Description

Technical Field

[0001] The present invention relates to a mechanical manufacturing process, in particular to a surface polishing device and a polishing method for a cabinet, and belongs to the technical field of mechanical processing. Background Art

[0002] Surface polishing is a light-integrated processing method performed on a polishing machine or belt grinder using mechanical, chemical, or electrochemical processes. During processing, polishing paste is applied to a high-speed rotating, flexible polishing wheel or abrasive belt. The intense friction generates high temperatures, forming a very thin melt layer on the surface. This fills any microscopic irregularities, resulting in a shiny, mirror-like finish. Surface polishing is suitable for surface modification of coatings.

[0003] Cabinets are common outer shell components in mechanical equipment. In existing technologies, polishing cabinets generates dust. If the dust generated during processing is not cleaned in a timely manner, long-term inhalation will directly damage the human respiratory system and be detrimental to long-term operation. In addition, cabinets are cubic parts that need to be polished on all four sides. However, existing processing methods cannot polish multiple sides of the cabinet at once, thereby increasing the workload of operators. Summary of the Invention
