What Type of Cutters Are Most Used on Vertical Milling Machines?

Most Frequently Used Cutting Tools in Vertical Milling Machines
Vertical milling machines (VMCs) are essential for machining planes, grooves, e contornos 3D complexos. 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
Aplicações:

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

Technical Advantages:

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

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

2. Ball Nose End Mill
Aplicações:

• 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
Principais características:

• 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
Aplicações:

• Mold draft angles
• Precision narrow slotting
• Hole enlargement

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

6. Keyseat Cutter
Aplicações:

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

7. Drill Mill
Aplicações:

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

Benefit: Multifunctional design reduces tool changes.

End Mill Selection Framework: Material, Stage, Machine

Material-Specific Solutions

Machining Phase Strategy

• Roughing: High-feed end mills (≥0.15mm/tooth) + trochoidal paths
• Semi-Finishing: Corner radius end mills + helical interpolation
• Finishing: Ball nose tools with 0.05mm stepover (Ra0.8μm achievable)

Machine Optimization

• Long overhangs: Anti-vibration holders + <10mm tools (L:D ratio <5:1)
• High-speed spindles: G1-grade balanced tools
