Definition and process of cryogenic deburring:
Cryogenic deburring involves the use of liquid nitrogen or carbon dioxide to cool the workpieces to extremely low temperatures. The process consists of several steps: preparing the workpieces, placing them in the deburring machine, cooling with cryogens, rinsing off the residue and drying the workpieces. The cooling step allows the material to become brittle, which makes it easier to remove the burrs. After cooling, the workpieces are treated with suitable methods, such as shaking, brushing or rinsing, to remove the loosened burrs. Finally, the workpieces are dried and are ready for further use.
Advantages and applications of cryogenic deburring:
This innovative deburring process offers a variety of benefits. Firstly, it enables precise removal of burrs and sharp edges without compromising the surface integrity of the workpiece. This avoids additional post-processing steps and increases productivity. Secondly, cryogenic deburring can also reach complex geometries and hard-to-reach areas that are difficult to treat with conventional deburring methods. This makes it an ideal solution for the automotive, aerospace, medical and electronics industries. Another advantage of cryogenic deburring is its environmentally friendly nature. Conventional deburring processes often use harmful chemicals or abrasive methods. In contrast to these, cryogenic deburring works with pure liquid nitrogen or carbon dioxide, which simply evaporate and do not pollute the environment. The applications of cryogenic deburring are diverse. It is often used in the processing of plastic components for vehicles, medical devices, electronic components and precision parts. It has also proven to be extremely useful in deburring 3D printed parts where a smooth and burr-free surface finish is required.
