Vibratory Finishing Machine are used for surface treatment of various hardware, commonly known as grinding and polishing. The third vibration principle is used to treat the surface of the product to achieve the effect of lubrication, smoothness and brightness, but how to control the brightness of grinding and polishing?
Many customers will encounter the appearance of blackening or the brightness does not meet the expected requirements in the polished products, and the following points should be paid attention to. 1.

For example, if the product has no dead spots, choose a terrazzo or polished stone. For products with dead corners, choose an inclined cylindrical or triangular grinding stone or polishing stone, and then choose the size of the grinding stone or polishing stone according to the size (ie size) of the dead corner; 3. Before grinding and polishing, oily products should be cleaned.
Improvement measures for blackening after polishing by the vibrating grinder: (1) Grinding aids with oil removal function can be customized according to needs; (2) Before grinding and polishing, use detergent to clean the surface oil of the product; (3) If there is any oil in the grinding tank of the equipment Residual oil, it is recommended to clean the surface oil of the machine during the cleaning time before grinding and polishing. 4.
