정밀 밀링 커터,모든 재료를 가공하는 CNC용 절삭 공구
Roughing end mills remove stock before semi-finishing or finishing. Their serrated cutting edges divide chips into smaller sections, which improves chip control and reduces cutting resistance during suitable rough-machining operations.
The tool name alone does not determine whether a cutter will perform well. The correct design also depends on the workpiece material, 경도, 가공 여유, 커터 직경, 플루트 길이, 기계 강성, 도구 돌출부, 홀더 상태, and cutting strategy.
Our standard offering focuses on solid carbide roughing cutters for CNC machining. HSS and cobalt HSS options are also available for selected conventional machines, larger cutter sizes, lower cutting speeds, or special customer requirements.
Why Use a Serrated Roughing End Mill?
Improved Chip Control
A smooth cutting edge can produce long or continuous chips during heavy cutting. In comparison, a serrated edge divides the chip along the flute and creates smaller chip sections.
This chip-breaking action reduces chip accumulation in pockets and slots. It also lowers the risk of recutting when the flute design, 냉각수 방식, and toolpath match the operation.
Efficient Stock Removal
Roughing cutters are intended for removing machining allowance rather than producing the final surface.
They are commonly used before a semi-finishing or finishing pass in mold cavities, 주머니, 슬롯, 측벽, 단조 부품, cast components, and general CNC-machined parts.
Lower Cutting Resistance
The interrupted serrated edge does not engage the workpiece in the same way as a continuous finishing edge. 결과적으로, the cutting load is easier to manage in suitable roughing operations.
Actual performance depends on the machine, 보유자, 절단 깊이, 방사형 결합, 도구 돌출부, 냉각수 상태, 및 공작물 재료.
Flexible Tool Design
Different machining conditions require different flute counts, serrated pitches, 초경 재종, 코팅, and tool lengths.
Selecting a roughing cutter only by diameter can lead to poor chip evacuation, 진동, 가장자리 손상, 또는 불안정한 공구 수명. We recommend reviewing the complete machining condition before confirming the final specification.
Available Roughing End Mill Options
Solid Carbide Roughing Cutters
Solid carbide is the primary option for modern CNC machining. It provides good rigidity, 내마모성, and cutting stability when the tool geometry matches the workpiece and operation.
Different carbide grades are available for general steel, 스테인레스 스틸, 주철, 티타늄 합금, and selected hardened-material applications.
HSS Roughing Cutters
HSS M2, M35, and M42 roughing cutters are available on request.
These tools can suit conventional machines, lower cutting speeds, larger cutter sizes, 단속 절단, or applications that require greater tool toughness. They are not the main option for high-speed CNC machining, but they remain useful under selected conditions.
Coarse-Pitch Roughing Cutters
Coarse-pitch cutters have wider spacing between the serrated teeth. 그러므로, they provide more chip space and generally suit soft or chip-forming materials.
They are often considered for aluminum, 구리, soft carbon steel, and other applications where chip evacuation is a major concern.
Fine-Pitch Roughing Cutters
Fine-pitch cutters have more closely spaced serrated teeth. They normally provide smoother engagement and more stable stock removal.
They commonly suit carbon steel, 합금강, 스테인레스 스틸, 주철, 티타늄 합금, and selected hardened-steel applications.
The pitch still needs to match the cutter diameter, 가공 여유, 작업, 및 기계 강성.
Multiple Flute Options
We can produce 2-, 3-, 4-, 5-, and 6-flute roughing designs. 하지만, not every flute count suits every cutter diameter or workpiece material.
Fewer flutes normally provide more chip space. 대조적으로, more flutes provide additional cutting edges and can improve stability under suitable conditions.
A 4-flute design is a common choice for general steel roughing, but it should not be treated as a universal solution.
How to Choose Roughing End Mills
공작물 재료로 시작
The workpiece grade and hardness influence the carbide grade, 플루트 수, 톱니 모양의 피치, 코팅, 가장자리 준비, and cutting strategy.
예를 들어, aluminum needs sharp edges and sufficient chip space. Stainless steel requires heat control and stable cutting. Cast iron needs wear resistance, while titanium alloys require careful control of cutting heat and tool engagement.
Confirm the Machining Operation
포켓 황삭, slot roughing, 사이드 밀링, mold roughing, full-slot cutting, and trochoidal milling create different loads on the tool.
A cutter that works well for side roughing may not be the best option for a deep full-width slot. 그러므로, confirm the operation and toolpath before selecting the tool geometry.
Check Machine and Holder Rigidity
긴 공구 오버행, 약한 클램핑, spindle runout, insufficient machine power, and unstable workholding can cause vibration, edge chipping, or premature tool failure.
Use the shortest practical cutter and flute length whenever possible. A rigid holder and stable workpiece setup are also important for heavy stock removal.
Match the Flute Count to Chip Space
A tool with too many flutes may not provide enough chip space for a soft or adhesive material. 반면에, too few flutes may reduce cutting stability in some steel applications.
The final flute count should match the material, 커터 직경, 방사형 결합, 절단 깊이, 도구 경로, and coolant method.
Select the Coating by Material
The coating should support the workpiece material and cutting temperature. It should not be selected only by appearance or price.
Coating selection also needs to consider coolant use, 절단 속도, 기계 안정성, and the required balance between edge sharpness and wear resistance.
Material Selection Guidance
The following recommendations provide a general starting point. The final flute count, 정점, 코팅, 초경 등급, and tool dimensions should match the actual material grade, 경도, 커터 직경, 기계, 및 가공작업.
| 공작물 재료 | Common Tool Direction | 선택 참고 사항 |
|---|---|---|
| 탄소강 및 합금강 | 4-플루트, fine-pitch carbide cutter; TiAlN or AlTiN | Match the carbide grade and coating to hardness, stock allowance, 열을 자르다, and machine power. |
| 스테인레스 스틸 | Fine-pitch carbide cutter; AlTiN or TiSiN | 열 조절, reduce unnecessary tool overhang, and maintain stable chip evacuation. |
| 주철 | Fine-pitch carbide cutter; TiAlN or selected uncoated design | Prioritize edge strength and wear resistance because cast iron can be abrasive. |
| 알루미늄 및 구리 합금 | 2- or 3-flute, coarse-pitch cutter; DLC or uncoated | Use sharp cutting edges and sufficient flute space to reduce chip adhesion and recutting. |
| Titanium Alloys | Application-specific fine-pitch carbide cutter; AlTiN or TiSiN | Control radial engagement, 열을 자르다, 냉각수 공급, 및 도구 오버행. |
| 경화강 | Custom fine-pitch carbide cutter; AlTiN or TiSiN | Selected applications up to approximately HRC 60 require a rigid machine setup, 짧은 오버행, 재고 제거를 통제했습니다.. |
These directions are not fixed rules. Final tool selection should be based on the complete machining condition.
코팅 옵션
TiAlN
TiAlN is commonly considered for carbon steel, 합금강, and selected cast-iron applications. It provides a practical balance of heat resistance and wear resistance for general rough machining.
금
AlTiN provides good heat and oxidation resistance. It can suit steel, 스테인레스 스틸, and selected hardened-material applications.
티신
TiSiN can suit high-temperature cutting and difficult materials such as stainless steel and titanium alloys.
DLC
DLC offers low friction and helps reduce material adhesion when machining aluminum, 구리, 기타 비철재료.
For abrasive high-silicon cast aluminum alloys, such as selected A380 or ADC12 applications, a DLC or another application-specific coating can improve wear resistance.
코팅되지 않은
An uncoated cutter maintains a sharp cutting edge and often suits common wrought aluminum grades such as 6061 그리고 7075.
The exact choice depends on the alloy, 냉각수 방식, 커터 기하학, 및 절단 조건.
주석
TiN is mainly available for selected HSS roughing cutters and conventional machining requirements. It is not normally the first coating choice for modern solid carbide roughing tools.
When a Roughing End Mill May Not Be the Best Choice
A serrated roughing cutter is not suitable for every operation.
It may not be the best choice when:
- The part has only a small amount of stock remaining.
- The operation requires the final surface finish and dimensional tolerance.
- The component has very thin or flexible walls.
- The machine or holder lacks sufficient rigidity.
- The tool requires excessive overhang.
- The material hardness or machining condition exceeds the tool design.
For very large cutter diameters, high stock-removal requirements, or powerful machining centers, an indexable milling cutter may provide a more economical solution.
In other cases, a standard end mill, finishing end mill, or another machining strategy may provide a better result.
Common Selection and Machining Mistakes
Using a Roughing Cutter for Final Finishing
A serrated cutting edge normally leaves a rougher surface than a smooth finishing edge.
Use the roughing cutter to remove most of the stock. Then leave a controlled amount of material for the final finishing pass.
Choosing the Wrong Coating for Aluminum
A coating intended for steel can increase material adhesion when machining aluminum.
Uncoated or DLC-coated surfaces are often more suitable because they support sharp cutting edges and lower friction. The final choice depends on the aluminum grade and coolant condition.
과도한 공구 오버행 사용
Long overhang reduces tool rigidity and increases the risk of vibration.
Use the shortest practical flute length, 목 길이, 그리고 전체 길이. If a deep cavity requires a long tool, adjust the cutter geometry and cutting strategy accordingly.
칩 배출 무시
Poor chip evacuation can cause chip recutting, heat buildup, 가장자리 손상, 그리고 불안정한 절단.
플루트 수, 톱니 모양의 피치, 냉각수, 공기 폭발, 도구 경로, and pocket depth should be considered together.
Selecting Only by Cutter Diameter
Two cutters with the same diameter can perform very differently because of their flute count, 정점, 초경 등급, 코팅, 길이, 가장자리 준비, and shank design.
A correct recommendation requires more than the cutter diameter alone.

Roughing End Mill vs Finishing End Mill
Roughing and finishing cutters serve different stages of the machining process. A roughing cutter removes most of the stock, while a finishing cutter produces the final surface and dimensions.
| Comparison Item | 러핑엔드밀 | Finishing End Mill |
|---|---|---|
| 주요 목적 | 빠른 재고 제거 | Final surface and dimensional control |
| 최첨단 | Serrated or wave-shaped chip-breaking edge | Smooth continuous cutting edge |
| Chip Control | Breaks chips into smaller sections | Usually produces more continuous chips |
| Cutting Load | Suitable for heavier stock removal | Suitable for lighter finishing cuts |
| 표면 결과 | Leaves a rougher surface and finishing allowance | Produces a smoother final surface |
| 일반적인 응용 | 포켓, 슬롯, 옆, 곰팡이, and general roughing | 프로파일링, final sizing, wall finishing, 및 표면 마무리 |
In a typical CNC process, the roughing end mill removes most of the material first. The finishing cutter then removes the remaining allowance and produces the required surface quality and dimensional accuracy.
When the next machining stage requires a smoother surface, final profile, or dimensional control, 우리의 검토 solid carbide finishing end mill solutions.
