The Solution of Abnormal Wear of Abrasive Belt
"Clogging", "Metal chips cover the abrasive grain" and "Blunt" are common abnormal wear phenomena of abrasive belt.
"Clogging" occurs when the abrasive gap is quickly covered and filled with chips before the abrasive cutting edge is completely blunted, thus depriving the abrasive belt of its cutting ability. There are many reasons for clogging, mostly due to improper use, processing materials and sand belt selection, etc.
"Metal chips cover the abrasive grain" occurs when the metal chips cover the cutting edge of the abrasive grain. At this time, the surface of the belt becomes smooth. Covering the abrasive grain mainly occurs in metal materials with high strength, especially hard and tough materials.
"Blunt" is because the abrasive cutting edge becomes blunt due to wear. The normal blunt is the end of the belt life, obviously we refer to the "blunt" here is not exhausted when the abrasive grain is not exhausted. Improper selection or use of sand belt is the main cause of this situation.
So, how to slove the problems and improve the efficiency and service life of abrasives belt? Here are some tips.
First, choose abrasive belt with excellent self-sharpness. This can effectively solve the problem of
"metal chips cover the abrasive grain". Good self-sharpening and enough grinding pressure is the key to improve grinding efficiency.
Second, choose the proper abrasive belt. Most problems are caused by improper product selection. To avoid "blunt", make sure the sanding belt used is the right one for the job. If you feel the polishing effect is not what you want, it's very likely you are using the wrong product.
Finally, choose the sanding belt with open abrasive. This is the solution to avoid clogging. Coarse-grained sand belt can also be adopted under the condition of satisfying the roughness requirement.
Yihong can provide you sanding belt with different abrasive and high quality.
