The causes and treatment methods of surface indentations on precision stainless steel strips may include the following aspects:
Mechanical scratches during processing: It may be caused by mechanical contact or friction during processing, such as surface wear generated during cutting, bending, stamping, etc.
Treatment method: The occurrence of mechanical scratches can be reduced by adjusting processing parameters, optimizing the process flow, and selecting appropriate tools and molds.
Tool surface defects: Defects or foreign matter on the surface of the machining tool may cause indentations to be left on the surface of the stainless steel strip during machining.
Treatment method: Regularly inspect and maintain processing tools to ensure that their surfaces are smooth and defect-free, and replace seriously worn tools in a timely manner.
Material surface defects: The stainless steel belt itself may have some surface defects, such as oxide scale and uneven unevenness. These defects are easily further aggravated to form indentations during the processing process.
Treatment method: Choose good quality stainless steel strips, and thoroughly clean and treat the material before processing to ensure a smooth and smooth surface.
Improper control of processing temperature and pressure: Improper control of temperature or pressure during processing may cause local overheating or excessive pressure on the material, forming surface indentations.
Processing method: Strictly control the temperature and pressure during processing to ensure processing within appropriate parameter ranges and avoid excessive heat treatment or excessive pressure.
External environmental factors: such as dust, foreign matter, etc. may adhere to the surface of the stainless steel belt, causing indentations.
Treatment method: Keep the processing environment clean, prevent dust and foreign matter from entering the processing area, and use clean processing tools and equipment.
