Material Properties: Aluminum alloys are lightweight, corrosion-resistant, have good thermal and electrical conductivity, and are easy to machine. They are widely used in industries such as aerospace, automotive, and electronics. Common grades include 6061, 7075, and 2024, which are selected based on specific strength and performance requirements.
Machinability: Aluminum alloys are easy to cut and have excellent machinability. However, due to their softer nature, burrs and machining marks can easily form during the process. Selecting the appropriate cutting tools and parameters is crucial for improving machining efficiency and surface finish quality.
Cooling and Lubrication: During aluminum alloy machining, using proper coolants or lubricants helps reduce cutting heat, extend tool life, minimize surface oxidation, and improve machining accuracy.
Tolerance Control: The machining tolerance for aluminum alloy parts can generally be maintained within a narrow range, depending on the part’s application and design requirements. Common tolerance ranges from ±0.05mm to ±0.2mm, varying based on the machining equipment and process.
Surface Treatment: After machining, aluminum alloy parts can undergo various surface treatments such as anodizing, electroplating, or painting to enhance surface hardness, corrosion resistance, or achieve a specific aesthetic effect. For instance, anodizing increases corrosion resistance and allows for a variety of color finishes.
