Thermal Deburring
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.
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:
- Less costly and time-consuming than hand deburring
- Fast and effective removal of small or large burrs
- Does not damage part surface or affect part geometry and threads
- Higher level of consistency than manual deburring methods
Thermal deburring is conducive for all types of metal, except for magnesium.

Brass | Burr/slag thickness should not exceed 0.75mm | Effective removal of burrs but can result in stains on surfaces but can be cleaned well | Degrease, pre-thermal deburring | Light acid soap wash | Blasting, Tumbling |
Carbon Steel | Burr/slag thickness should not exceed 1mm | Effective removal of burrs, some oxide stains may remain | Degrease | De-Ox acid wash | Blasting |
Cast Iron | Burr/slag thickness should not exceed 1mm | Effective removal of burrs, some oxide stains may remain | Degrease | De-Ox acid wash | Blasting |
Copper | Burr/slag thickness should not exceed 0.75mm | Effective removal of burrs but can result in stains on surfaces | Degrease | N/A | Blasting, Tumbling |
Glass Filled Nylon | Burr/slag thickness should not exceed 1mm | Effective removal of burrs | Degrease | N/A | Blasting, Hand Deburring |
Stainless Steel | Burr/slag thickness should not exceed 1mm | Effective removal of burrs, parts look somewhat dirty post-cleaning | Degrease, pre-thermal deburring | Acid wash and ultrasonic clean | Blasting, Electropolish, Passivation |
Titanium | Burr/slag thickness should not exceed 0.75mm | Burr attachment point burns back but not fully removed, can result in stains on surfaces | Degrease | Ultrasonic clean | Blasting, Passivation |
Zamak | Burr/slag thickness should not exceed 0.75mm | Effective removal of burrs but can result in a chalky dull appearance | Degrease | Light detergent wash | Blasting |
