• High Performance Material : AYCHOLIZ end mill is made from solid tungsten carbide, which gives it exceptional toughness, durability, and machinability.
• Zirconium Nitride Coating : The Zirconium Nitride (ZrN) +Titanium aluminum boron nitride (AlTiBN) coatings ensure stability even at high temperatures and provide superior heat resistance compared to TiAlN, TiN, or TiCN coatings.
• Distinctive Unequal Helix Design : Unequal helix design refers to the different cutting edges of the milling cutter having different spiral angles. This is an innovative way designed to reduce the resonance effect.
• Unequal Helix End Mill Advantages : ✅Better vibration resistance✅More even distribution of cutting force✅Improved surface quality✅Heat dispersion: The heat during cutting can be distributed more evenly, which helps to avoid overheating of the tool.
• Aoolication : Unequal helix milling cutters are generally suitable for hard materials (such as high-hardness steel, stainless steel) or machining scenarios with high requirements for surface finish. Commonly used in high-speed, high-precision machining, especially for precision parts that are sensitive to vibration.
