1. Basic Knowledge: Direction of Cut (Geometry Analysis)
Upward Chip Removal
Pulls chips upward away from the material. Offers fast cutting and low resistance, but may leave burrs on the top surface.
- • Recommended: Acrylic, Aluminum, Solid Wood
- • Advantage: Superior chip evacuation, heat reduction
Downward Chip Pressure
Pushes chips downward. Provides an exceptionally clean finish on the top surface but requires careful heat management.
- • Recommended: Thin sheets, Laminates, Plywood
- • Advantage: No top-surface splintering, stabilizes work
Dual-Direction Pressure
Combines both geometries to pull chips toward the center. Leaves both top and bottom surfaces perfectly clean.
- • Recommended: Double-sided laminates, Premium Plywood
- • Advantage: Ultimate edge finish on both sides
Editor's Tip: Why Tungsten Carbide?
Tungsten Carbide is significantly harder than standard HSS (High-Speed Steel), ensuring longer tool life and higher precision in demanding CNC operations. All SSOBOM tools are crafted from premium-grade carbide raw materials.
2. Efficiency Comparison by Number of Flutes
| Category | Single Flute (1-Flute) | Two Flutes (2-Flutes) | Multi-Flutes (3+) |
|---|---|---|---|
| Chip Space | Extremely Large (Best) | Moderate | Narrow |
| Feed Rate | Very Fast | Optimal Balance | Stable but slow chip removal |
| Surface Finish | Coarse | Smooth | Very Fine/Polished |
| Best Materials | Acrylic, Plastic, Soft Aluminum | Hardwood, MDF, Softwood | Metal Work, Fine Finishing |
💡 Key Formula: RPM vs. Feed Rate
Feed Rate = RPM × Flutes × Chip Load
※ Increasing RPM isn't always the solution. You must set an appropriate feed rate for your flute count to prevent tool breakage or overheating.
3. Material Matching Guide
Tool Maintenance & Safety
Collet Cleanliness: Keep the collet free of debris to prevent runout, which causes premature tool failure.
Ramp Your Entry: Use a ramping move for vertical entry instead of a direct plunge to reduce impact stress.
