Design details engineered for accuracy, tool life and process stability.
Utilizing cemented carbide with a grain size ≤0.8μm and a substrate hardness of HRC65, it combines high rigidity and toughness, offering 50% better resistance to chipping compared to ordinary tools.
Symmetrically distributed four flutes ensure uniform distribution of cutting force, improving vibration suppression by 40% and achieving a surface finish of Ra0.4μm or less, reducing fiber delamination and burrs.
Surface hardness HV8000, a friction coefficient as low as 0.15, and wear resistance 10-15 times that of ordinary cemented carbide tools, significantly extending tool life.
Enables progressive smooth entry, reducing impact on carbon fiber materials, effectively suppressing fiber delamination and tearing, and significantly improving machining quality.
The chip flute space is 35% larger than that of ordinary end mills, improving chip removal efficiency by 40%, avoiding chip clogging and secondary scratches on the workpiece.
Plasma-assisted deposition technology improves coating adhesion by 30%, preventing coating peeling during high-speed cutting.
Machining of carbon fiber parts contours and grooves for aerospace and new energy vehicles.
