Tungsten steel 3-edge round nose milling cutter suitable for deep cavity processing

The 3-edge aluminum round nose milling cutter designed for high-precision processing of aluminum alloys has been officially launched. With tungsten steel material, nano-coating and R angle parameter customization technology, it significantly improves cutting efficiency and surface quality, and is suitable for high-end manufacturing needs such as aerospace, 3C electronics, etc.

Technological breakthrough

55° helix angle design: optimizes chip removal path, reduces aluminum sticking phenomenon, cutting line speed can reach more than 300m/min, and efficiency is 40% higher than traditional tools.

Nano coating (TS/TIALN): reduces friction coefficient, extends tool life to twice that of ordinary milling cutters, and is suitable for continuous processing of hard aluminum alloys such as 6061 and 7075.

R angle accuracy ±0.02mm: supports R0.2-R3.0 customized parameters, taking into account plane milling and surface finishing, reducing the number of tool changes.

Application scenario expansion

Deep cavity processing: extended specifications (150-200mm) meet the deep groove processing requirements of mobile phone middle frames, automotive die-casting molds, etc.

High gloss surface treatment: precision edge grinding process makes the surface roughness of the machined surface stable below Ra0.8μm, suitable for mirror polishing requirements.

User value

Cost optimization: supports professional grinding and regeneration services, and the cost of a single grinding is only 30% of the price of a new knife.

Non-standard adaptation: open blade diameter (D4-D20), helix angle (45°-65°) and other parameters can be customized to cover 99% of aluminum processing scenarios.
