In daily operations, metal-bond Diamond Fickert Abrasives are typically used for coarse and medium grinding, while resin-bond Diamond Fickert Abrasives are employed for fine grinding and polishing.
In actual practice, operators adjust their selection of Diamond Fickert abrasive grit sizes based on the specific type of stone, the machinery being used, and the specific polishing requirements of the project.
Below, we provide a brief guide on how to select the appropriate grit sizes for both metal-bond and resin-bond Diamond Fickert abrasives.

I. Common Grit Sizes and Corresponding Processes for Metal-Bond Diamond Fickert Abrasives
- 30#/40#: Coarse Grinding - Rapid leveling, removal of rough-block marks, and thickness calibration for large slabs.
- 60#/80#: Medium-Coarse Grinding - Elimination of deep scratches left by coarse grinding and surface regularization.
- 120#/150#: Medium Grinding - Refinement of surface texture and preparation (priming) for the subsequent polishing stage.
- 200#/300#: Fine Grinding - Attenuation of scratches and enhancement of surface smoothness/delicacy.
- 400# and Above: Fine Grinding Pre-treatment - A transitional step bridging the grinding phase to the final polishing process.
Note:
- Hard Stones (e.g., Granite, Quartz, Basalt): Start with a grit range of 30#–80# as a priority, then proceed sequentially through finer grits.
- Soft Stones (e.g., Common Marble, Limestone): Starting with 60# grit is sufficient; avoid using overly coarse grits to prevent leaving deep, irreparable scratches.
- Standard Conventional Process: 40# → 80# → 150# → 300#
(Resin Bond Diamond Fickert Abrasive)
2 Common Grit Sizes and Corresponding Processes for Resin-Bond Diamond Fickert Abrasives
- 80#–120# (Coarse-to-Fine Transition):Used immediately after the coarse and medium grinding stages performed with metal-bond abrasives to eliminate deep scratches and initiate preliminary surface refinement. Primarily used for transitional grinding of entire slabs; not intended for final fine finishing.
- 150#–240# (Medium-Fine Grinding):The standard transitional grit range; smooths out medium-level surface textures to ensure a uniform and fine finish. This serves as the universal foundational stage for mass-produced slabs.
- 300#–400# (Fine Grinding):Significantly attenuates scratches and enhances surface smoothness, serving as the critical preparatory base for achieving a high-gloss polish. Commonly used for architectural project slabs and flooring tiles.
- 600#–800# (Fine Grinding / Soft Gloss):After grinding, the surface exhibits a gentle luster; this range is suitable for creating matte or soft-gloss finishes, and also serves as the final preparatory step prior to full polishing.
- 1000# and Above (Ultra-Fine Grinding / Semi-Polishing):Characterized by extremely shallow texture and a high degree of surface smoothness, this range is utilized for high-end decorative panels, countertops, and custom-shaped components, allowing for the direct achievement of a semi-gloss effect.
Note:
- Metal-Bond Abrasive Block Finishing → #150 → #300 → #600: This sequence ensures a seamless transition, resulting in a natural and smooth progression of surface textures.
- For the grinding and trimming of irregularly shaped panels or edges, priority should be given to medium-to-high grit sizes (#300+); this approach yields a more uniform surface texture and minimizes the risk of edge chipping.
