Introduction
Choosing the right end mill is key for machining aluminum. 이 기사에서는 4플루트 엔드밀이 좋은 선택인지 살펴봅니다., 그들의 장점을 커버, 단점, and best uses to help you improve efficiency and finish.
What is a 4-Flute End Mill?
A 4-flute end mill has four cutting edges. It’s used for milling, 슬로팅, 그리고 컨투어링. It offers higher removal rates and better stability than tools with fewer flutes. Common coatings like TiAlN reduce aluminum adhesion.
Key Challenges in Aluminum Machining
Aluminum is soft and sticky, leading to built-up edge on tools. Its chips are long and can clog flutes. Heat builds up quickly due to high conductivity. Alloys with silicon are abrasive and wear tools faster.
Advantages
Higher machining efficiency and feed rates.
Better surface finish with less vibration.
Good rigidity for stable cutting.
Improved chip control with right helix angle.
Longer life due to even wear distribution.
Limitations
Narrow flutes can cause chip clogging.
Higher cutting force risks part deflection.
Aluminum may stick to the cutting edge.
Not ideal for deep slots or heavy roughing.
Wears faster in high-silicon aluminum.
When to Use?
✅ Use for finishing, semi-finishing, and side milling where finish and precision matter.
⚠️ Avoid for deep slots, heavy cuts, or unstable setups.
🔧 Use high helix tools, 코팅, and high-pressure coolant.
Alternative End Mills
2-플루트: Best for roughing and deep slots.
3-플루트: Balanced choice for roughing and finishing.
Specialized tools: Designed for high-speed aluminum machining.
결론
4-flute end mills work well for aluminum finishing, offering good surface quality and speed. But for roughing or deep cuts, prefer 2 or 3-flute end mills for better chip removal. Always match the tool to your specific job.
