The high-precision 90 °1mm coated hard alloy chamfering tool launched by AMG is designed for fine chamfering of electronic components and 3C product parts, suitable for application scenarios with high requirements for surface smoothness and processing stability.

This product uses high-quality hard alloy substrate and advanced PVD coating technology, which has excellent wear resistance, thermal stability, and low friction performance, and can maintain long-term stable performance in high-speed and high-precision processing. Suitable for chamfering electronic components such as aluminum, copper, stainless steel, and commonly used materials for 3C product casings, effectively improving processing efficiency and surface quality

Applications:

• Precision Electronics: Chamfering of PCB edge connectors, aluminum heat sink edges, and fine grooves requiring burr-free surfaces.

• 3C Parts Machining: Ideal for mobile phone frames, tablet casings, and laptop components that require consistent 90° chamfers with high surface quality.

• Watch and Medical Devices: Suitable for deburring and edge finishing of small stainless steel and titanium parts.

Working Principle

The AMG 90° carbide chamfering tool operates through high-speed rotation on CNC milling or chamfering machines,integrate the workpiece edge to create consistent 90° chamfers with a width of 1mm. The PVD coating minimizes friction and heat generation, preventing material sticking and edge burring during high-speed operations. The sharp cutting edges ensure precision removal of material while keep a smooth, clean chamfer with high dimensional accuracy across many workpieces.

Advantages:

• High Stability: AMG’s manufacturing process ensures tool concentricity and balance, reducing vibration and deflection during chamfering.

• Fine Surface Finish: Achieves Ra 0.2-0.4 μm finishes, eliminating post-processing in many applications.

• Long Tool Life: PVD coatings enhance wear and oxidation resistance, extending tool life in high-speed cutting conditions.

• Precision Edge Control: Maintains consistent 90° angles and 1mm chamfer width for precise component finishing.

• Reduced Burrs: Produces clean edges, reducing the need for secondary deburring operations.

FAQ:

1. What materials can the tool machine?
   It is suitable for aluminum alloys, copper, brass, stainless steel, and titanium commonly used in electronics and 3C manufacturing.

2. Can the chamfer width be customized?
   Yes, AMG can customize the chamfer width to 0.5mm, 1.5mm, 2mm, or other sizes based on customer requirements.

3. What cutting speeds are recommended?
   For aluminum, 200-600 m/min; for stainless steel, 80-150 m/min, with appropriate feed rates based on the material and chamfer size.

4. What is the typical tool life?
   Under proper cutting conditions, tool life can exceed 30% longer than uncoated or lower-grade carbide chamfering tools.
