The Metal Bond Diamond Frankfurt Abrasives are designed for the rough grinding and calibration stages of fully automatic marble polishing lines.
I. Applicable Stone Types
1 Various Natural Marbles
Beige marble, Nero Marquina (Black & White Vein), grey marble, high-hardness marble, and dark, heavily veined marble; the preferred choice for stones with high feldspar or quartz content that are difficult to grind.
2 Travertine and Limestone
Porous travertine often exhibits significant surface unevenness after sawing; metal abrasives offer strong cutting power to rapidly level the surface.
3 Terrazzo, Engineered Marble, and Cement-based Composite Stone
Contains hard internal aggregates that cause rapid wear on standard magnesite abrasives; metal Frankfurt abrasives offer superior wear resistance and stability.
4 Epoxy/Resin-filled Stone
Rapidly grinds away residual glue and repair layers from the slab surface while ensuring uniform thickness.
5 Thickened Engineered Stone and Thick Raw Slabs
Deep saw marks and significant surface irregularities require high stock removal capabilities.
❌ Stone Types Not Suitable
Onyx, translucent soft luxury stone, and ultra-soft thin marble slabs; the rigid metal matrix can easily cause deep scratches, edge chipping, or stone breakage.
II. Applicable Slab Types
1 Standard 20mm(18mm) Marble Slabs, Strips, and Project-spec Slabs
Mainstream slab formats for global marble processing plants; standard consumables for rough grinding and calibration.
2 Thickened Raw Slabs and 30–50mm Thick Stone
Significant surface irregularities following gang-saw cutting require powerful roughing capabilities.
3 Exterior Wall Cladding, Paving Stone, and Stair Tread Blanks
Uniforms thickness to ensure consistent results during subsequent polishing stages. Pre-treatment of rough blanks for countertops,
4 vanity tops, and shaped stone pieces.
Initial leveling process for slab batches.
❌ Not suitable for:
Ultra-thin slabs, finished polished slabs, or precision-finished shaped/curved slabs.

III. Applicable Processing Stages
Used only for the first stage of rough processing in a marble production line; cannot be used independently for medium or fine polishing:
- Removes deep saw marks and surface pits/depressions left by gang saws or diamond saw blades;
- Levels the slab surface, eliminates height variations, and ensures uniform thickness;
- Grinds away surface epoxy resin, repair fillers, and layers of dirt or stains;
- Removes significant stock from thick slabs and raw blocks, reducing consumable wear in subsequent medium and fine polishing stages.
Standard complete marble polishing sequence:
- Metal bond Diamond Frankfurt Abrasive (#24~#320) →
- Magnesite Diamond Frankfurt Abrasive (#120~#400) →
- Resin bond Diamond Frankfurt Abrasive(#800~#3000)
IV. Compatible Processing Equipment
1 Fully automatic continuous marble polishing lines (mainstream)
- Compatible with Keda, Breton, Simec, and Intermac 8/12/16/20-head "T3" polishing machines; fits standard T105 bases and directly replaces OEM consumables.
2 Heavy-duty automatic bridge-type slab grinders and multi-head calibration/grinding equipment
- For leveling raw block batches at quarries or large stone processing plants.
3 High-speed, 24-hour mass-production polishing lines
- Water-cooled models are recommended for stable heat dissipation and extended service life.
4 Custom-built equipment
- Supports custom base sizes for niche imported or domestic machinery.
❌ Not suitable for:
- Granite Fickert polishing lines, small handheld grinders, or stone floor restoration machines.
V. Target Customers / Factory Types
1 Large-scale marble mass-production factories (24-hour continuous assembly lines)
Core target customers prioritizing ultra-long service life; they seek to minimize downtime caused by abrasive block replacement and save on labor and time costs.
2 Specialized processing plants for hard marble, travertine, and terrazzo
Standard magnesite abrasive blocks wear out too quickly; metal Frankfurt-style abrasives are essential consumables.
3 Large-scale manufacturers of stone engineering slabs and exterior wall cladding
Require uniform calibration for high-volume slab production and consistent processing efficiency.
4 Overseas importers/wholesalers and regional distributors of stone consumables
Maintain ready stock; supply as complete sets alongside resin and magnesite Frankfurt abrasives.
5 Quarry-based primary processing workshops
On-site leveling of raw blocks before shipment for final processing.
VI. Suitable Operating Conditions
- High-speed slab transport via conveyor belts; significant cutting allowance (stock removal);
- 24-hour continuous processing (common in major marble regions like Turkey, Italy, and the Middle East);
- Slabs with extensive epoxy repair layers or uneven raw block surfaces;
- Suboptimal cooling water supply; requires versions with integrated cooling channels to dissipate heat and prevent burning.
❌ Unsuitable Operating Conditions
- Dry grinding (lack of water);
- low-speed, intermittent processing lines for soft stone;
- mirror-finish high-gloss polishing stages.
