What Are Metal-Bonded Diamond Fickert Abrasive Blocks?

Metal-bonded Diamond Fickert abrasive blocks utilize a metal powder matrix as a bonding agent to consolidate diamond abrasives. Designed for use with automated stone polishing machines, these block-shaped tools are employed for the coarse and medium-grade grinding and leveling of stone slabs.

Manufactured through a process of pressing and sintering diamond abrasives combined with metal bonding agents, they feature an integrated mounting base and are assembled in sets onto polishing heads. They are specifically engineered for grinding large slabs of granite, marble, and quartz stone.

In daily professional practice, these tools are also commonly referred to simply as "diamond grinding blocks, diamond fickert, diamond abrasive." In daily work, Resin-bonded Diamond Fickert Abrasive Blocks are referred to as resin grinding blocks , resin fickertor resin Abrasive,

• Surface Leveling and Thickness Calibration: Correcting surface height discrepancies and standardizing the overall slab thickness.
• Removal of Surface Imperfections: Eliminating saw marks, rough quarry skins, surface damage, and old coatings.
• Gradual Surface Refinement: Progressively reducing scratches from coarse to fine grades to regularize the slab's surface texture.
• Shaping and Edge Trimming: Trimming slab edges and shaping irregular or contoured profiles.
• Pre-Polishing Surface Preparation: Creating a flat, smooth base surface to pave the way for subsequent high-gloss polishing.
• Stone Restoration and Maintenance: Grinding down aged surfaces to restore the stone's original appearance and texture.

• 30# / 40#: Coarse grinding-rapid leveling, removal of quarry marks, and initial thickness calibration of large slabs.
• 60# / 80#: Medium-coarse grinding-eliminating deep scratches left by coarse grinding and regularizing the slab surface.
• 120# / 150#: Medium grinding-refining the surface texture and preparing the base for polishing.
• 200# / 300#: Fine grinding-attenuating scratches and enhancing the surface's smoothness and fineness.
• 400# and above: Fine grinding pretreatment-serving as a transitional step leading into the final polishing process.

Applicable Stone Types
Primarily Hard Stones: Granite, quartz stone, engineered stone, basalt, thick-gauge hard marble, and engineered large slabs.

Inapplicable Materials / Conditions
Soft marble, travertine, and other stones prone to scratching; fine-grade polishing or mirror-finish processing; and light grinding of thin slabs.

Manufacturing Process for Metal-Bonded Diamond Fickert Abrasive Blocks (7 Major Steps)

1. Batching and Weighing (Precision: ±0.1%)
2. Mixing (Critical step: Preventing segregation)
3. Cold Pressing (Pre-forming)
4. Hot Pressing & Sintering (Core process; determines service life and sharpness)
5. Post-processing (Ensuring precision and aesthetic finish)
6. Base Welding (Abrasive block + Aluminum base)
7. Inspection and Packaging

(Workers are connecting the sintered diamond abrasive layer and aluminum base together)
