Tips for Procurement and Considerations when Purchasing from aluminium machinability
## Aluminum Procurement Tips for Machinability:
1. Alloy Selection: Not all aluminum alloys are created equal. Consider 6061 for general applications, 7075 for high strength, and 2017 for good machinability with moderate strength.
2. Temper: Temper defines the alloy’s hardness and workability. For ease of machining, choose annealed or O temper.
3. Material Thickness: Thicker material can lead to more heat generation and increased tool wear during machining. Consider thinner stock if possible for easier processing.
4. Material Condition: Ensure the aluminum is free of surface defects, inclusions, and impurities to avoid tool damage and inconsistent results.
5. Supplier Choice: Partner with a reliable supplier who offers consistent quality and can provide technical support on alloy selection and machinability.
6. Tooling & Cutting Parameters: Consult a tooling specialist to select the right cutting tools, speeds, feeds, and depths of cut for optimal machining performance and tool life.
7. Machining Process: Consider the machining process and choose an appropriate machining strategy to optimize efficiency and minimize waste.
By applying these tips and considering these factors, you can make informed purchasing decisions that lead to successful and cost-effective aluminum machining operations.
