フライスカッターの種類: 一般的な種類と選び方

Milling cutter types vary by shape, cutting edge design, フルート数, コーティング, and machining purpose. Each cutter type is designed for a different CNC milling operation, such as slotting, facing, プロファイリング, 3D contouring, 荒削り, 仕上げ, or thread machining.

Choosing the right milling cutter type is important for tool life, surface finish, chip removal, and machining stability. 例えば, an end mill cutter is commonly used for slotting and profiling, while a ball nose end mill is better for curved surfaces and mold cavities.

したがって, this guide explains common types of milling cutters, their uses, and how to choose the right cutter type for different CNC machining applications.

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, 曲面, or special profiles.

CNC加工では, the cutter type should match the operation, ワーク材質, 機械剛性, and surface requirement. A wrong cutter type may cause poor surface finish, vibration, chip clogging, or short tool life.

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

エンドミルカッター

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, プロファイリング, ポケットフライス加工, 輪郭を描く, そして肩削り加工.

End mills come in different flute counts, コーティング, 長さ, and carbide grades. 例えば, 2 flute end mills are often used for aluminum because they provide more chip space. 対照的に, 4 flute end mills are often used for steel because they offer better rigidity and cutting stability.

For general CNC milling, 私たちのものを見る エンドミルカッター.

ボールエンドミル

A ball nose end mill has a round cutting tip. This cutter type is used for 3D contouring, 曲面, 金型キャビティ, die machining, and precision finishing.

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

For mold machining and curved surfaces, 選ぶ ボールノーズエンドミル.

ブルノーズエンドミル

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, 見る ブルノーズエンドミル.

Tスロットカッター

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

Usually, an end mill first opens a straight slot. それから, 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スロットカッター.

サイドミーリングカッター

A side milling cutter cuts grooves, スロット, and side surfaces. 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, mold components, and metalworking applications. しかし, the setup must be stable because side cutting can create higher cutting forces.

For groove and side surface machining, 見る サイドフライスカッター.

正面フライスカッター

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

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

Face milling cutters are useful when the workpiece needs a clean, flat, and consistent surface before the next machining step.

スレッドミーリングカッター

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. しかし, it requires proper CNC programming and a stable machining setup.

Thread milling is useful for precision thread machining, but it requires proper CNC programming and a stable machining setup.

ラフィングエンドミル

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. しかし, roughing end mills are not usually used when the final surface finish is the main requirement.

Roughing end mills are suitable for fast stock removal before finishing, especially when machining efficiency is more important than final surface quality.

Diamond-Coated End Mill

Diamond-coated end mills are used for graphite, CFRP, 複合材, 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. しかし, the tool should still match the workpiece material, cutting parameters, そして機械の状態.

For graphite and abrasive materials, 選ぶ ダイヤモンドコーティングエンドミル.

How to Choose Milling Cutter Types by Operation

Different machining operations need different cutter types. したがって, 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, a 2 フルートエンドミル often works well because it provides more chip space.

When cutting steel slots, machinists may choose a 2 フルートとか 4 flute tool depending on slot depth, 冷却剤, と機械剛性.

Cutter Type for Steel Machining

Steel needs stronger cutting edges and better tool rigidity. For this reason, a 4 フルートエンドミル is often used for general steel milling, プロファイリング, and side milling.

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

Cutter Type for Finishing

Finishing requires stable cutting and better surface quality. したがって, many machinists choose 4 フルートとか 6 フルートエンドミル 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. その代わり, ワーク材質を確認してください, 切込み深さ, tool length, コーティング, フルート数, and surface finish requirement.
