When machining ductile materials like red copper or aluminum, the biggest challenge is “stickiness.” The SAMHO DLC-Coated Series solves this with a specialized surface treatment that acts as a solid lubricant, delivering mirror-like surface finishes and significantly extended tool life.
Advanced Technical Features
1. DLC Coating for Ultra-Low Friction & Non-Stick Performance
The Diamond-Like Carbon (DLC) coating provides exceptionally low friction and anti-adhesion properties. This is critical for:
- Resisting Built-Up Edge (BUE): Preventing material from welding to the cutting edge
- Cleaner Cuts: Reducing tool wear in soft, sticky materials like red copper and resin-based plastics
2. Mirror-Finish Flutes for Rapid Chip Evacuation
Every flute is polished to a mirror finish. This open, high-lubricity geometry enables:
- Smooth Chip Flow: Preventing chip recutting and tool clogging during high-speed CNC operations
- Dimensional Stability: Maintaining accuracy over long production runs by reducing heat buildup
3. Optimized Ball Nose Profile for 3D Surface Finishing
The precision-ground spherical tip is ideal for:
- Electrode Machining: Achieving tight tolerances in high-purity copper
- 3D Mold Profiling: Finishing curved surfaces and free-form geometries with minimal tool marks
- Complex Cavities: Reaching deep features in aluminum and resin tooling
4. Tested Cutting Parameters for Out-of-the-Box Performance
SAMHO provides field-tested cutting data for red copper and aluminum. These parameters (RPM, feed rate, depth of cut) minimize trial and error, ensuring stable and repeatable machining results from the first cut
Target Materials & Industries
