Thermal deburring (TEM - Thermal Energy Method) is a process for removing production-related burrs from a wide variety of machine parts, e.g. by milling or drilling. Scientifically correct, TEM is referred to as a "thermal-chemical deburring process" and, according to DIN 8590, is assigned to the subgroup of ablative processes "chemical ablation".
In the TEM process, the material to be removed is burnt because a chemical reaction takes place between the material and the gas mixture.

For this purpose, the workpieces are placed in a bell-shaped deburring chamber which is closed hydraulically by means of a sealing plate. A precisely defined mixture of fuel gas and oxygen is fed into the deburring chamber via a gas dosing system and will be ignited. During the subsequent combustion, temperatures of 2,500-3,300 °C are generated. The burr to be removed reaches its ignition temperature and reacts with the excess oxygen in the deburring chamber. This leads to a complete combustion of the burrs within 20 ms.

Various metallic materials as well as all thermoplastics such as PA, PE, PTFE, PUR and PMMA, but also injection moulded parts without glass fibre content can be processed. The cycle time for thermal deburring is less than two minutes.
