Thermal deburring combines aggressive deburring with fine finishing.

SPHOTA removes burrs of steel, cast iron, brass, Zinc or aluminum created due to operations such as turning, milling, broaching, grinding or die-casting. Using SPHOTA, both internal and external burrs from work pieces can be removed safely. In thermal deburring, the work pieces are placed in a pressure chamber. The chamber is then closed and filled with a mixture of gases, which is later ignited.
Due to the instantaneous high temperature the burrs are burnt since their surface is large relative to their volume. The work pieces are moderately heated.
In order to set free the energy required, the gas mixture has to be compressed prior to the ignition. Higher the chamber charging pressure, higher is the energy, which results in high deburring efficiency.
Gas as an energy transmitter can be easily metered by pressure and has the advantage of an even distribution in the space available.
Consequently it also fills cavities and holes in the work piece. Therefore burrs located internally are also removed during the combustion of the gas.
The burr that vaporizes deposits on all the cooler surfaces inside the deburring chamber.
