As mentioned in a previous blog article, metal burrs often occur in sheet metal operations and compromises the quality standard of a workpiece, so deburring is vital.

While the purpose of each deburring method is the same, there is a wide range to choose from. After discussing 3 common methods used within the industry in a previous blog article, we have discovered more techniques which we would like to explore.

6 Other Metal Deburring Methods

  1. Electromechanical Deburring

The combination of an electrical current with a salt or glycol solution has the ability to dissolve metal burrs. This precise and accurate technique is especially useful for hard-to-reach burrs or small workpieces.

  1. Electrolytic Deburring

This is a quick and efficient way of removing burrs from hidden and complex parts of the workpiece. Even though it is known for its accuracy, it will corrode the nearby area and cleaning alongside anti-rust treatment will need to be undertaken afterwards.

  1. Ultrasound Pressure

For burrs small enough you need a microscope to see them, ultrasonic deburring is the ideal technique. The instantaneous high pressure that it produces is capable of removing micro-burrs and other burrs from parts.

  1. Sub-Zero Temperatures

By using machined cooling, this enables the burr to tender quickly and it is then removed by non-abrasive spray with no dust or residue remaining. This technique is suitable for thick and small burrs on smaller workpieces.

  1. High Pressure Water Jet

The direct impact of the water has the pressure to remove burrs and edges on any workpiece. Even though it is quite an expensive piece of equipment, it also provides the purpose of cleaning too, so no debris is left.

  1. Grinding Deburring

For bulk small workpieces, deburring by using grinding methods, like sandblasting and roller, vibration and tumbling, is the best option. Even though it is better for large quantities, further cleaning is required to remove any residue left.

All of these deburring methods are using automatic machines which significantly increases efficiency in the metal fabrication process compared to choosing manual deburring techniques. Contact us today for more information or advice regarding your application.
