What is a Diamond Fickert Abrasive?
Diamond Fickert Abrasive Blocks are specialized, elongated rectangular abrasives designed for use on fully automatic continuous polishing lines for granite, engineered stone, artificial stone, luxury stone, terrazzo, and ceramic tiles. Featuring a distinctive elongated brick shape and a dovetail base, they can be securely mounted onto the polishing heads of continuous automatic lines. Commonly known as "Fickerts," they are compatible with automatic polishing machines from brands such as Keda, Breton, Simec, and Intermac (featuring 12, 16, or 20 heads). Equipped with a standardized locking base (made of aluminum or plastic), they are installed in rows on the polishing heads for the batch grinding and polishing of large stone slabs.
In terms of bonding agents, the main types of Fickert abrasives currently on the market include metal-bond, resin-bond, magnesite-bond, and composite-bond Diamond Fickert Abrasive Blocks.
Abrasive tools constructed by combining an abrasive layer—such as wool, sponge fiber, rubber, silicon carbide filaments, or diamond-impregnated nylon filaments—with a "Fickert" style base are often referred to as Fickert Abrasives or Fickert-style Polishing Abrasives. These are utilized on stone polishing production lines, primarily to achieve antique, matte, or mirror-like finishes on stone surfaces.
Standard Specifications
1. L140 (140mm length, 56mm width): Sometimes referred to as the "T1" abrasive block. This is a globally standardized model compatible with approximately 90% of stone processing facilities.
2. L130: Designed for small-scale, 8-head, low-speed, and simplified polishing lines.
3. L170 (170mm length): An extended model designed for heavy-duty, high-speed polishing lines and large slab processing. Sometimes referred to as the "T2" abrasive block.
4. Abrasive Layer Thickness: Metal-bond Fickert Abrasive Blocks: 15/20mm; Resin-bond Fickert Abrasive Blocks: 12/15mm; options available with diagonal water-cooling channels for heat dissipation.
Tip:
"L140" and "L170" do not represent the exact physical dimensions of the abrasive block itself; rather, they designate the product's compatibility with specific polishing production lines.
Core Components and Working Mechanism
Fickert-style Abrasive Blocks typically consist of an abrasive layer—comprising the abrasive media that provide grinding force and the bonding agent that supports them—attached to a base via screws or adhesive.
Industrial Diamond Abrasive Grains: These serve as the primary cutting medium. The grit size (ranging from 24# for coarse grinding to 320# for fine grinding, and up to 6000#–10000# for polishing) determines the depth of scratches, the rate of material removal, and the final polish quality.
Bonding Agent: Common types include metal bonds (based on cobalt, iron, or copper), resin bonds, magnesite bonds, and hybrid bonds combining metal and resin. The bonding agent’s role is to securely hold the abrasive grains while wearing down at a controlled rate. As the bond wears, fresh, sharp abrasive edges are continuously exposed to the stone surface. Additionally, the bonding material interacts chemically and physically with the stone surface during operation, helping to achieve and maintain a high-gloss or mirror-like finish.
Dovetail Base: This is a standard mechanical connection component (usually made of steel, aluminum, or rigid plastic) used to lock the abrasive block onto the rotating radial grinding heads of multi-head continuous polishing machines. It is typically attached to the abrasive layer via screws or adhesive.
Complete Processing Workflow
Taking Standard Granite Production Line as an example
1: Metal-bond diamond fickert abrasive (coarse grinding/leveling) →
2: Magnesite fickert abrasive (cost-effective intermediate step) →
3: Resin-bond diamond fickert abrasive (medium polishing / mirror-finish polishing)
the Four Major Categories of Fickert Abrasive
Classified by bond and abrasive
Metal Diamond Fickert
High-temperature sintering of copper-cobalt-iron alloy powder ensures large diamond particles are firmly embedded, resulting in exceptional rigidity and high retention strength.
After block sawing, the machine performs heavy-duty roughing and slab leveling, rapidly removing deep saw marks and surface irregularities;It ensures uniform slab thickness, thereby reducing the load on consumables during the subsequent polishing stage;It is suitable for high-hardness stones such as Black Galaxy, Indian Black, and high-density quartzite.
Resin Diamond Fickert
Hot-press cured using modified phenolic/epoxy resin and diamond micropowder, the matrix features inherent elastic cushioning; available in two formulations: a hard, general-purpose resin and a soft, elastic resin specifically designed for luxury stones.
Following the coarse grinding stage, this process refines the surface texture, eliminates fine scratches, and produces a high-mirror finish that determines the final stone's luster. The soft-resin version is suitable for processing marble and translucent onyx. It offers flexible polishing that yields a smooth surface free of deep scratches, achieving a gloss level of 90–100°; the friction generates only mild heat, preventing stone scorching or black burn marks on the surface.
Magnesite Fickert
Made from magnesium oxide and silicon carbide, these are intended only for low-cost, intermediate grinding; they have a very short lifespan (1,200–3,500 m² per disc) and a unit price of $2–$5. While suitable for intermediate use in small-to-medium workshops, long-term mass production results in significantly higher labor costs for disc replacement and creates substantial dust pollution.
Reference service life of magnesite-bonded Fickert abrasive blocks: The total operating time for a single block under normal, continuous use is 1.5–3.5 hours (with longer durations for finer grit sizes); this is only 1/15 to 1/25 of the lifespan of metal-bond diamond Fickerts (50–80 hours) or resin-bond diamond Fickerts (25–45 hours).
Sponge Fickert Polishing Block
Sponge fiber fickert polishing blocks are ultra-fine mirror finishing abrasives specially designed as the final buff stage for automatic granite, quartz stone and ceramic slab polishing lines. Made of composite nylon fiber & elastic sponge embedded with super-fine diamond grit, standard L140 base fits all Keda, Breton, Simec polishing machines.
It provides dual finishing effect: ultra-high mirror gloss up to 100–110° and soft antique matte surface, perfectly eliminating tiny orange peel marks left by resin fickert, no slab burning or permanent scratches on light-colored stone, quartz and fragile onyx.
FAQ
Q: What is the service life of resin bond diamond fickert?
A: Tested under standard 20mm granite slab with full water cooling: #120–#600 medium grit: 30,000–38,000 ㎡ per piece #800–#3000 fine & buff grit: 35,000–45,000 ㎡ per piece Custom upgraded resin formula extends lifespan by 15%–20%. Service life will drop obviously without enough cooling water.
Q: What’s the difference between resin and metal bond diamond fickert?
A: Metal bond fickert owns super strong cutting power and longest lifespan for rough slab leveling; resin bond fickert features flexible elastic matrix to produce scratch-free high-gloss finish for fine polishing. They must be matched together for a complete granite polishing sequence.
Q: Can resin fickert polish marble and onyx luxury stone?
A: Yes, we supply soft customized resin formula fickert specially for fragile marble, travertine and onyx. It polishes gently without deep scratches or edge chipping, ideal for luxury soft stone finishing.
Q: Does standard L140 resin fickert fit Keda automatic polishing machine?
A: Absolutely. Our universal L140 base with standard mounting holes matches all Keda 12/16/20-head granite polishing lines directly, no machine modification needed. Custom L130/L170 sizes are available for bulk orders.
Q: What grit sequence needs resin bond fickert on granite line?
A: Standard full polishing flow: Metal bond #30/#80 → Magnesite #240/#400 → Resin bond #800/#1500/#3000/Buff for final mirror gloss finishing. Do not skip grit sizes to avoid residual scratches on slab surface.
Q: Can I use metal fickert instead of resin fickert for mirror finishing?
A: No. Hard metal bond will leave deep permanent scratches on slabs, and cannot produce high-gloss mirror surface. Resin bond fickert is mandatory for final polishing.
Q: What is the application of sponge fiber fickert blocks?
A: They are the last buff polishing step for granite, engineered quartz, marble, ceramic large slabs and luxury onyx stone, to get ultra-clear mirror or soft antique matte finish. Not for rough grinding & scratch removal.
Q: Difference between sponge fiber fickert and resin bond fickert?
A: Resin fickert works for medium & fine grinding to remove medium scratches; sponge fiber fickert is only for final mirror buffing to achieve transparent, scratch-free high gloss surface with better heat dissipation performance.
Q: Why resin fickert is much cheaper than metal bond fickert?
A: Resin bond fickert adopts low-cost phenolic resin matrix without high-cost copper-cobalt metal powder and high-temperature sintering process. It is designed for fine polishing stage instead of heavy rough calibration, with moderate raw material cost, perfect for mirror finishing after medium grinding.
Q: What is the price range of resin bond diamond fickert blocks?
A: FOB China price for standard L140mm resin fickert depends on formula, segment thickness, grit and order quantity: Economy low-grade version: US$11.5–$14.5 per piece for bulk orders above 36pcs Standard universal grade (100% diamond concentration for granite): US$15–$22 per piece Upgraded premium soft resin for quartzite & onyx: US$23–$29 per piece Custom L130/L170 size & special OEM formula: US$30–$38 per piece
Q: How does magnesite fickert compare with metal/resin diamond fickert in lifespan?
A: Magnesite fickert has much shorter service life. Metal bond diamond fickert can reach 50,000–70,000㎡, resin diamond fickert 30,000–45,000㎡, around 15~25 times longer than magnesite. But magnesite fickert features ultra-low unit price and sharp grinding performance for medium grinding stage of standard granite.
Q: Can magnesium fickert work for hard quartzite & luxury stone?
A: Not recommended. It wears fast on high-density luxury stone, we suggest custom resin diamond fickert for quartzite and onyx.
