CFRP Plate
Descripción
The aircraft industry uses the longer more CFK and other with carbon fibres reinforced materials. HEULE, having been active at the forefront of CFK machining for quite some time now, carried out trials for this customer and developed a solution.
Application details
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

Proposed solution
Proposed solution
HEULE developed a special tool based on the COFA C3. The carbide blade has a cutting geometry that is optimized for CFK and is coated.
Machining parameters:
- Speed: 2000 U/min
- Feed: 0.04 mm/U
Customer benefits
Customer benefits
The picture shows on the left the bore entry and on the right the bore exit after the deburring.
The difficulty in deburring bores in carbon-reinforced materials is to cut the fibres neatly and not fray them. Furthermore, these materials are very abrasive which leads to heavy wear on the cutting edge of the blade.
Customer satisfaction
Customer satisfaction
The customer is satisfied by the deburring result and by the tool life of the blade. The next step now is to implement the new procedure into production.
