Carbon Fiber Milling Cutter

CFM650 Carbon Fiber Composite Material End Mill

16-flute Carbide End Mill

Ultrafine-grain carbideTiXSiN coating

The CFM650 series is a professional-grade end mill designed for efficient finishing and edge treatment of carbon fiber reinforced polymer (CFRP) parts. It features a 16-flute, 30° helix angle, diamond coating, and full-tooth corrugated cutting edge design, housed in a high-rigidity, ultra-fine-grained carbide substrate. Combining exceptional wear resistance, ultra-low cutting resistance, and excellent anti-delamination performance, it is an ideal choice for machining contours, grooves, and holes in carbon fiber parts for industries such as aerospace, new energy, and automotive. It provides an efficient and stable solution for machining your carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) parts, making it a good choice for various applications.

Engineering Features

Design details engineered for accuracy, tool life and process stability.

16-Flute Dense Corrugated Cutting Edge Structure

The ultra-dense corrugated cutting edge design subdivides the cutting edge into 16 segments, maximizing the dispersion of cutting force and effectively suppressing fiber delamination and tearing. It also significantly improves chip removal efficiency and prevents chip clogging.

Ultra-Fine Grain Carbide Substrate

Utilizing carbide with a grain size ≤0.8μm and a substrate hardness of HRC65, it combines high rigidity and toughness, offering 60% better chip resistance than ordinary tools.

Nano-Diamond Coating (DLC)

With a surface hardness of HV8000 and a coefficient of friction as low as 0.15, its wear resistance is 15-20 times that of ordinary carbide tools, significantly extending tool life.

30° Optimized Helix Angle

Enables progressive smooth entry, reducing impact on carbon fiber materials and lowering the risk of machining chatter marks, making it particularly suitable for edge finishing and deburring.

Large chip flute streamlined design

The chip flute space is 35% larger than that of ordinary end mills, improving chip removal efficiency by 40% and preventing chip clogging and secondary scratches on the workpiece.

Optimized coating adhesion strength

Utilizing plasma-assisted deposition technology, coating adhesion is improved by 30%, preventing coating peeling during high-speed cutting.

Carbon fiber composite material machining

Machining the contours and grooves of carbon fiber parts for aerospace and new energy vehicles.
