Our Product Lines

3 Core Product Lines

Engineered for the most demanding precision machining applications -- each line purpose-built for a specific material challenge.

Titanium alloy machining end mills
Product Line 01
Aluminum · Automotive · Consumer Electronics

Aluminum End Mills

Engineered for high-speed, high-precision milling in aluminum alloys. Our specialized series features optimized geometries that eliminate surface chatter and light/dark inconsistencies, delivering an ultra-clean, mirror-level finish on complex and thin-walled components.

  • Engineered geometry ensures stability when machining thin-walled profiles and large frames.
  • Mirror-grade Ra ≤ 0.2 μm roughness, eliminating surface defects and vibration lines.
  • High-polish 3-flute design with large chip pockets prevents built-up edge.
  • Premium DLC / ZrN coating prevents aluminum sticking for extended tool life.
  • Diameter range: Ø1mm - Ø25mm,with custom profile options.
