Improve
Control the appearance, roughness, and consistency of your surfaces according to their function.
Beyond aesthetics, finishing adapts roughness, consistency, topography, and appearance to the intended use of the part or equipment and to the requirements of your industry.
The challenges
01
Adjust roughness and irregularities according to the desired characteristics.
02
Obtain a consistent appearance across the different areas or parts to be treated.
03
Define the finish based on use, maintenance, and any subsequent treatments.
Your need
Technochim selects the mechanical process based on the material, the initial surface condition, and the desired result. Mechanical polishing, brushing, and microbead blasting produce different surface conditions and address specific objectives.
Our approach
The choice of mechanical finishing depends on the expected result, as well as the material, initial condition, geometry, and accessibility of the surfaces.
01
Characterizing the initial condition
Examine the surface, defects, existing finish, and applicable criteria.
02
Defining the finish
Specify the desired appearance, roughness, or surface characteristics.
03
Selecting the process
Choose the appropriate mechanical treatment and finish level.
04
Checking the result
Verify the consistency and characteristics defined for the intervention.
Understanding finishing
Mechanical finishing processes do not act on the surface in the same way.
The choice between these processes therefore depends on the surface’s function and the expected result. They are not interchangeable.
Mechanical polishing uses a controlled sequence of abrasives to progressively reduce irregularities and achieve the desired level of finish.
Brushing produces a directional, consistent finish, particularly when surface appearance is a key criterion of the project.
Microbead blasting works by projecting microbeads onto the surface and produces a specific finish, different from that obtained by polishing or brushing. It alters the surface topography without necessarily reducing roughness. The result depends in particular on the material, the microbead characteristics, and the projection parameters.
The average roughness Ra is an important parameter for characterizing a finish, but it does not describe the entire surface on its own.
Two surfaces can have a comparable Ra while having a different topography and surface condition.
Depending on the project’s objective, Technochim can therefore incorporate other surface characterization elements to assess the result beyond a single roughness value.
When the objective also involves microtopography or surface properties, a chemical or electrochemical treatment can complement or serve as an alternative to mechanical finishing.

Technochim expertise
Technochim combines mastery of mechanical processes with knowledge of surface conditions to select the finish suited to the desired function.
This expertise also makes it possible to assess the value of a complementary chemical or electrochemical treatment, depending on the material, initial condition, and desired surface characteristics.
