Cryogenic Deburring


A raised edge or rough edge of excess material created from a machining process is called a burr. A burr is the result of performing a machining operation such as grinding, milling, drilling or turning. Burrs are created on plastic, die cast, and metal parts.

Removing this burr is called deburring. The cryogenic deburring process involves placing the parts in a deburring machine, then using liquid nitrogen to cool the parts to a low temperature. Once the burrs freeze, parts are ran through a machine with media to remove the burrs.

Cryogenics for deburring allows for safe, clean removal of burrs without damaging the surface or altering the geometry of a part. It is highly effective and can be used on a broad range of plastic, rubber and die cast materials.  Cryogenic deburring is used to finish a variety of machined parts such as:

  • Medical implants, surgical tools and devices
  • O-rings & gaskets
  • Grommets and flexible boots
  • Electronic connectors, switches, and bobbins
  • Manifolds and valve blocks
  • Gears, washers and fittings

Arrow Cryogenics has offered cryogenic deburring services since 1983 and works with a various industries including aerospace, medical, and several others. Our expertise, along with a wide variety of cryogenic deburring machines, has allowed us to master the art of turning your precision machined components into high quality, finished parts.

Cryogenic Deburring Improves the Look and Quality of Components

Cryogenic deburring machines can process anywhere from several to a few hundred pieces at once, saving a significant amount of time over hand deburring methods. Since the entire process is computer-controlled, temperatures can be programmed for the specific material being finished. Cryogenic deburring also makes it easier to remove internal and microscopic burrs that would be extremely difficult and time-consuming to remove manually.

Deburring plastic components increases their safety, quality and functionality. The cryogenic deburring process is much more economical than labor intensive hand deburring and provides a higher level of repeatability.

Additional benefits of using cryogenics for deburring include:

  • Non-abrasive method of removing burrs
  • Computer-controlled for a high level of consistency and accuracy
  • Efficient and economical
  • Leaves little to no dust or residue on parts
  • Ideal for large and small parts
  • Maintains part geometry and critical tolerances
