Thermal deburring utilizes an oxygen-rich, fuel-filled atmosphere in a small chamber to ignite intense temperatures for around 20 milliseconds. This cleaning process vaporizes any burrs that are attached to a metal or plastic workpiece, thereby leaving behind a clean part that works at peak efficiency. The consistency of thermal deburring saves time and money by removing these imperfections quickly and efficiently inside an automated machine. JAYCO Cleaning Technologies explains some of the physical limitations of thermal deburring, even though it’s a highly advanced and efficient method of removing burrs.
Thermal deburring chambers are relatively small because they operate under extreme temperatures and pressures. Some of the largest thermal deburring chambers measure 400 millimeters (15.7 inches) in diameter by 600 millimeters (23.6 inches) high for cylindrical components. This process may not work for items much larger than that, depending on what type of machine you have.
Thermal deburring works mostly for metal and thermoplastic workpieces. Even some metals may not withstand the high heat of this process. Copper, gold, lead, platinum, and vanadium are incredibly malleable. They are also susceptible to high heat, which could make them melt in a thermal chamber.
The size of burrs is a factor for high-heat removal. Small burrs are almost microscopic, at 0.25 millimeters or less in length, while larger burrs are greater than 0.28 millimeters in length. Burr thickness also determines how quickly they vaporize. You may need two thermal deburring procedures to remove all burrs. Microscopic burrs almost certainly are cleaned away with high, intense heat. However, burrs that are nearly as thick as your workpiece may not disappear at all.
Your workpiece must endure intense heat and pressure in the deburring chamber, and very thin walls don’t work for this process. In general, the thickness of the workpiece must be at least 0.03 inches (0.76 millimeters) to withstand thermal deburring. Otherwise, the workpiece itself might melt or oxidize along with the burrs. Your piece could also become structurally unsound or unstable if you have walls less than 0.03 inches thick.
