The AlTiSiN coated four edge inner R milling cutter launched by AMG is designed specifically for high-speed milling applications in CNC machining centers, capable of accurately machining the inner R angle and complex surface structures of mold cavities.

The cutting tool maintains excellent stability during high-speed rotation and is suitable for surface machining of various high-precision molds and precision parts.

• Mold Surface Machining: Ideal for plastic injection molds, die-casting molds, and stamping dies with complex curved surfaces
• Aerospace and Automotive Components: Suitable for machining lightweight alloys and high-strength materials with complex contours
• Medical Device Manufacturing: Machining titanium or stainless steel curved parts requiring high surface quality
• Precision Mechanical Parts: Used for milling detailed curved features in precision machinery

The coated four blade internal R milling cutter achieves precision milling of mold cavities, rounded corners, and complex surfaces through high-speed rotation of the CNC machining center. The front of the tool is designed with an inner R-arc structure, which can accurately process the inner rounded corners and curved transition areas in the mold.

The cutting tool adopts four edge cutting structure, which ensures more balanced cutting force and effectively reduces vibration and tool lines during the machining process, ensuring a smooth and delicate machining surface. At the same time, the four cutting edges work together to significantly improve chip removal efficiency, making it particularly suitable for continuous and high-speed machining.
