The Thermal Energy Method
(TEM) of deburring
The process itself could not be more simple. The fuel gas and oxygen rich mixture surrounding and permeating the component is ignited. The blast lasts for around 20 milliseconds, during which time the temperature increases up to a maximum of 3,500 degrees celsius. Material that has a large surface area to mass ratio (ie burrs) are unable to dissipate the heat fast enough and go beyond their ignition temperature and oxidise completely away.
The heat in these burrs can only dissipate by oxidisation or through the root of the burr where it dissipates safely throughout the main bulk of the piece. If required, any oxide deposited on the surface of the component, can be cleansed with a wash.
However the parameters which control the fuel / oxygen mix; the heat generated; the maximum temperature; the resultant pressure and the duration are intensely complex. Achieving the optimum condition though, is possible. It is this computerized control of every factor that allows the process to be individually tailored for any component irrespective of material, size or complexity, and for the process to be precisely, and consistently repeatable.
