Deburring is an important part of the metal finishing process. It’s the removal of small extraneous metal pieces curling or sticking out of a part. Other metal finishing processes further smooth out imperfections on a part’s surface, such as machining scaling, marks, or pitting.

 

Grinding, Sanding, Lapping, and Polishing

 

Despite the technology that is available today, manual processing of metal parts is still common in many manufacturing facilities. Even parts that are machined on the most sophisticated CNC equipment are finished through the utilization of hand, air, and ultrasonic powered tools.

 

Abrasive Blasting

 

This is the process of directing an abrasive material in the form of solid particles through a nozzle and pushing it out with compressed air against the part’s surface. There are different materials that can be utilized in this process, all depending on the type of metal being finished and the desired effect.

 

Sand is commonly utilized since it’s inexpensive and able to texture and clean large metal surfaces. Other examples of abrasive blasting materials include dry ice, glass beads, crushed walnut shells, and baking soda.

 

Mass Finishing

 

This is a timed batch process that involves the utilization of abrasive materials and a vibrating or rotating process vessel to simultaneously deburr and finish many machined parts.
