Burrs are simply defined as undesirable projections on a material and unfortunately, most manufacturers have to reduce, or more often totally eliminate them. As specifications for precision, cleanliness, and ease of assembly increase, existing deburring systems have improved, and a few new processes have been added. Most burrs are removed by chemical or physical means, but there are several other systems. Ice can be used as an abrasive in a deburring system. A stream of ice under air pressure of about 150 psi, creates particles that hit the part. This process works best with softer metals such as alloys of aluminum and brass. The process is environmentally friendly, plus, the melted ice helps clean the part's surface. Physical or chemical deburring methods may damage very small parts. That's why ultrasonic deburring is getting more attention. Earth-Chain USA offers a unique magnetic method for deburring smaller parts called the sPINner. The thermal-energy method uses intense heat for deburring and/or deflashing.
