Milling Machine Tools: Names, Tipos, and Uses for CNC Machining

Milling machine tools are cutting tools for milling machines and CNC machining centers. They remove material from metal, plastic, graphite, and other workpieces to create slots, holes, perfis, flat surfaces, threads, and 3D shapes.

Para compradores, engineers, and machinists, choosing the right milling tool is important. Como resultado, the correct cutter can improve surface finish, reduce tool wear, and make machining more stable.

No entanto, different tools have different shapes and functions. Portanto, this guide explains the most common milling machine tools, their names, their uses, and how to choose the right tool for different CNC milling operations.

What Are Milling Machine Tools?

Manufacturers use milling machine tools as rotary cutting tools for milling operations. These tools usually have one or more cutting edges. When the tool rotates, the cutting edges remove material from the workpiece.

Many factories use these tools in mold making, fabricação de máquinas, automotive parts, aerospace parts, electronic components, and general metalworking. Common milling tools include end mills, moinhos de face, fresas de ponta esférica, bull nose end mills, Cortadores de ranhura em T, side milling cutters, thread milling cutters, drills, and reamers.

In simple words, milling machine tools help manufacturers cut different shapes with accuracy, estabilidade, and repeatability.

Main Types of Milling Machine Tools

Cortadores de moinho de extremidade

End mill cutters are among the most common milling machine tools. They can cut from the side and the end of the tool. Because of this design, they are suitable for slotting, perfil, contorno, pocket milling, and shoulder milling.

End mills are available in different flute numbers, revestimentos, comprimentos, and materials. Por exemplo, 2 flute end mills are often used for aluminum and soft materials because they offer better chip removal. Em contraste, 4 flute end mills are more suitable for steel and stainless steel because they provide stronger cutting stability.

For general CNC machining, an end mill cutter for CNC milling.is usually one of the first tools to consider.

Fresas de ponta esférica

Ball nose end mills have a round cutting tip. This design makes them suitable for 3D surface machining, superfícies curvas, cavidades de molde, and complex contours.

Mold shops often use ball nose end mills for die machining, graphite machining, and precision finishing. Compared with flat end mills, ball nose tools can produce smoother curved surfaces. No entanto, they are not the best choice for sharp inside corners.

When machining 3D profiles and mold cavities, fresas de ponta esférica are a better choice.

Bull Nose End Mills

As fresas de topo de ponta também são chamadas de fresas de topo com raio de canto. They have a small radius on the cutting corner. This radius improves tool strength and reduces corner chipping.

Como resultado, bull nose end mills work well for semi-finishing, rough finishing, and machining materials such as steel and stainless steel. They are also a good choice when the tool needs more corner strength than a sharp flat end mill.

For stronger corner cutting and semi-finishing, see fresa de topo de nariz de touro.

T-Slot Cutters

T-slot cutters cut T-shaped slots in machine tables, jogos, moldes, and clamping systems. This tool usually works after a straight slot has already been made.

First, an end mill opens the slot. Então, the T-slot cutter creates the wider undercut area. Portanto, you should not use a T-slot cutter as the first tool for opening a straight slot.

For slot and undercut machining, you can use a T-slot cutter.

Side Milling Cutters

Side milling cutters cut grooves, slots, and side surfaces. They remove material from the side of the workpiece and help machine wider or deeper grooves.

Em muitos casos, factories use these cutters for general machinery, peças de molde, and metal component production. They are suitable when the cutting operation needs stable side cutting.

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

Ferramentas de corte de metal duro

Solid carbide cutting tools are widely used in modern CNC machining. Carbide has higher hardness and better wear resistance than high-speed steel. Portanto, it supports higher cutting speeds and longer tool life.

Many manufacturers choose solid carbide tools for steel, aço inoxidável, ferro fundido, alumínio, cobre, graphite, and hardened materials. Além disso, coatings can improve heat resistance and wear resistance.

For high-precision CNC machining, you can choose ferramentas de corte de metal duro.

How to Choose Milling Machine Tools by Operation

Different milling operations need different tool designs. Portanto, you should choose the tool based on the cutting task first.

For Slotting

End mills are usually the most common choice for slotting. Um 2 flute end mill is useful for aluminum and other soft materials because it has more chip space. Enquanto isso, um 4 flute end mill is better for steel when higher stability is needed.

For aluminum and slotting, see 2 moinho de extremidade de flauta.

For Side Milling and Profiling

When you need side milling, choose an end mill with good rigidity and a suitable flute length. If the workpiece material is harder, coated carbide end mills can improve tool life.

For steel machining, see 4 moinho de extremidade de flauta.

For 3D Surface Machining

For 3D surfaces, curved profiles, and mold cavities, ball nose end mills are more suitable. Their round tip can follow complex tool paths and produce smooth surfaces.

For mold and 3D surface machining, see fresas de ponta esférica.

For T-Slot Machining

Use a T-slot cutter for T-slots and undercuts. No entanto, do not use it for the first straight slot. First, use an end mill to make the opening. Então, use the T-slot cutter to finish the special shape.

For undercut machining, see T-slot cutter.

For Graphite and Abrasive Materials

Graphite and other abrasive materials can wear normal tools quickly. Por esta razão, many graphite machining shops choose diamond-coated tools because they improve wear resistance and keep the cutting edge sharper for longer.

For graphite machining, choose diamond-coated end mills.

How to Choose Milling Tools by Material

Além disso, material is one of the most important factors when choosing milling machine tools. A tool that works well for aluminum may not work well for stainless steel or graphite.

Alumínio

Aluminum is soft, but it can stick to the cutting edge if chip removal is poor. Por esta razão, tools with fewer flutes and polished flutes are often preferred. Um 2 flute or 3 flute end mill can help remove chips smoothly.

Aço

Steel needs stronger cutting edges and better tool rigidity. Em muitos casos, 4 flute carbide end mills are suitable for steel milling. Coated tools can also improve heat resistance and tool life.

Aço inoxidável

Stainless steel is more difficult to machine because it can generate heat and work harden. Portanto, you need a sharp carbide tool, stable clamping, and a suitable coating. Proper cutting parameters are also important.

Grafite

Graphite is abrasive, so tool wear is a major problem. Diamond-coated end mills are often used because they provide better wear resistance and longer tool life.

Aço Endurecido

Para aço endurecido, tool hardness, revestimento, desenho de flauta, and rigidity are very important. High-performance carbide end mills or special coated tools are usually required.

Milling Machine Tools Selection Checklist

Before choosing milling machine tools, check the points below. This can help reduce wrong tool selection and improve machining efficiency.

Portanto, a correct tool choice should match the material, cutting operation, machine condition, and surface finish requirement. It is better not to choose a milling cutter only by price. Em muitos casos, a more suitable cutter can reduce tool wear, improve surface finish, and lower the total machining cost.
