TEM-Thermal
Deburring

The TEM process is one of the fastest and most cost-effective removal processes in which high quality and repeatability are achieved. Burrs, adhering particles and deposits are reliably removed. The machining of a complex or many smaller components is possible after a short changeover time.

The primary areas of application are cast and turned parts as well as distributor blocks. Through the process, considerable savings can be achieved on bodies for hydraulic and pneumatic valves, as well as castings with internal bore intersections. For zinc die-cast parts, the removal of machining and casting burrs occurs simultaneously. In addition, precision turned and milled parts can be deburred in a matter of seconds using TEM.

The energy carrier of the process is gas, which is distributed evenly within the deburring chamber and the workpiece. For gas, especially under pressure, no opening is too small to penetrate. This means that gas flows around every machining burr, every edge, every shape burr and every particle.

The deburring success depends on the thermal conductivity and the specific heat absorption of the metals. Ferrous materials as well as metals such as aluminum and zinc alloys can be processed particularly well. Stainless steel can also be processed, but with limitations, by thermal deburring.

In principle, thermal deburring of plastics is possible. Due to low gas pressures and process temperatures, as well as low melting points of thermoplastics, the process requires special parameters for low energy densities. The thermal deburring machines from ATL are equipped with high-quality control technology so that the processing parameters for thermoplastics can be set sensitively and reproducibly.

In the case of smaller components, the process reaction can cause the workpieces to collide and be damaged. To avoid this, the components are picked up in fixtures. Larger components, such as hydraulic blocks, can usually be machined without a fixture.
