The TEM method
Thermal deburring (TEM) is a process of removing burrs caused by production (due to milling, drilling, etc.) from various machine parts. For this purpose, the workpieces are placed in a bell-shaped deburring chamber which is hydraulically closed by a closing plate.
An accurately defined mixture of gases is fed into the deburring chamber via a gas metering system and ignited by a spark. The temperature of the subsequent combustion ranges from 2,500 to 3,300 °C (4,532 to 5,972 °F) and rises above the ignition temperature of the burr. The excess oxygen inside the deburring chamber leads to a chemical reaction which vaporizes the burr completely within 20 ms.
