Definitions
- the present invention relates to so-called "super-abrasive" grinding wheels.
- This term denotes grinding wheels with very high abrasive power, based on very hard abrasive particles, in particular diamond or cubic boron nitride, and an agglomerating agent which makes it possible to retain and hold these particles in place.
- This binder can be of three types: it can be a resin, in particular a polyimide or phenolic resin. It can also be a vitrified binder, in the form of a ceramic matrix of the alumina, alumina-silica or carbide-silica type. The binder can also be based on a metal matrix, and it is this third type of binder that the invention is more particularly interested in, since it has a particularly advantageous mechanical strength.
- a constant difficulty in the grinding process is to properly evacuate the dust or other reject products generated by the operation.
- a medium generally water
- the grinding wheel simultaneously attacking a whole portion of the surface of the treated article, the coolant has difficulty progressing towards the entire portion being treated. There then occurs a certain accumulation of rejections.
- grinding is thus systematically accompanied by the formation of a layer of glass paste which tends to oppose the action of the grinding wheel and slows down the operation of grinding by forcing to operate in several passes.
- the object of the present invention is to provide an improved type of superabrasive grinding wheels with agglomerating metal matrix allowing better management of the problem of dust and other discharges.
- the subject of the invention is a super-abrasive wheel based on very hard abrasive particles of the diamond or cubic boron nitride type and a agglomerating with a metallic matrix, and which also contains so-called "porogenic" adjuvants. This term includes additives which have the function of creating a certain porosity within the agglomerate of the grinding wheel.
- adjuvants are to be chosen according to the manufacturing process of the grinding wheels. In particular, they must be able to withstand the correct pressure and temperature. This is the reason why adjuvants are preferably used in the form of hollow ceramic balls, in particular based on silicon oxide and / or aluminum such as alumina or mullite. Mullite is an aluminum silicate of the 2Si0 2 -3AI 2 0 3 type . These balls are advantageously chosen with an outside diameter between 1 micron and 3 mm, in particular between 100 microns and 1 mm. Its walls preferably have a thickness of between 2 and 8, in particular between 4 and 6 micrometers.
- these porogenic additives are added to the grinding wheel in a proportion of 1 to 80% of the total volume of the grinding wheel, in particular between 5 and 50%, or approximately 30% of said volume.
- the operating mode of these pore-forming aids is as follows
- the hollow balls which are found on the surface break and the surface of the grindstone becomes pockmarked; the glass paste can then accumulate in these hollows without hampering the progress of grinding.
- the coolant can progress continuously at the interface between the grinding wheel and the treated article and thus penetrate to the bottom of these hollows, expelling the glass paste - or any other type of dust - which is thus evacuated to finally be returned by the bottom of each hollow formed by a ball.
- the coolant thus acts on a much larger surface than the single surface of the belt of the abrasive wheel, allowing direct cooling to a depth of the order of the diameter of the balls, which increases by as much the cooling efficiency and thereby slows the wear of the grinding wheel.
- the rate of balls in the grinding wheel is to be modulated according to the type of articles to be ground.
- the metallic matrix of the bonding agent can be chosen according to the applications for which the grinding wheel is intended.
- Cobalt is widely used, but also bronze, silver which has the distinction of being relatively ductile, iron or copper.
- additives can be added to this matrix, in particular such as tungsten carbide, in order to increase the resistance to erosion of the grinding wheel.
- the abrasive particles of the grinding wheel preferably correspond to 5 to 60% of the total volume of the grinding wheel, in particular from 1 0 to 30% of said volume. They can be in rounded form or in the form of needles.
- FEPA code a standard code from European manufacturers of abrasives
- a grain size according to this code between 4 and 1 1 82, which corresponds to an "average diameter" particle size of 4 microns at 1.100 mm.
- a grain size is chosen between 40 and 90.
- the finest abrasive particles making it possible to obtain the surface condition of the part to be ground the most. polished.
- the grinding wheel according to the invention is used for machining or grinding glass articles, in particular for grinding the edges of glass sheets.
- An example of a grinding wheel according to the invention is produced in the following manner: a grinding wheel is produced according to known manufacturing methods with 15% by volume of diamond particles of grain size 91, and 30% by volume of hollow beads of mullite with an outside diameter of about 0.5 mm and a wall thickness of about 5 micrometers, with a cobalt binder. The results are convincing: the grinding of the edges of glass sheets is facilitated by better evacuation of waste, better cooling of the grinding wheel, moreover leading to an increase in the life of the grinding wheel by almost 30% compared to a similar wheel without alumina beads.
