CUMI ABRASIVE WHEELS IN AEROSPACE & DEFENCE MANUFACTURING APPLICATIONS

Engineering Surfaces. Making Materials Matter

CUMI in Aerospace – Creep Feed Grinding Application

Aircraft Turbine Engine

Critical turbine blade/vane root serrations that are precision grinded

Aircraft Turbine Engine

Creep Feed Grinding of Turbine Blade Root Serrations

Creep feed grinding

Surface grinding with high stock

removals (depth of cut) in one pass on

complex shaped parts

Turbine Blade Fir Tree root grinding application

Creep feed grinding wheels are used to

grind turbine blade/vane root serrations

(fir trees) in aircraft engines

Criticality

• Tolerance band of ± 0.012 mm on the fir-tree profile

• No burns on the Inconel alloy material

• No stress development on the material

– Power drawn to be minimal during

CUMI’s Creep Feed Grinding Wheels

Popular CUMI grades
