Have you heard of thermal deburring? Want to know what it does? You came to the right place! I will address this unique process, highlighting why I think it should be the next great addition to your operations.

As the name suggests, thermal deburring is a technology deployed to remove the burrs off machined parts crafted in a production process. Castings, manifold blocks, and basically any piece with burrs can benefit from thermal deburring to exhibit a quality finish in those impossible-to-reach areas of the part. The process suits the metallic and thermoplastic materials used in the automotive, aerospace, energy, medical, and power industries.

How does thermal deburring occur? A mixture of fuel gas and oxygen combusts evenly in a pressurized chamber. Inside the confined space, temperatures can go as high as 6,400°F. Subsequently, the reaction forwards the oxidation of the burrs left behind in the machined components. 

The entire process is automatic, with the burrs’ ignition taking 20 milliseconds or so! 

Sometimes, after the ignition, an oxide film remains. When that happens, following a washing procedure applies. The type of cleaning agent selected varies, depending on the element to remove. It’s important to mention the deburring process also helps with flashing and hidden contaminants. Pretty awesome, right?

Overall, there are several advantages to integrating thermal deburring in a manufacturing plant. For instance, it can: 

  •  Save time and labor: the process only takes 30 to 35 seconds per part.
  • Optimize the cleaning process of the piece: automated, high-tech machines and a control panel receive inputs from the operator based on the size and material of the workpiece. 
  • Achieve higher reliability and consistency than conventional methods: thermal deburring machines use exacting methods to clean workpieces, which increases the degrees of quality control in entire batches.
  • Enhance worker safety: every aspect of the deburring process is secure, reducing the chances of accidents and human errors. If the combustion process concerns you, rest easy! The chamber is fully sealed and insulated to the exterior. Gas venting happens through a pipe that goes to the roof.
