Carbon Fiber Reinforced Polymers PCD Carbide End Mills High-Speed Machining

Introduction:

• PCD (Polycrystalline Diamond): A synthetic diamond layer sintered onto a carbide substrate, offering extreme hardness (2nd only to natural diamond) and wear resistance.

• Carbide Body: Provides structural strength and rigidity while allowing for tool geometries like flutes, angles, and coatings.

Features:

1. Why PCD for CFRP?

• Extreme Abrasiveness: Carbon fibers rapidly wear down carbide tools. PCD (Polycrystalline Diamond) offers superior wear resistance.

• High-Speed Capability: Can run at 1,000–4,000 m/min (vs. 200–800 m/min for carbide).

• Clean Cuts: Minimizes delamination, fraying, and fiber pull-out.

• Long Tool Life: 5–20x longer than carbide in CFRP machining.

2. PCD End Mill Designs for CFRP

• 2–6 Flutes (fewer flutes for chip clearance, more for finishing).

• Sharp, Polished Edges to shear fibers cleanly.

• Up/Down-Cut Geometries to control surface finish.

• Compression Cutters (for laminated CFRP) to prevent delamination.

3. Best Practices

✔ Low Radial Engagement to reduce heat & tool wear.
✔ High RPM + Low Feed for best surface finish.
✔ Vacuum Extraction to remove hazardous carbon dust.
✔ Climb Milling preferred for smooth edges.

4. Top Applications

• Aerospace: Wing skins, fuselage panels.

• Automotive: Lightweight structural parts.

• Wind Energy: Turbine blades.

• Sporting Goods: Bicycle frames, rackets.
