Theomeca produces everything from single pieces to small or medium series.
Furthermore, our mastery of our processes as a whole allows us to cover the range of your needs with an available human potential of more than 3,500 hours/month.
This equipment allows us to offer our customers support services for the production or improvement of high-precision mechanical parts.
Description of the THEOMECA machine park:
- 3 electrical discharge machining (EDM) machines (die sinking and wire)
- 5 three-axis machining centers
- 1 five-axis machining center
- 2 horizontal 4-axis bi-pallet machining centers
- 2 digital lathes with XZ axes
- 3 CNC lathes with XYZ axes and bar feeder
- 1 twin-spindle CNC lathe with XYZ axes
- 1 large-dimension (3000 x 1500 mm) 3-axis vacuum table
- 1 radial drill
To manage this machine park, Théomeca uses CAM software (TopSolid) which accepts a wide variety of file formats (SolidWorks, Catia, AutoCAD, etc.). Furthermore, our machinists have access to regular training to take advantage of the latest software updates.
Machining (or precision machining) is a process for manufacturing mechanical parts by removing chips, which, as its name suggests, leaves no room for defects. Machine tools allow the part to be given the desired dimensions and shape. The principle of machining a part is achieved through two relative movements: cutting and feeding.
This technique allows Théomeca to work with the most varied materials on 3 to 5 axes: Aluminium, Plastic, Composite materials, Stainless steel, Steel, Brass, Copper, Bronze, Titanium.

Three main families of machining processes
Milling
This operation is typically performed using a CNC machining center (numerical programming and control) equipped with a milling cutter. Milling is carried out according to the climb milling principle: the tangential cutting force follows the workpiece as it is milled, and this process also allows for excellent surface finishes. Milling makes it possible to produce even the most complex parts.
The filming
The operating principle of a CNC lathe is to manufacture a part whose shape results from a rotation around an axis. The manufactured part is created by cutting tools moving along three to five axes.
All of these movements allow the material to be machined and the desired shape to be obtained (cone, cylinder, etc.).
Electrical erosion
As its name suggests, this machining process allows workpieces to be worked using an electric arc. The workpieces and the electrode , separated by a few tenths of a millimeter , are immersed in a dielectric fluid. For this process to be used, the workpieces must be conductive. Electrical discharge machining (EDM) has the advantage of precision (5 µm) and its ability to work with materials of extreme hardness (alloys, graphite, carbide, etc.).
There are two electro-erosion techniques mastered by Théomeca: die sinking (or EDM) and wire cutting.
