Design details engineered for accuracy, tool life and process stability.
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.
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.
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.
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.
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.
Utilizing plasma-assisted deposition technology, coating adhesion is improved by 30%, preventing coating peeling during high-speed cutting.
Machining the contours and grooves of carbon fiber parts for aerospace and new energy vehicles.
