Thermal Deburring

“TEM – Thermal Energy Method – is a process increasingly globally adopted by leading production companies in order to obtain important targets of quality.”

 

Process

The thermal deburring is a system aimed at the elimination of burrs on the components made of oxidable materials that come from specific processes (mechanical, die-casting, etc.). The process uses, according to a chemical-physical principle, the heat generated from the ignition of a suitable combustible mixture, just as in the case of internal combustion engines.

The obtained energy uses the oxygen, contained in the original mixture, to remove burrs, waste and unwanted material present on the edges, within the cavities and surfaces more or less hidden of the treated details. Any threaded parts, which are present on the particulars, are not affected by the process due to the geometry of the same thread.

The pieces at the end of treatment, have a layer of oxide on their surfaces.

Treatable materials

The below materials can be thermally deburred:

  • oxidizable metal parts that are obtained by casting or mechanical working;
  • items made of cast iron, steel, copper and its alloys, aluminum and its alloys, not yet heat treated and free from oil or grease.

Any heat treatment has to be performed after thermal deburring.

Usually can be removed burrs and scraps of a thickness not exceeding 0,1 mm for aluminum, copper and their alloys, and up to 0,3 mm for ferrous materials.
It’s possible to treat also stainless steel with only the heat released by the combustion of the mixture.

Examples of work

1
Steel and cast iron - hydraulic , automotive, mechanical
2
Zinc alloy, aluminum, brass, die-cast and machined parts
3
Components in steel and brass
4
Small parts in brass
5
Other details and small parts in brass
6
Aluminum body and parts in zamak
7
Other parts in machined steel
8
Other die cast zamak parts
Example of post treatment

Post treatment

The thermal deburring oxidizes the surface of the treated parts. To restore their original appearance a deoxidation treatment is enough.

SGM has developed over the years a deoxidation process without the use of acids and which is easily adoptable by any industrial reality. Today SGM uses:

  • Aqueous andenvironment friendly products, that do not require rinsing;
  • Industrial washing machines equipped with an ultrasonic and vacuum creating system.

The process meets the needs of ecological preparation and especially of deoxidation of thermally deburred ferrous parts, cast iron and aluminum.
