When we are processing metal parts with CNC, the surface is often scratched. What is the cause of aluminum alloy? What are the solutions? Today, Shenzhen Noble Smart Manufacturing Co., Ltd. will talk about the causes and solutions of scratches on the aluminum alloy surface.
Processing of aluminum alloy parts
1、 Main causes of aluminum alloy surface damage:
1. There are sundries attached to the ingot surface or the ingot composition is low, so there will be a lot of segregation and floats on the ingot surface, which will lead to a certain amount of hard metal particles in the ingot when the ingot has never been homogenized or the homogenization treatment effect is not good. It is precisely because of these reasons that the aluminum alloy surface will be scratched;
2. Scratch caused by dragging on the swing bed;
3. Loss caused by friction or extrusion between profiles during transportation.

2、 Solution to scratch on aluminum alloy surface:
1. Strengthen the control of ingot quality;
2. Properly place the profiles in the material frame to avoid mutual friction;
3. Handle with care during CNC processing and production to avoid dragging or turning profiles at will.
