|Abrasives||Materials with hardness and cutting capacity (angularité) allowing a removal of material on the surface of the contacting parts. In general, they are in the form of powders and are then glued to or embedded abrasive bands heart abrasive ceramic media or plastic.|
|Additive||Liquid, paste or powder with various functions (degreasing, brightening, scouring, anti-rust protection (or protection against corrosion)) used in the process tribofinishing.|
|Brillantage||Method for making a brilliant piece, without necessarily improving its roughness.|
|Equipment tribofinishing the top of the bowl which is fixed and the bottom (bottom) en rotation. This equipment includes a rotating seal sometimes susceptible to abrasion. Similarly, the presence of the gasket makes it difficult the use of abrasive powders in general very thin.|
|Satellite centrifuge||Rotary vibratory finishing equipment operating on the basis of planetary motion (dual axis of rotation) to rotate at very high speed.
The energy produced by this equipment can significantly reduce cycle times and if necessary use, Media very small.
|DCO||Chemical Oxygen Demand. Determines the organic load, which affects the generation of foam and organic pollution caused by harmful additives. A lot foaming water is usually heavily loaded COD.|
|Deburring||A method for removing burrs or surface defects (for example,
vibration milling, bavures of drilling).
|Emerisage||A deburring method or surface smoothing performed manually or on a tourret.|
|Drilling||Machining operation to a material removal, the piece being fixed, the rotating tool is moving|
|Average||Products made of various materials (binders) such as ceramic or clay for ceramic media or visual media for polyester, which are introduced in abrasive powder. The media are characterized by their shape and dimensions ; but the less obvious but fundamental parameter is the composition and size of abrasives which are integrated at the heart of media. Mostly, alumina or silica are preferred, but new abrasive tend to be recommended for specific applications (galvanic deposits or issue weldability).|
|MESH||English units commonly used to measure the abrasive powder. (See scale of correspondence : www.abcswisstech.com/pdf/tableautaillesdegrains.pdf).|
|Passivation||A method for reducing the effects of oxidation (corrosion) by modifying the pH (generally alkaline).|
|pH||Hydrogen potential, used to determine whether a medium is acidic or basic. Extreme value: 0-14. The pickling or descaling (deoxidation) se font, in general, in milieu acide. Degreasing and passivation (anti-oxydation) se font, in general, in alkaline milieu.|
|Carrier||Synonymous average abrasif.|
|Poudre abrasive||Powder used for deburring or polishing of a workpiece. The powders are
characterized by the constituent material and grain size (en MESH).
|Out (ou Rz ou Rt)||Determining the roughness values.(expressed in microns or microns). They allow to describe a surface as this measure is related to the brightness ; thus, it is possible to obtain a matt surface roughness with excellent, as well as a shiny surface with an average roughness.|
|Shelving||Round action or soften the edges of a room. The rays can stop
be measured very accurately to define a perfectly reproducible method.
|rH||ORP or Redox expressed in Volt. It corresponds to the stability of a metal complex in a solution and allow to quantify the addition of a reducing. This value is used as part of the remediation of water from vibratory finishing media with copper.|
|RPM||Rotation Par Minute (unit for the rotational speed).|
|Satellites||Often coated on the inside with a layer of polyurethane or other metal used in satellite speakers centrifuges.|
|Savo||Synonymous with chemical additives.|
|Smuritropie||Technique in which the workpiece is held by a clamping. The workpiece is rotated (or circular movement epicyclic) and introduced into a bed of media; these are either static, Pulsating either. The advantage of this technique is the absence of collisions between parts, the speed and quality of the process. By cons, it is expensive and tools required by the complexity of the equipment.|
|STEP||Water treatment plant to protect the environment or to recover the precious metals in the water.|
|Tamiseuse, Tamiseur||Equipment for dimensionally separate products (par ex. between media and parts).|
|Rotary barrels||Vibratory finishing equipment generating rotational motion. It was the first equipment to be developed. The movement generates a kind of wave that allows parts to slide over the media by reducing the phenomena of shock often encountered in vibrators. The disadvantage of these devices is the slow process that can last several tens of hours.|
|Toroïdal||Having the shape of a torus|
|Batch Processing||Treatment wherein all ingredients (also water) are introduced before starting treatment without added during treatment|
|Treatment in an open circuit||Treatment with continuous supply of water is, additives and / or any abrasive during processing and corresponding rejection.|
|Mass finishing||Methods for treating chemical-mechanical area in which equipment generates a rotating or vibrating movement ; the workpieces are contacted with media, any abrasive powders, additives (liquid, powder or paste) and generally, Water.|
|Tristar||Particular form of abrasive media, which is based on a triangle whose vertices are angles less than 60 ° (often of the order of 35 à 45°) . This particular form allows the media to reach areas of parts very difficult to access, while ensuring that there is no blockage of the media in sensitive areas. More simply, it is a star 3 branches.|
|Trowalisation||Synonyme de tribofinition.|
|Circular vibrator||Vibrators are welded equipment consisting of a frame, a metal tank filled with a layer of polyurethane (allowing both to protect the parts of the shock and not wear out too quickly), and an engine equipped with an adjustable eccentric weights generating vibratory regime. Rotary vibrators have a circular bowl shape and dimensions ranging from a few liters to several thousand liters.|
|Linear vibrator||Vibrators are devices welded abrasive compounds, a metal tank filled with a layer of polyurethane (allowing both to protect the parts of the shock and not wear out too quickly), and an engine equipped with an adjustable eccentric weights generating vibratory regime. Linear vibrators have a rectangular tank and dimensions ranging from a few liters to several thousand liters.|
