Abstract
A burr trimming device includes a removing assembly and a directed spraying assembly disposed on a carrier, wherein the directed spraying assembly has a nozzle facing the removing assembly. The directed spraying assembly rapidly freezes objects such as burrs and then the removing assembly removes the hardened objects by coming into rigid contact therewith, thereby ensuring complete removal of the fine flexible burrs.
