POLISHING

 

Polishing is divided into precision polishing and decorative polishing. Improve precision polishing: generally, when the dimensional accuracy and roughness of metal surface are very high, use grinder to reduce surface roughness and improve precision. Decorative polishing: for parts with smooth or specular gloss requirements on the appearance surface, after the processing size is in place, polish the part surface to the required bright effect through canvas wheel, felt wheel, leather and other tools. Usually, decorative polishing needs to be polished with polishing agents such as polishing paint. Special industries, such as watch parts, usually cannot adopt automatic polishing, but must be polished manually, and qualified products can be made through repeated polishing, grinding and inspection.

 

How Do You Polish Surfaces?

Surface polishing includes mechanical surface polishing and artificial surface polishing:

 

Mechanical polishing. A polishing machine is a kind of mechanical equipment that the integrated motor drives up, down, left and right groups of automatically adjustable grinding wheels or abrasive belts to polish the workpiece surface of the machine. Through high-speed friction, the rust layer and fine defects on the workpiece surface are polished smooth. Mechanical polishing is suitable for surface polishing of large quantities of workpieces and can be part of the assembly line process.

 

Hand polishing. Manual polishing is generally used to polish the contact surface (appearance surface) of clocks, ornaments, abrasives, and machine tools that need mirror polishing. The demand for workpiece can be realized through manual experience and customized polishing equipment and polishing media.

 

What Is Polishing Used For?

Polishing is mainly used in the following aspects:

 

01

Derusting and degreasing of raw materials.

 

02

Requirements for external surface polishing of clocks and ornaments.

 

03

Contact surface, sliding surface, and fluid surface of mold and machine tool industry.
