1. Choose a saw blade, because the hardness of industrial aluminum profiles is not as good as steel and it is easier to cut. However, because the hardness is not high enough, aluminum is easy to stick to, so the saw blade must be sharp and needs to be replaced after being used for a period of time.

2. Choose the appropriate lubricating oil. If you do not use lubricating oil for dry cutting, there will be many burrs on the cutting surface of the aluminum profile, which is difficult to handle and will damage the saw blade.

3. Most industrial aluminum profiles are cut at right angles, but some require bevel cutting. A 45-degree angle is common, and the angle must be controlled when cutting bevels. Sawing with a CNC saw.
