Main Applications of Milling Cutters
Facing Flat Surfaces
Facing is one of the most common milling operations. It creates a flat surface on the top of a workpiece. This operation is often used for mold bases, machine parts, fixture plates, and metal blocks.
Machinists usually choose face milling cutters for large flat areas. 하지만, end mills can also perform facing on smaller parts or when the machine setup requires more flexibility.
결과적으로, facing is useful when the workpiece needs a clean, flat, and accurate surface before the next machining step.
Slotting and Groove Milling
Milling cutters are also used for slotting and groove milling. In this operation, the cutter removes material to create straight slots, keyways, T-slots, 또는 그루브.
Many machinists use end mills for straight slots. For special T-shaped slots, first use an end mill to open the straight slot. Then, use a T-slot cutter to create the undercut shape.
For T-slot and undercut machining, 보다 T-slot cutter.
Profiling and Side Milling
Profiling means cutting along the side of a workpiece to create a shape, contour, or outside edge. Side milling also removes material from the side surface.
End mill cutters are commonly used for these operations because they can cut from the side and the end of the tool. 게다가, they are suitable for pockets, 어깨, 측벽, and general CNC milling.
For steel, 알류미늄, and stainless steel machining, an end mill cutter for CNC milling is a practical choice.
3D Contouring and Mold Machining
For curved surfaces, 금형 구멍, and complex 3D shapes, Mold shops often choose ball nose end mills for curved surfaces and mold cavities. Their round cutting tip can follow curved tool paths and create smoother surfaces.
This makes them useful in mold making, 다이 가공, 흑연 전극 가공, and precision parts manufacturing. 하지만, ball nose tools are not the best choice when the part requires sharp inside corners.
For curved surfaces and mold cavities, choose 볼 노즈 엔드밀.
Semi-finishing and Corner Strength
Some machining operations need stronger tool corners. 이 경우, bull nose end mills, also called corner radius end mills, are a good choice.
A bull nose end mill has a small radius on the cutting corner. This radius helps reduce chipping and improves tool strength. 그러므로, it is often used for semi-finishing, rough finishing, and machining steel or stainless steel parts.
For stronger corners and semi-finishing, 보다 불 노즈 엔드밀.
Roughing and Fast Material Removal
Roughing removes a large amount of material before finishing. The goal is not to create the final surface, but to remove stock quickly and prepare the part for later machining.
Roughing end mills usually have special flute designs that break chips into smaller pieces. This can reduce cutting pressure and improve chip evacuation.
하지만, roughing tools should match the machine rigidity, workpiece material, tool holder, and cutting parameters. Otherwise, vibration and tool wear may increase.
Milling Cutter Uses by Tool Type
Different cutter types are designed for different machining jobs. The table below gives a simple comparison.
| 커터 종류 | 주요 용도 | 최고의 대상 |
|---|---|---|
| 엔드밀 커터 | 슬로팅, 프로파일링, 포켓 밀링 | General CNC milling |
| 볼 노즈 엔드밀 | 3D contouring and curved surfaces | Mold and die machining |
| 불 노즈 엔드밀 | Semi-finishing and corner strength | Steel and stainless steel |
| T-슬롯 커터 | T-slots and undercuts | Fixtures and machine tables |
| 페이스 밀링 커터 | Flat surface machining | Large surface finishing |
| 사이드 밀링 커터 | Side cutting and grooves | Slots and side surfaces |
| 스레드 밀링 커터 | Thread machining | Internal and external threads |
| Diamond-Coated Cutter | Abrasive material machining | Graphite and composites |
How to Choose CNC Milling Cutters by Material
게다가, material is one of the most important factors when choosing CNC milling cutters. A cutter that works well for aluminum may not work well for stainless steel or graphite.
| 공작물 재료 | Suggested Cutter | Main Reason |
|---|---|---|
| 알류미늄 | 2 flute or 3 플루트 엔드밀 | Better chip removal |
| 강철 | 4 플루트 초경 엔드밀 | Better stability |
| 스테인레스 스틸 | Coated carbide end mill | 더 나은 내열성 및 내마모성 |
| 석묵 | Diamond-coated end mill | Longer tool life |
| 경화강 | High-performance coated carbide tool | 더욱 강력해진 절삭날 |
| Plastic | 1 flute or 2 flute tool | Reduces chip clogging |
Milling Cutters for Aluminum
Aluminum is soft, but it can stick to the cutting edge if chip removal is poor. 그러므로, 2 flute or 3 flute end mills are often used for aluminum machining.
These tools provide more chip space and help remove chips from the cutting area. 게다가, sharp cutting edges and polished flutes can improve cutting stability.
For aluminum slotting and soft materials, choose 2 플루트 엔드밀.
Milling Cutters for Steel
Steel needs stronger tool rigidity and stable cutting performance. 이러한 이유로, Many factories choose 4 flute carbide end mills for steel milling.
에이 4 flute design provides more cutting edges and better tool strength than a 2 flute cutter. 결과적으로, it is suitable for side milling, 프로파일링, 마무리 손질, and general steel machining.
For steel and general CNC milling, 보다 4 플루트 엔드밀.
Milling Cutters for Stainless Steel
Stainless steel can generate heat and work harden during machining. 그러므로, 커터의 모서리는 날카로워야 합니다., 적합한 코팅, and stable flute design.
많은 경우, coated carbide milling cutters are better than uncoated tools. 하지만, coolant, tool holding, 기계 강성, and cutting parameters are also important.
For high-performance carbide tools, 보다 초경 엔드밀 커터.
Milling Cutters for Graphite
Graphite is abrasive, so tool wear is a major issue. 이 경우, diamond-coated milling cutters can improve wear resistance and extend tool life.
Diamond-coated end mills are often used for graphite electrodes, 금형 가공, and other abrasive material applications.
흑연 가공용, choose diamond-coated end mills.
How to Choose Milling Cutters by Machining Operation
Besides material, Besides material, the machining operation also affects cutter selection. 그러므로, you should choose the cutter based on the cutting task.
| Machining Operation | Recommended Cutter | Selection Tip |
|---|---|---|
| 슬로팅 | End mill cutter | Use enough chip space |
| T-slot machining | T-slot cutter | Open the slot first with an end mill |
| Facing | Face mill or end mill | Choose based on surface size |
| 프로파일링 | End mill cutter | Check flute length and rigidity |
| 3D 컨투어링 | 볼 노즈 엔드밀 | Use for curved surfaces |
| 준마무리 | 불 노즈 엔드밀 | Better corner strength |
| 마무리 손질 | 4 flute or 6 플루트 엔드밀 | Better surface finish |
| Graphite machining | Diamond-coated end mill | Better wear resistance |
Finishing requires stable cutting and a better surface finish. 그러므로, many machinists choose 4 flute or 6 flute end mills when chip evacuation is not a major problem.
For finishing and stable side milling, 보다 6 플루트 엔드밀.
For Custom CNC Machining
Some parts require special diameters, longer flute lengths, special coatings, or non-standard shapes. 이 경우, custom milling cutters may be required.
If standard tools cannot meet the drawing or material requirement, you can consider custom CNC milling cutters based on the part design and machining condition.
