Deburring Bores in Composite Aircraft Parts
Challenge
There are two major challenges to machining composites: one is to cut the fibers neatly without fraying; the other is that the abrasiveness of the material leads to heavy wear on the cutting edge of the tool blade. HEULE worked with this aircraft manufacturer to develop a cost-effective solution (a tool with a long blade life) that would also deburr the bore neatly.
Application details
- Bore-Ø: 4.81 mm
- Material 1: CFRP (Carbon fiber-reinforced plastic)
- Material 2: GFRP (Glass fiber-reinforced plastic)
- Machine: Mori Seiki NV5000 / 4 Axis Milling Machine
- Processing: Vertical Machining
Solution
HEULE developed a special tool based on the COFA C3. The carbide blade has a cutting geometry that is optimized for composites and is coated.
Machining parameters:
- Speed: 2000 U/min
- Feed: 0.04 mm/U
Results
The customer is satisfied by the deburring result and by the tool life of the blade.
