What problems are likely to occur when machining aluminum alloys? How to solve them?

1. High cutting force, prone to deformation: The strength of aluminum alloy is relatively low. During cutting, it is prone to undergo plastic deformation, resulting in poor dimensional accuracy. 

Solution: Use sharp cutting tools, control cutting parameters (such as reducing feed rate and increasing cutting speed), and use coolant to reduce thermal deformation. 

2. Adhesion phenomenon: Aluminum alloy chips tend to adhere to the cutting tool, thereby affecting the quality of the processed surface. 

Solution: Select the appropriate cutting fluid, optimize the geometric angles of the cutting tools (such as increasing the rake angle), and use coated tools (such as TiN coated tools). 

3. High surface roughness requirements: Aluminum alloys are sensitive to surface quality, especially for seals or moving parts. 

Solution: Use diamond tools or ultra-hard material tools for precise processing and polishing.
