When we CNC machine metal parts, there are often scratches on the surface. What is the reason for this? What are the solutions? Today, Shenzhen Noble Intelligent Manufacturing Technology Co., Ltd. will talk about the causes and solutions of scratches on the surface of aluminum profiles during processing.
CNC processing of aluminum alloy parts
Main causes of aluminum profile 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 profile surface will be scratched;
2. Scratch caused by dragging on the swing bed;
3. Loss caused by friction or extrusion between profiles during transportation.
What are the solutions
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.
