Grinding/polishing is a kind of surface treatment technology, the purpose is to remove the burr of products to get the smooth surface for finish processing. Sanding dust produced by grinding / polishing process will cause pulmonary and respiratory tract and nasal cavity hurt. Sparks generated during the operation can irritate the skin and cause burns. Especially the high speed particles generated in the process will make great damage to human. Long-term inhalation will lead to life-threatening. Industrial robot grinding / polishing applications not only ensure rigidity and accuracy, but also can carry out flexible grinding/polishing process trajectory programming.
