2026-06-12
Diamond flap discs, with their broad applicability across five major sectors—stone materials, construction materials, metal alloys, semiconductors, and composite materials—have become an essential tool for precision grinding in modern industry. By selecting the appropriate grit size and processing parameters based on the material being worked, the product’s performance advantages can be fully realized.
Diamond flap discs, featuring Mohs‑scale 10‑grade ultra‑hard abrasives and a multi‑layer flexible flap construction, deliver high‑efficiency grinding and precision surface finishing across five major material categories. This article provides a systematic overview of their comprehensive material application range, helping users make accurate selection decisions.
Five Major Categories of Applicable Materials
Recommended particle size by material
| Material Category | Recommended particle size range | Process Description |
|---|---|---|
| Natural Stone / Slab | #46–#80 Rough grinding → #200–#400 Fine grinding | Progress step by step through each process stage, avoiding skipping levels across different granularity scales. |
| Glass / Ceramics / Tiles | #120–#200 Trimming → #400 | It is recommended to perform wet grinding throughout the process to prevent thermal cracking. |
| Stainless steel / Titanium alloy | #60–#120 Deburring → #200–#400 Surface treatment | Maintain appropriate pressure to prevent workpiece overheating. |
| Cemented carbide / Tungsten steel | #60–#200 | We recommend sintered-type or high-concentration electroplating products. |
| Monocrystalline silicon / Silicon wafer | #400 | Fine granularity is required; wet grinding is preferred, with strict pressure control. |
| CFRP / GFRP | #80–#400 | An open abrasive structure is selected to prevent clogging. |
Precautions for Use
Grain size progresses in a stepwise manner. When performing multi‑step operations, it is recommended to proceed in the sequence of coarse → medium → fine, to avoid cross‑grain‑size machining that could compromise surface quality.
Wet grinding is preferred. When machining heat-sensitive materials such as glass, ceramics, and silicon wafers, it is recommended to use wet grinding throughout the process to ensure effective heat dissipation and extend tool life.
Apply moderate pressure : Allow the diamond abrasive to perform its cutting action naturally, avoiding excessive pressure that could cause abrasive grains to fall off or damage the workpiece.
Speed matching : Ensure that the product’s rated speed matches the equipment’s operating speed; do not operate at speeds exceeding the rated limit.
Material Compatibility Verification When machining ultra-hard materials such as cemented carbide and tungsten steel, it is recommended to use high-concentration or specially formulated products to achieve optimal grinding performance.
