1. Choose a professional saw blade because the hardness of industrial aluminum profiles is not as high as steel, making sawing relatively easy. However, due to the insufficient hardness, it is easy to stick to aluminum, so the blade must be sharp and replaced after a period of use.

2. Choose the appropriate lubricating oil If cutting directly without lubricating oil, there will be many burrs on the cutting surface of aluminum profiles, which are difficult to clean and the saw blade is very damaged.

3. Most industrial aluminum profiles are cut at right angles, and some require cutting at an oblique angle, with a 45 degree angle being more common When cutting the angle, it is important to control the angle and it is best to use a CNC sawing machine.
