Mechanical polishing
Mechanical polishing is the unavoidable step that has to be carried out when modifying surface finishes.
DBP-MAYET has a unit that specialises in polishing stainless steels, chromium alloy steels, nickel based alloys, titanium and titanium alloys.
DBP-MAYET is able to offer a wide range of finishes that meet the current demands of the following industries: nuclear, wine making and the wine market, medical, pharmaceutical, chemical, art and decoration, aeronautics, nautical, agri-food
- Medium to very fine brushed texturing
- Emerizing – all particle sizes
- Mirror finish polishing
All families of austenitic, martensitic, ferritic and duplex stainless steels are treated in our mechanical polishing unit with roughness ranging from 3.2 μm to 0.05μm.
Our specific procedures in the use of polishing media and the choice of abrasives satisfy the demands set by reference systems and technical specifications applicable to the various business sectors
> Our abrasives meet the requirements set by FEPA standardisation.
We have a 600 m² area
equipped with a 5 tons overhead gantry
and a 1800 kg fork-lift truck.
- 2 twin spindle grinders including 4 emerizing stations
- 2 twin spindle grinders including 4 cotton-sisal polishing stations
- 5 flexible spindle polishing stations
- 1 emerizing and polishing bench for treating tube and shell outer surfaces (Ø 100 to 2 200 mm)
- 1 automated emerizing and polishing cross-arm (300 to 2,500 internal and external Ø)
- 1 positioner having a 1,000 kg capacity
- 1 turning gear having a 10,000 kg capacity
- 3 surface roughness testers
- Contact-free surface roughness testers using interferometry (producing images)
- 1 comparator with feeler arm (for measuring thickness)
- 1 thickness checking device (micron comparator)
- Caliper and micrometer
The surface deterioration and contamination diagnostic consists in determining :
- the sources of contamination and deterioration : reactors, storage tanks, pipes, hoppers, autoclaves, special machines etc.
- potential treatment methods
- quantifying the condition of surfaces affected by this contamination or deterioration
- a detailed report of surface conditions and the preparation of a proposal covering the reinstatement compliance for your installations
