Abstract

The invention relates to the technical field of metal machining, in particular to a metal aging process and metal surface polishing equipment. The metal aging process comprises the steps of 1, carrying out electrolytic degreasing treatment on a metal workpiece in degreasing liquid; 2, carrying out acid treatment on the metal workpiece treated in the step 1 in an acid salt solution; 3, carrying outsurface chemical deposition treatment on the metal workpiece treated in the step 2 in an electrochemical deposition gold solution, so that a black ruthenium layer is electroplated on the surface of the metal workpiece; and 4, polishing the surface of the metal workpiece treated in the step 3 by using the metal surface polishing equipment to polish away part of black ruthenium layer on the surfaceof the metal workpiece, so that the residual black ruthenium makes the surface of the metal workpiece appear as an aging effect. The metal surface polishing equipment comprises a rack, wherein a material tank, a vibrating device, a rotation driving device and an ultrasonic device are arranged on the rack. According to the metal aging process, the process steps are simple, and the surface of the machined metal product can present a retro visual effect and meet the requirements of customers.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a metal aging process and metal surface grinding equipment. Background technique [0002] Precious metals mainly refer to gold, silver and platinum group metals, such as ruthenium, rhodium, palladium, osmium, iridium, platinum and other metal elements. Most precious metals have beautiful color and strong chemical stability. Under normal conditions, they are not easy to chemically react with other chemical substances. They are often used to make jewelry, accessories, etc. The surface of the jewelry and accessories made has a bright metallic color. . However, due to market demand, the appearance of some jewelry or accessories needs to present a visual effect of age or vicissitudes, but the effect produced by the existing old-fashioned process is not realistic enough and does not meet customer requirements. Contents of the invention [0003] In order to overcome the def...
