Design details engineered for accuracy, tool life and process stability.
A 2-3 μm thick TiN nanocoating is applied to the surface, achieving a hardness of HV2800 and a friction coefficient as low as 0.3. This effectively inhibits built-up edge formation, extending tool life by 2-2.5 times compared to uncoated tools.
The ball head precision is controlled within ±0.008 μm, and the surface roughness Ra ≤ 0.02 μm, enabling continuous curved surface machining without tool marks and reducing subsequent polishing steps.
Utilizing carbide with a grain size ≤ 0.8 μm and a substrate hardness of HRC65, this technology combines high hardness and toughness, improving chipping resistance by 35% compared to ordinary tools.
Utilizing streamlined chip flutes, chip removal efficiency is improved by 35%, preventing chip clogging in deep cavity or complex curved surface machining and reducing the risk of secondary scratches on the workpiece.
The cutter head diameter is 10% larger than that of ordinary ball end mills, significantly improving tool rigidity and eliminating runout during high-feed machining, ensuring consistency in surface depth and contour.
The coating withstands temperatures up to 800°C, maintaining excellent wear resistance even under high-speed dry or semi-dry cutting conditions, reducing the risk of coating peeling.
The cutting edge radius is precisely controlled at 0.012mm, balancing sharpness and wear resistance, adapting to the cutting needs of various materials, and reducing edge chipping.
Utilizing a DIN6535 standard straight shank, it is compatible with various clamping devices such as ER collets and hydraulic chucks, allowing for quick mounting on CNC machining centers and high-speed milling machines, improving tool change efficiency by 20%.
