CNC milling involves using a rotating cutting tool to remove material from the workpiece along multiple axes. The milling machine is programmed to move the cutting tool along a specific path to create the desired shape or feature on the aluminum block.
When milling aluminum 7075, there are a few considerations to keep in mind:
Material properties: Aluminum 7075 is known for its high strength and hardness. However, it also has poor machinability compared to other aluminum alloys. It tends to generate more heat during machining, leading to increased tool wear. Therefore, appropriate cutting parameters such as cutting speed, feed rate, and depth of cut should be selected to optimize the machining process.
Cutting tools: Carbide end mills are commonly used for milling aluminum 7075 due to their high hardness and heat resistance. They can withstand the higher cutting speeds and feeds required for efficient aluminum machining. Coatings such as TiAlN or TiCN can also be applied to the cutting tools to further enhance their performance and prolong tool life.
Coolant and chip removal: Adequate cooling and chip evacuation are crucial during the machining process. Aluminum 7075 has a tendency to produce long, stringy chips that can potentially cause issues. The use of coolants or lubricants helps dissipate heat and lubricate the cutting area, reducing tool wear and improving surface finish. Proper chip evacuation methods, such as using air blow or chip evacuation systems, should be employed to prevent chip buildup and ensure smooth machining.
Overall, CNC milling aluminum 7075 requires careful consideration of cutting parameters, selection of appropriate cutting tools, and effective cooling and chip evacuation strategies to achieve efficient and high-quality machining results.
