Vitrified grinding disc is made of grinding disc matrix and super hard diamond grinding pellets by epoxy resin adhesive, and can be made into various shapes such as regular hexagon, sector, square,circular, trigonometrical, hexagonal pellets (other shapes can be customized).
The diameter of the round pellet is 20-35mm thick and 5-10mm. The glue joint is too sharp to grind small workpieces; while for Hexagon pellets, length 13mm thick 5-10mmand with a smaler glue joint (2mm) can get better wear resistance.
Vitrified superhard grinding disc can be divided into vitrified diamond grinding disc (the color of diamond pellets are white and yellow) and vitrified CBN grinding disc ( the color of CBN pellets are black or brown).
Take the 650mm diamond disc for example(the matrix is recycled from a customer)
There are 42 water holes and 6 connecting holes on the surface of the matrix (all in the upper plate and none in the bottom platel). Also there are 4 symmetrical serial loading holes on the periphery, and the matrix can be recycled (generally at least 50 times).To make recycled matrix look good, it will be painted before packing.
Moresuperhard Diamond/CBN grinding discs are widely used for grinding the surface, suitable for steel, cast iron, copper, carbide,PCD/PCBN inserts, hard alloy, ceramics, monocrystalline silicon and other processing. It can be widely used in hydraulic pneumatic components, hydraulic motor parts, automobile fuel pump parts, refrigeration compressor parts, oil pump oil.
Accuracy of finished workpiece: roughness 0.1um-1.2um,
flatness 0.001mm ~ 0.004mm,
equal height ≤0.002mm.
Applicable equipment: Wendt WBM, Viotoo, AMT, Stahli, Peter Wolters, Diskus, Agathon T&B, Fujisanki, Supfina, Melchiorre, Koyo, Lam Plan, Speedfam, Kemet, Gardner and other DDG machines.
Moresuperhard can also provide matching dressing grinding wheel of DDG wheel:
According to the different particle size, accuracy of the diamond and CBN grinding disc to choose the dressing wheel, making dressing easier and more time saving. Mostly we use are silicon carbide(GC) dressing wheel while diameter is 205mm, grit 180#.
Moresuperhard supply full series vitrified diamond and CBN grinding wheels for the top and bottom grinding. This flat grinding can achieve very high precision in height and parallelism, so it best choice for your PCD,PCBN and other materials cutting inserts. This double face grinding is much more efficient than normal surface grinding.
