Metal Frankfurt Abrasive
Manufacturering Frankfurt Abrasive
Metal-bond diamond Frankfurt abrasive blocks (commonly known as "horseshoe" metal blocks or Frankfurt Block) are specialized consumables for coarse grinding and calibration on fully automatic polishing lines for marble, travertine, limestone, and engineered stone. They serve as the marble counterpart to granite L140 metal Fickert blocks and fit T3/T105 horseshoe-shaped bases. They are designed exclusively for the initial stages of production—specifically rough grinding, removing saw marks, and calibrating slab thickness—and are not intended for high-gloss fine polishing.
Cheefung metal bond diamond frankfurt blocks (horse shoe shape T3/T105) are heavy-duty rough calibration abrasives exclusively designed for full-automatic marble, travertine & terrazzo continuous polishing machines. Made of sintered copper-cobalt metal matrix with high-concentration industrial diamond grains, they remove deep gang saw scratches and level uneven slab surfaces efficiently as the first stage of stone polishing flow.
Competitive advantage
Our products sell well in markets such as Shuitou, Brazil, Turkey, India, Spain, and Italy, and boast five core advantages.
High stock removal for rapid slab leveling
boosts overall production line capacity
The metal-bond matrix allows for deep cutting, removing deep saw marks and surface irregularities in a single pass—eliminating the need for multiple grinding cycles. It enables a 20%–35% increase in conveyor speed while reducing spindle pressure, equipment wear, and electricity consumption.
01
Exceptional service life
significantly reduces downtime for tool replacement. Processes 35,000–52,000 m² per unit (based on standard 20mm marble slabs with adequate water cooling). Its lifespan is 1.5 times that of resin Frankfurt blocks and 15–20 times that of magnesite (Sorel cement) horseshoe blocks—ideal for high-volume, 24/7 marble production facilities in Turkey, the Middle East, and Italy.
02
Stable self-sharpening performance
resists dulling and surface burning during prolonged use. The metal matrix wears evenly, allowing dull diamonds to shed and continuously exposing fresh, sharp abrasive grains. It prevents stone dust buildup and surface scorching or blackening, ensuring light-colored marble remains free from burn marks.
03
Suitable for hard marble, terrazzo, and thick raw slabs
While standard magnesite blocks wear out rapidly on high-hardness marble, thick terrazzo, or epoxy-repaired slabs, these metal Frankfurt blocks offer superior wear resistance and stability; they can also remove residual epoxy resin or polyester adhesive layers from the slab surface.
04
Universal compatibility
supports full customization and integrated supply. Features a standard T3 horseshoe base fitting, requiring no spindle modifications. Options include an inclined-slot water cooling structure for optimized heat dissipation. Services include OEM branding, custom stone-specific formulations, and one-stop supply of complete sets (including resin or magnesite Frankfurt blocks).

FAQ
Some questions maybe you would like to know
Q: What is the service life of metal bond diamond frankfurt?
A: Tested under standard 20mm marble slab with full circulating water cooling: Coarse grit #24–#80: 35,000–45,000 ㎡ per block Medium rough grit #120–#320: 40,000–52,000 ㎡ per block Our upgraded high-density metal formula extends lifespan by 15%–20%. Service life will drop sharply if lacking cooling water or polishing fragile onyx stone.
Q: What’s the difference between metal, resin and magnesite frankfurt blocks?
A: Metal bond frankfurt delivers strongest cutting power and longest lifespan for rough slab leveling; resin bond frankfurt provides scratch-free mirror gloss for fine polishing; magnesite frankfurt is low-cost economical medium grinding abrasive for small marble factories. They must be matched together to complete a full marble polishing sequence.
Q: Can metal bond frankfurt polish luxury onyx stone?
A: Only for initial heavy calibration to remove thick epoxy and uneven layers. Do not use metal bond frankfurt for medium & fine polishing on onyx, its rigid metal matrix will leave permanent deep scratches and edge chipping. Soft resin bond frankfurt is recommended for onyx finishing.
Q: Does T105 metal bond frankfurt fit all Keda automatic marble polishing machines?
A: Yes, our universal T3/T105 horseshoe base with standard mounting holes matches all Keda 8/12/16/20-head marble continuous polishing lines directly. Custom non-standard sizes are supplied for bulk orders.
Q: What grit sequence uses metal bond frankfurt on marble line?
A: Standard full polishing flow: Metal bond frankfurt #36/#60/#120 → Magnesite frankfurt #240/#400 → Resin bond frankfurt #800/#1500/#3000 for final mirror gloss finishing. Do not skip grit sizes to avoid residual scratches on slab surface.
Q: What is the price range of metal bond diamond frankfurt blocks?
A: FOB China price for standard T105 horseshoe metal frankfurt varies by formula, segment thickness, water groove design and order quantity: Economy low-grade version: US$12–$16 per piece for bulk orders over 50pcs Standard universal grade (100% diamond concentration for marble): US$17–$24 per piece Upgraded heavy-duty type with water groove & thick segment: US$25–$32 per piece Custom special formula & OEM private label frankfurt: US$33–$42 per piece
Q: Why metal bond frankfurt costs more than magnesite frankfurt?
A: Metal bond frankfurt adopts high-cost copper-cobalt metal powder and high-temperature sintering craft, with high-content industrial diamond inside. Its service life is 15~20 times longer than magnesite frankfurt, greatly cutting downtime and total abrasive cost for large marble production lines.
Q: When should I choose metal bond frankfurt instead of resin or magnesite frankfurt?
A: Choose metal bond frankfurt if you need strong cutting power and ultra-long service life for rough leveling of thick marble slabs. It is the best choice for mass production lines with large material removal volume.
Q: What is the service life of metal bond diamond frankfurt blocks?
A: Lifespan depends on grit, marble hardness and cooling water supply, tested on standard 20mm marble slabs with full circulating water cooling: Coarse grit #24–#80: 35,000–48,000 square meters per piece Medium rough grit #120–#320: 38,000–55,000 square meters per piece Our upgraded high-cobalt metal formula extends service life by 15%–20% compared with ordinary metal frankfurt. Service life will drop sharply without enough cooling water or polishing hard repaired marble & terrazzo.
