The provision by MMP treatment is dedicated to the customers having to carry a particular care to the completion of the surface state of their parts. The MMP process can be approached by 3 different ways: 

• Superfinishing of new surfaces
• Preparation of surfaces, before and after hard coatings
• Refreshing of surfaces already used

Moreover the 2 big application domains where the MMP is used are: 

SuperPolishing

SuperPolishing treats the parts particularly having to answer esthetic criteria like some kind of moulds (pens, cosmetic) and ended products (watch industry). The treatment characteristics are: 

• Filtering  by band-pass
• Control of the secondary micro-roughness
• Suppression of primary micro-roughness

SuperBrightning

SuperBrightning treats the parts particularly having to answer functional criteria like the plastic injection (tops, connectors), the parts of friction like the tooling of cutting, striking, stamping and mechanical parts of high precision like the gears, gearwheels or moreover the parts of slipping like the engines of aircrafts and cars, etc. The treatment characteristics are: 

• Filtering by low-pass
• Suppression of secondary micro-roughness
• Controlled leveling of primary micro-roughness

Preparation of surfaces before deposit and superfinishing of deposits

The deposits of hard coatings of low thickness, by PVD, CVD, etc, can bring an effective solution to the problems involved in the wearing down by friction or slipping of surfaces and in the problems involved in adherences and chemical depreciations due to the effects of cold joining. It is however possible using the MMP micro-machining process, to increase the quality of surfaces of the parts, which must receive thin deposits of layers, in a sometimes-considerable way. 

The purpose of the MMP process, when it is carried out before deposit, will be to improve resistance of the substrate and when it is carried out after deposit, its goal will be to suppress from the surface of the deposits, all the excrescences (droplets) generated by their mode of growth. The deposits most concerned, today, in the field of the mould are the thick chromium deposits and thin nitride deposits of chromium and titanium. 

The MPP micro-machining of the chromium deposits deposited on moulds for the manufacture of joints and elements for the car industry, made it possible to increase the production resulting from these moulds in a considerable way. It should be known that in these fields the time of cleaning of surfaces, which is carried out in the course of production by robots, could represent a considerable proportion of the total time of production.
