How to Choose<\/h2>\n<p><strong>How to choose abrasives<\/strong>: The specific application depends on the hardness of the workpiece material and your current actual process. like:<\/p>\n<ul>\n<li>Diamond: super cemented carbide, electronic materials, ceramics.<\/li>\n<li>Aluminum oxide: soft metal, plastic, glass, IC substrate, packaging materials, semiconductors and various electronic parts, printed circuit boards (PCB) and connectors.<\/li>\n<li>Silicon Carbide (SiC): Suitable for semiconductor materials (such as silicon wafers and gallium arsenide), electronic materials, superhard metals, ceramics, glass, and gemstones.<\/li>\n<li>Cerium Oxide (CeO\u2082): Used for optical glass (lenses, prisms, and other optical components), gemstones, ceramics, semiconductors (such as wafers), and cubic zirconia.<\/li>\n<\/ul>\n<p style=\"padding-left: 40px;\">(Note: The above applications are for reference only. The specific use should depend on the hardness of the workpiece material and your current process requirements.)<\/p>\n<p><strong>Grit size selection<\/strong>: The 3.0um (4000#) fine grinding disk facilitates a seamless progression from a preceding 6.0um (2400#) grinding stage to a subsequent 1.0um polishing stage, followed by a final, precision polishing step using a polishing cloth devoid of polishing slurry.<\/p>\n<p><strong>Usage instructions<\/strong>: Simply place the fine grinding disc directly onto the magnetic machine plate. No polishing cloth or additional abrasives (polishing liquid) are needed; you can begin fine grinding using tap water.<\/p>\n<h2>3. Precautions<\/h2>\n<ul>\n<li>For optimal flatness, avoid sticking any labels or similar items to the bottom of the disc to prevent affecting workpiece flatness.<\/li>\n<li>Ensure that the contact surface between the grinding disc and the machine is very flat, clean, and dry to avoid impacting the workpiece&#8217;s flatness.<\/li>\n<li>After use, carefully remove the pad, rinse with water, and let it air dry.<\/li>\n<li>Avoid bending or damaging the precision grinding disc.<\/li>\n<li>When installing or removing, do so carefully to avoid magnetic attraction pinching your hands.<\/li>\n<\/ul>\n<h2>4.
