TEM deburring

> TEM machinery construction > TEM deburring


The TEM process is used in the hydraulic-pneumatics, automotive, die casting and general mechanical engineering sectors.

The process can be used on the following components:

Burrs are located in hard-to-reach areas
Workpieces with maximum “burr-free” requirements
For a large number of different types and quantities, where a universal process is required.
Reliable removement of burrs after mechanical processes such as drilling, milling, turning and grinding.
Deburring of zinc die casting parts.

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.
