정밀 밀링 커터,모든 재료를 가공하는 CNC용 절삭 공구
CNC 가공에서, 2날 엔드밀과 4날 엔드밀은 모두 필수 공구입니다.. 겉모습은 비슷하지만, choosing wrong can impact efficiency and costs. We’ll break down their differences in structure, 애플리케이션, and selection.
Core Differences
| 특징 | 2-플루트 엔드밀 | 4-플루트 엔드밀 |
|---|---|---|
| 칩 공간 | Large | 작은 |
| 칩 배출 | Excellent (aluminum/plastics) | Limited (prone to clogging) |
| 최첨단 | 2 | 4 |
| 이송 속도 | 낮추다 | 더 높은 |
| 표면 마감 | 좋은 | Excellent |
| Best Materials | 알류미늄, 목재, soft plastics | 강철, 스테인레스 스틸, hard plastics |
| Best Operations | 깊은 슬롯, 황삭 | 마무리 손질, 얇은 벽 |
1. Structural Differences
최첨단
2-플루트:
- Wider cutting edges
- Better for material removal
4-플루트:
- Double the edges
- Higher feed capability
칩 배출
- 2-플루트: 50% more space
Prevents clogging with gummy materials
- 4-플루트: Compact design
For short-chipping metals only
2. Material Selection Guide
| 재료 | 권장 도구 | 왜? |
|---|---|---|
| 알루미늄/목재 | 2-플루트 | Prevents chip welding |
| 강철/주철 | 4-플루트 | Better heat dissipation |
| Titanium/Alloys | Test both | Coating-dependent performance |
3. 성능 비교
| 매개변수 | 2-플루트 | 4-플루트 |
|---|---|---|
| Surface Roughness | Ra 3.2-6.3μm | Ra 1.6-3.2μm |
| 속도 범위 | 800-3,000 RPM | 1,500-5,000 RPM |
4. 3-Step Selection
단계 1: Check Material
- Soft (HB<200) → 2-flute
- Hard (HB≥200) → 4-flute
단계 2: 작업 유형
- Roughing → 2-flute
- Finishing → 4-flute
단계 3: 기계 동력
- Low power → 2-flute
- High-speed CNC → 4-flute
Cost Analysis
2-플루트:
- Lower initial cost
- Replace when worn
4-플루트:
- Higher upfront cost
- Can be reground
Summary
2-flute end mills excel in aluminum/soft materials with superior chip evacuation, while 4-flute versions deliver better finishes on steel/hard materials. Choose based on material hardness, 작업 유형 (roughing vs finishing), and machine capability. Always test critical applications
