Blisk [Blade In Disk]
Conventionally, each rotor blade of a jet engine is installed on a disk due to problems with heat expansion.
Blisk (Blade In Disk) is a single module, unifying the blade and disk, enabled with new design method.
This is a sample machined with five axis synchronized machining center.
Material:Aluminum alloy (A5056)
External Diameter: (φ)300mm
Number of Blade: 40
Length of Blade: 75mm
Thickest Part of Blade: 2.5mm
Thinnest Part of Blade: 0.5mm
Processor: Vertical Five-Axis Synchronized Machining Center
Finishing Tool: R3Ball End Mill
Processing Time: 120min. approx. per blade
Heat resistant alloys such as inconel is commonly used; here, we used aluminum alloy for thinning the module.
The focal point of this machining is absence of any cracks generally inevitable in conventional machining.
