Superalloy Blade Cooling Holes Machining

Workpiece

Superalloy
Hole: φ0.5/0.6/0.7mm

28 - Conprofe Technology Co., Ltd.

Challenges (Laser+EDM)

Long cycle time with EDM: 150s
Engine blade service life shortened by EDM recast layer

Benefits

Lower cutting force and significant burr reduction
Qualified hole dimensional accuracy
Hole wall roughness decreased by 88%, from 1.629μm to Ra 0.181μm
Cycle time shortened by 40%
