How To Effectively Debur Sheet Metal Parts

Burr - People who have struggled with the sheet metal parts industry must be familiar with it. In the processing of sheet metal parts, it is ubiquitous. No matter how advanced and sophisticated equipment you use, it will be born in the product. The so-called burr is mainly a kind of extra iron scrap generated by the plastic deformation of the material and processed at the edge of the processed material, especially the material with good ductility or toughness, especially the burr, and the burr problem is the metal plate part. One of the challenges that the processing industry has so far failed to solve.
 The types of burrs in the processing of sheet metal parts mainly include flash burrs, sharp burrs, splashes and the like, and a protruding excess of the remaining metal sheet parts that do not meet the design requirements of the product. For this problem, there is no effective method to eliminate it in the production process so far, so to ensure the design requirements of the products, engineers only have to work on the removal of the latter, so far different products are different. There are many methods and equipment for removing burrs.
 In general, the method of removing burrs can be divided into four categories.
 The coarse grade (hard contact) belongs to this category of cutting, grinding, boring and scrapping.
 Ordinary grade (soft touch): This category is abrasive belt grinding, grinding, elastic grinding and polishing.
 Precision grades (flexible contact): This category includes processing, electrochemical machining, electrolytic grinding, and rolling.
 Ultra-precision (precise contact): This type of deburring methods, such as abrasive flow deburring, magnetic grinding deburring, electrolytic deburring, thermal deburring, and dense radium ultrasonic deburring, etc. Part processing accuracy.
 When we choose the deburring method, we should consider various factors, such as the material properties of the part, the shape of the part, the size and precision of the part, especially the changes of surface roughness, dimensional tolerance, deformation, and residual stress.
