Why Choose Dohre for Aerospace

• 

  Customized Tool Design

  Every aerospace part has unique geometry and tolerance requirements. Dohre’s engineers team work closely with clients to design tools with optimized flute geometry, helix angles, edge preparation, and corner radii—perfect for both 3-axis and 5-axis machining.
• 

  Tight Tolerances, Perfect Surfaces

  With machining precision up to ±0.002mm and surface roughness below Ra 0.2μm, our tools meet the demands of mission-critical aerospace applications like engine blades, casings, and  landing gear parts.
• 

  Advanced Coating Technologies

  Dohre tools feature PVD or CVD coatings such as AlTiN, TiAlSiN, or nano-layered composites.  These coatings dramatically improve heat resistance, oxidation stability, and chip evacuation, especially when machining titanium or nickel-based alloys.
• 

  Global Equipment, Global Standards

  We use imported high-end 5-axis CNC grinders and fully automated measuring systems from  Germany, Switzerland, and Japan to deliver world-class consistency and accuracy.

Customer Reviews

• “We’ve been working with Dohre’s aerospace-grade end mills for over a year, especially on aluminum structural components. The dimensional stability and surface finish are consistently excellent — even on thin-walled, high-speed operations. Their tool performance has reduced our finishing time by over 20%.”
