What are the polishing methods of motor housing aluminum extrusions?

Update time : 2023-03-30 19:31:29

Motor housing aluminum extrusions are often inseparable from polishing if they want to achieve smooth or mirror effect. Its grinding refers to the use of mechanical, chemical or electrochemical action, reduce the roughness of the workpiece surface, make the surface bright and smooth processing method. As there are many motor housing aluminum extrusions oxidized and tarnished every year, it is through polishing that motor housing aluminum extrusions can restore the luster of the past. Then do you know what are the methods of polishing motor housing aluminum extrusions?

Motor housing aluminum extrusions polishing method:

1. Mechanical polishing: mainly with polishing wax polishing wheel processing aluminum alloy shell surface, can reduce the roughness of aluminum alloy shell surface, make the surface smooth, bright or mirror effect, can effectively repair aluminum alloy shell surface scratches and scratches.

2. Electrolytic polishing: electrochemical polishing uses chemical action to take electrolytic polishing as anode, insoluble metal as cathode immersed in electrolytic cell, through direct current to dissolve anodic alumina, so that aluminum skin lose luster.

3. Chemical polishing: chemical grinding can be used as a pretreatment process for protective decorative electroplating, or as a pretreatment process for chemical film formation such as phosphating pholan. If the paint before dipping antirust passivating water solution, can eliminate the surface of aluminum profile shell alumina.

4. Ultrasonic polishing: Ultrasonic grinding is a processing method of grinding brittle and hard materials with abrasive suspension using ultrasonic vibration of tool section. Put the workpiece into the abrasive suspension, into the ultrasonic field, through the vibration of ultrasonic, abrasive grinding on the surface of the workpiece.
