During CNC machining of aluminum, the main materials commonly used for cutting tools and fixtures include high-speed steel, cemented carbide, end mills, etc; The specific types and materials of cutters and fixtures are selected based on the properties of the aluminum alloy material being processed and the geometric shape of the workpiece. The materials used in some typical aluminum CNC machining are detailed as follows:

Tool material: cobalt based cemented carbide, abrasive steel, high-speed steel, etc.

Clamp materials with high strength, good rigidity, and not easy to deform: cast iron, steel, aluminum alloy, etc.

Necessary accessories for efficient metal processing: Milling heads and drill bits are generally made of hard alloy or sharp steel.

In summary, when selecting the appropriate material, it is necessary to consider the processing efficiency and cost to ultimately arrive at the optimal solution.
