What is the correct way to cut Aluminium?

01 Jun, 2021

1. Choose a professional saw blade, because the hardness of industrial aluminum profile is not as big as that of steel, it is relatively easy to saw, but because the hardness is not large enough, it is easy to stick to aluminum, so the blade must be sharp, and it must be replaced after a period of use.

2. Choose a suitable lubricant. If you do not use lubricant for dry cutting, the cut surface of the aluminum profile will have a lot of burrs, which is difficult to clean and will damage the saw blade.

 

3. Most aluminum profiles are cut at right angles, and some require bevel cuts, 45 angles are more common. When cutting the bevel, the angle must be controlled well, and it is best to use a CNC sawing machine to saw.

 

Let's take a look at what steps need to be cut after industrial aluminum extrusion is produced?

1. The aluminum profile must be sawed after extrusion. At this time, it is rough cut. The length is generally controlled at 6 meters or more and 7 meters or less. Too long industrial aluminum profiles are inconvenient to enter the aging furnace for aging and oxidation in the oxidation tank.

 

2. If the customer buys the material and goes back to sawing and processing, we need to saw off the oxidation electrodes at both ends after the anodized packaging is finished. The length of the profile is generally controlled at 6.02 meters.

 

3. If you purchase semi-finished products for processing, we have to transfer to the processing workshop to perform fine cutting according to the actual size used. The size tolerance of fine cutting is generally controlled within ±0.2mm. If there is a need for further processing, further processing (punching, tapping, milling, etc.) is required.
