Internal Thermal Deburring


Internal deburring is the process of removing excess, sharp material called burrs from the inside of machined parts. For parts with internal passages, internal thermal deburring is an essential service for improving the highest performance level.

Arrow Cryogenics offers internal thermal deburring services for a range of industrial applications.

Internal Deburring Improves Performance and Quality of Machined Parts

Internal burrs impact the overall performance and quality of a part, changing the way liquid or gas can flow through the component. Depending on the application, burrs can also cause critical damage, like contamination in food processing applications and other undesired skin and tissue damage in medical applications.

Using internal deburring removes sharp burrs that could lead to hazardous situations, leaving behind smooth parts. Thermal deburring (TEM) uses a mixture of gasses ignited inside a deburring chamber, creating extremely high temperatures. During this process, the internal burrs burn off from the part, leaving a smoother surface inside.

Benefits of Internal Thermal Deburring:

  • Quick, effective burr removal
  • Consistent and repeatable process
  • Reduces or Eliminates the need for a follow-up inspection
  • Works on a range of materials
  • Requires little to know changeover time
