From turbine blades to fuselage panels, aerospace manufacturing demands perfection. CUMI’s aerospace abrasive solutions are built for extreme precision, safety, and consistency—delivering flawless grinding and finishing across critical aerospace components. Whether it’s prepping composite surfaces or achieving ultra-smooth finishes on high-performance alloys, CUMI ensures tight tolerances compliance and minimal heat with controlled material removal and high quality surface finish.
For critical dimensional accuracy in structural parts, landing gear, turbine blades, and fastners—CUMI abrasives remove stock efficiently without compromising the substrate.
Product Options:
Ideal for prepping composite surfaces, smoothing fuselage panels, and cleaning weld seams before final inspection. Offers superior control for both manual and automated sanding systems.
Product Options:
Application-specific products for engine, airframe, or interior component manufacturing.
Uniform grit and bonding ensure repeatable outcomes across large production runs.
Long-lasting abrasives that reduce changeovers in high-volume environments.
CUMI’s team collaborates with your engineers for process optimization and spec compliance.
Using CUMI’s micro-grit sanding belts and sheets, along with proper sequence progression (e.g., 180 → 240 → 320), helps maintain fiber integrity while achieving a uniform finish.
CUMI’s non-woven wheels and fine-grit flap discs are excellent for achieving satin or mirror finishes on aluminum without gouging or overcutting.
CUMI offers specially formulated silicon carbide wheels and coated abrasives that minimize heat generation and prevent contamination—ideal for high-performance alloys like titanium, Inconel, and Hastelloy.
Contamination is a critical concern in aerospace, especially when working with titanium, composites, or other high-performance alloys where even trace impurities can affect bonding, coating, or fatigue resistance. To minimize contamination:
