 flute end mills are often used for steel because they offer better rigidity and cutting stability.

For general CNC milling, 우리의 보기 엔드밀 커터.

볼 노즈 엔드밀

A ball nose end mill has a round cutting tip. This cutter type is used for 3D contouring, 곡면, 금형 구멍, 다이 가공, 정밀한 마무리.

Compared with a flat end mill, a ball nose cutter can follow curved tool paths more smoothly. 하지만, it is not the best choice for sharp inside corners because the cutting tip is round.

For mold machining and curved surfaces, 선택하다 볼 노즈 엔드밀.

불 노즈 엔드밀

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

Bull nose end mills are useful for semi-finishing, rough finishing, and machining materials such as steel and stainless steel. They are a good choice when a sharp square corner is not required, but stronger tool corners are needed.

For semi-finishing and stronger corners, 보다 불 노즈 엔드밀.

T-슬롯 커터

A T-slot cutter machines T-shaped slots and undercuts. These slots are common in machine tables, 비품, 금형, and clamping systems.

Usually, an end mill first opens a straight slot. Then, 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, use a T 슬롯 커터.

사이드 밀링 커터

A side milling cutter cuts grooves, 슬롯, 및 측면. It removes material from the side of the workpiece and works well for wider grooves or vertical side cutting.

This cutter type is often used in general machinery, fixture parts, 금형 부품, 및 금속 가공 응용 분야. 하지만, the setup must be stable because side cutting can create higher cutting forces.

For groove and side surface machining, 보다 side milling cutter.

페이스 밀링 커터

A face milling cutter is used to machine flat surfaces. It is often used for large surfaces, machine bases, mold plates, 고정판, and metal blocks.

Compared with a small end mill, a face milling cutter can cover a wider cutting area. 그러므로, it is suitable when the workpiece needs a clean, flat, and consistent surface before the next machining step.

For large flat surface machining, 보다 페이스 밀링 커터.

스레드 밀링 커터

A thread milling cutter machines internal or external threads on CNC machines. It can be useful when the part needs accurate threads, different thread sizes, or better control than traditional tapping.

Thread milling also helps reduce the risk of tap breakage in some difficult materials. 하지만, it requires proper CNC programming and a stable machining setup.

For precision thread machining, 보다 스레드 밀링 커터.

러핑엔드밀

A roughing end mill is designed for fast material removal. It usually has a special cutting edge design that breaks chips into smaller pieces and reduces cutting pressure.

This cutter type is often used before finishing. It removes extra material quickly and prepares the part for a smoother final surface. 하지만, roughing end mills are not usually used when the final surface finish is the main requirement.

For fast stock removal before finishing, 선택하다 황삭 엔드밀.

Diamond-Coated End Mill

Diamond-coated end mills are used for graphite, CFRP, 복합재, and other abrasive materials. These materials can wear normal cutting edges quickly, so coating selection is very important.

Diamond coating can improve wear resistance and help extend tool life in graphite machining. 하지만, the tool should still match the workpiece material, 절단 매개변수, 그리고 기계상태.

For graphite and abrasive materials, 선택하다 다이아몬드 코팅 엔드밀.

How to Choose Milling Cutter Types by Operation

Different machining operations need different cutter types. 그러므로, you should choose the cutter based on the cutting task first.

Cutter Type for Slotting

End mill cutters are usually the most common choice for slotting. In aluminum machining, 에이 2 flute end mill often works well because it provides more chip space.

When cutting steel slots, machinists may choose a 2 플루트 또는 4 flute tool depending on slot depth, 냉각수, 및 기계 강성.

Cutter Type for Steel Machining

Steel needs stronger cutting edges and better tool rigidity. 이러한 이유로, 에이 4 flute end mill is often used for general steel milling, 프로파일링, 그리고 사이드 밀링.

게다가, coated carbide tools can improve heat resistance and tool life.

Cutter Type for Finishing

Finishing requires stable cutting and better surface quality. 그러므로, many machinists choose 4 플루트 또는 6 flute end mill tools when chip evacuation is not a major problem.

A higher flute count can improve surface finish, but the tool must match the machine rigidity and cutting parameters.

How to Choose Milling Cutter Types by Material

Workpiece material also affects cutter selection. A cutter type that works well for aluminum may not work well for stainless steel or graphite.

When choosing a cutter type, do not only compare price. 대신에, check the workpiece material, 절단 깊이, 공구 길이, 코팅, 플루트 수, 및 표면 마감 요구 사항.

For high-performance carbide tools, 보다 초경 엔드밀 커터.

Milling Cutter Types Selection Checklist

Before choosing a milling cutter type, check these points:

요컨대, the best milling cutter type depends on both the material and the machining operation. A suitable cutter can reduce tool wear, improve surface finish, and make CNC milling more stable.
