Aerospace Examples
Bel Air develops mass finishing processes for customers in the aerospace industry. Below are examples of deburring aerospace components, super polishing turbine blades, & parts refurbishing using our vibratory tumblers, high-energy finishers, & drag finishers. We also developed processes for deburring and polishing blisks, brackets, compressor discs, & aircraft housings.
Jet Engine Compressor Blade Polishing
Objective | Ultrapolish |
|---|---|
Part Description | Compressor Blade |
Material | A-Series Steel |
Process Type | AutoHone – Metal Tumbler Polishing Machine |
The customers goal was to establish the best way to match a micro tech surface finish to achieve a super or ultra polish of less than Ra 6 µin.
Gear teeth Deburring
| Objective | Deburr Gear Teeth |
|---|---|
| Part Description | Gears |
| Material | Steel |
| Process Type | Centrifugal Disc |
Bel Air was tasked with creating a faster, more efficient low cost method of removing burrs from the gear teeth without a secondary machining operation.
Compressor Blade Grinding
Objective | Ultrapolish |
|---|---|
Part Description | Compressor Blade |
Material | 17- PH Stainless Steel |
Process Type | High Energy |
These compressor blades originally had contour machining lines removed by hand grinding. They also had to have the surface reduced from an Ra of 54 µin to an Ra of less than 10 µin.
Bel Air was able to automate this and get the surface to an Ra of 8 µin.
