Tumbling & Deburring
Many times, in the metal cutting process, parts are left with small raised edges that can be very sharp. These small pieces of metal that remain attached to the metal parts are known as burrs. In order to get rid of these small, stray pieces of metal that can be dangerous when handling metal parts, we use a deburring process.
The key to creating a metal part without burrs is to not make any burrs in the cutting process, but this is not always possible. It is inevitable that when you are cutting metal, there will be some minor imperfections in the material that cause burrs. Because of this, we must use deburring machines in our metal fabrication process to make sure that we are providing the best quality products for our customers.
It would be very time-consuming and laborious to remove metal burrs individually, by hand. That is why we use a barrel tumbler to deburr many small parts at once. Barrel tumbling is excellent at rounding off corners and removing any sharp burrs on parts that have heavy radiuses. Different speeds and amplitudes of vibration are used when deburring different parts, but in general: High speeds and large amplitudes can get the job done by rolling over burrs and mushroom sharp edges.
When using the process of vibratory deburring, it can be compared to that of a filing action. As upward, angular force is applied, metal parts and media are rubbed together creating a cutting action. A vibratory tumbler applies a force 5 to 10 times greater than that of a barrel tumbling machine. This results in a much shorter cycle time as the vibratory tumbler is able to cut the entire load with one pulse. Vibratory deburring can be used on fragile parts because there are no unequal forces acting on the parts.
Inside the Machines
Both Barrel tumbling and vibratory deburring use some form of media to create soft, clean edges on metal parts. The media in our deburring machines may consist of stone, ceramic, or plastic beads. Water is added to the machines to wash away dirt and carry the media. When necessary, chemicals are used to improve the quality of the finished product.
