Disques de meulage à liant métallique et résine pour le polissage du granit

DINOSAW metal and resin bond grinding discs are the disc-format grinding program on granite polishing machines. Metal bond discs handle the coarse grinding stage with grits 50#, 10S#, 200# and 400#, delivering high processing efficiency and a long lifespan of polishing. Resin bond discs handle the fine grinding stage with grits 500#, 800#, 1500# and 3000#, refining the slab surface before polishing discs take the final gloss. Both disc types install on automatic continuous polishing machines or single head grinding machines, and both are available in four diameter classes: 4"/100, 5"/150, 6"/200 and 10"/250 mm. Run metal discs first to level the slab, resin discs second to close the scratch pattern, and the polishing stage receives a surface it can finish at full gloss.

Grinding Disc Applications in Granite Slab Production

Grinding discs sit between calibration and polishing: metal discs remove the saw-cut face and level the slab, resin discs refine the surface so polishing heads can finish at uniform gloss.

DINOSAW metal and resin bond grinding discs are the disc-format grinding program on granite polishing machines: metal discs take the coarse grinding stage, resin discs take the fine grinding stage, and polishing discs finish the gloss — one mounting system covering every stage between calibration and buffing.

Real Grinding Performance & Key Metrics

Four Diameter Classes

Discs are supplied in 4"/100, 5"/150, 6"/200 and 10"/250 mm, so each grinding station on a continuous polishing machine or single head grinding machine gets the diameter its head position requires.

Metal Bond Coarse Stage

The metal grit program levels granite slabs after cutting or calibration. High processing efficiency removes thickness relief fast, while the metal bond gives a long lifespan of polishing-line duty.

Resin Bond Fine Stage

The resin grit program erases the coarse scratch pattern step by step and closes the surface, so the polishing discs downstream take the final gloss instead of fighting deep scratches.

Metal Bond for Coarse Stock Removal

The metal bond locks diamond grit firmly in place, so 50# to 400# discs keep cutting through hard granite relief without premature grain loss. This is what delivers the high processing efficiency and long lifespan of polishing that the coarse stage depends on.

Resin Bond for Fine Surface Refinement

The resin bond wears progressively, exposing fresh fine diamond at 500# to 3000# as the surface refines. The gradual exposure keeps the fine stage cutting instead of glazing, which is what prepares the slab for the final polishing discs.

Four-Diameter Disc Program

Diameters of 4"/100, 5"/150, 6"/200 and 10"/250 mm let the program follow the machine instead of forcing the machine to one disc size. Each grinding station on a continuous polishing line gets the diameter its head position and working width require.
