In the production of EDM electrodes and aluminum components, tool adhesion is the primary cause of poor surface finish and tool breakage. The SAMHO DLC-coated flat end mill combines a solid lubricant surface with high-rigidity carbide to deliver mirror-like finishes in non-ferrous machining.
Advanced Technical Features
- DLC Coating for Ultra-Low Friction & Non-Stick Cutting
The DLC coating provides exceptionally low friction and high surface hardness, essential when machining red copper and aluminum:
- Resists Built-Up Edge (BUE): Prevents material from welding to the cutting edge
- Reduces Cutting Heat: Allows higher speeds and feeds under dry or MQL conditions
- Optimized 2-Flute Design for Rapid Chip Evacuation
Ductile materials like pure copper and soft resins produce long, gummy chips. The open 2-flute geometry ensures:
- Maximum Chip Space: Prevents clogging and chip recutting in deep slots
- Clean Cutting Action: Burr-free edges and accurate vertical shoulders
- Mirror-Polished Flutes for Superior Surface Finish
Mirror-polished flute surfaces reduce friction during chip flow, ensuring:
- Dimensional Accuracy: Minimizes tool deflection caused by radial forces
- High Surface Quality: Delivers out-of-the-box mirror finishes on high-purity copper parts
- Application-Specific Cutting Parameters
SAMHO provides field-tested cutting data for copper, aluminum, and resins to optimize RPM, feed rates, and minimize setup time and tool failure risk
