CNC Machining 7075 aluminum
Machining 7075 aluminum typically involves the following steps:
Material Preparation: Ensure the 7075 aluminum stock is properly sized and clean. Verify its chemical composition and physical properties.
Tool Selection: Choose appropriate cutting tools such as carbide end mills or high-speed steel tools, which are capable of cutting aluminum at high speeds.
Machine Setup: Secure the aluminum stock properly on the milling machine or lathe. Verify the alignment and positioning.
Cutting Parameters: Determine the appropriate cutting speed, feed rate, and depth of cut based on the tool size, material, and desired cutting quality.
Cutting Operation: Begin the cutting process by gradually reducing the material. Apply cutting fluids, such as coolant or lubricant, to ensure heat dissipation and prevent chip buildup.
Surface Finish: Determine if the desired surface finish has been achieved. If necessary, use sandpaper or polishing tools to enhance the final appearance and smoothness.
Quality Inspection: Inspect the machined part for dimensional accuracy, surface finish, and any defects. Use measuring tools like calipers, micrometers, or coordinate measuring machines.
Post-processing: If required, perform additional processes such as deburring, cleaning, anodizing, or heat treatment to further enhance the part's properties or appearance.
It is important to note that machining 7075 aluminum can be challenging due to its high strength and toughness. Therefore, it is crucial to use proper cutting strategies and tools to minimize tool wear and achieve the desired results.
