Thermal Deburring (TEM)

Our high-heat thermal deburring solves the problem of deburring parts with recessed or impossible-to-reach areas, in addition to burning off burrs on external surfaces.

Thermal deburring effectively cleans boring remnants and removes trapped machining particulates. Meanwhile, thermal deflashing is proficient in eliminating flash from various materials, including cast aluminum, zinc, steel, stainless steel, brass, and other metals, whether ferrous or non-ferrous.

The Heat is On – Briefly

The deburring happens in a brief burst of heat, reaching temperatures of 5430°F (3000°C) for about 20 milliseconds. That’s enough time for deburring without affecting part dimensions or metallurgy.

Benefits of Thermal Deburring

Less costly than hand deburring
Fast and efficient for removing small and large burrs
Does not alter part surface finish
Geometry thread forms not affected
Higher level of consistency over manual deburring
Eliminates burrs in inaccessible internal areas

FAQs

Thermal deburring and cryogenic deflashing are opposite sides of the deburring spectrum. Thermal deburring uses a high burst of heat for milliseconds to burn away burrs. Cryogenic deflashing uses sub-zero temperatures combined with a tumbling process to deburr and deflash parts.

Temperatures may reach 5430°F (3000°C) in a thermal deburring chamber, lasting milliseconds.

No. Thermal deburring does not alter the surface or geometry of the parts or thread forms.

Thermal deburring offers several benefits including:
