Most Frequently Used Cutting Tools in Vertical Milling Machines
Vertical milling machines (VMCs) are essential for machining planes, grooves, and complex 3D contours. Tool selection directly impacts efficiency and finish quality. This guide explores key end mill cutter types and selection logic for machining success.

Core End Mill Cutter Types: From General to Specialized
1. Flat End Mill
응용:

• Face milling
• Square shoulder milling
• Slotting (mold bases, mechanical components)

기술적 장점:

• 4-6 flute carbide body (ISO P20-P40)
• Coarse pitch design (>8mm) improves chip evacuation

User Tip: Use DLC coating for aluminum to prevent material adhesion.

2. Ball Nose End Mill
응용:

• 3D contour finishing
• Aerospace blade profiling
• Artistic engraving

Variants:

• Single-flute: Cost-effective for manual regrinding
• Indexable multi-flute: R0.5-R6mm radius, IT5 precision

Performance: Achieves Ra0.4μm finish in 5-axis machining.

3. Corner Radius End Mill
주요 특징:

• 0.5-3mm radius reduces stress concentration
• 30°-45° helix angle balances cutting forces
• Case Study: Automotive molds achieved 120-minute tool life on HRC45 steel with R2mm tools.

Case Study: Automotive molds achieved 120-minute tool life on HRC45 steel with R2mm tools.

4. Roughing End Mill
Efficiency Metrics:

• Serrated edges boost material removal by 30%
• Reduces cutting forces by 25%
• MQL decreases coolant use by 80%

5. Tapered End Mill
응용:

• Mold draft angles
• Precision narrow slotting
• Hole enlargement

Advantage: 1°-15° taper angle improves vibration resistance.

6. Keyseat Cutter
응용:

• Shaft keyways
• Gear splines
• 설계: Full-radius edges ensure ±0.01mm sidewall perpendicularity.

7. Drill Mill
응용:

• Combined drilling/milling
• Deburring
• Small-batch prototyping

Benefit: Multifunctional design reduces tool changes.

End Mill Selection Framework: 재료, Stage, Machine

Material-Specific Solutions

Machining Phase Strategy

• 황삭: High-feed end mills (≥0.15mm/tooth) + trochoidal paths
