Silicon Carbide Grinding Papers

Buehler’s CarbiMet^® & MicroCut^® Silicon Carbide grinding papers are the premier line of silicon carbide grinding papers offering efficient material removal and minimal surface damage. Our griding papers come in various grit sizes, micron sizes and diameters.

High Material Removal with Superior Surface Finish

CarbiMet grinding papers offer quick grinding times with minimal surface damage during the grinding process. Since there is less damage to remove, the amount of subsequent processing may possibly be reduced, saving valuable time in the preparation process.

Tightly controlled particle sizes ensures consistent scratch depths and patterns to prevent sample damage and rework.

Delicate Preparation

MicroCut grinding papers provide gentle material removal and superior surface finish when processing delicate or sensitive materials.

Quick Change-Overs

Apex® S backing allows for fast changeovers between grinding paper steps. Simply remove the previous paper and apply the next one without needing to remove any backings or liners.

Frequently Asked Questions

Why are there two numbers for the grit size?

Both the ANSI grit standard in the US and the FEPA grit standard in Europe relate to an average particle size, but use slightly different measurement methods. The ANSI size is succeeded by the term “grit” while he FEPA number is identified by a preceding “P”. A comparison chart is available at www.buehler.com.

How long should I use the paper for?

CarbiMet starts with fast material removal due to sharp abrasive grains. As the particles become blunt during use, the speed of material removal slows and the potential for sample damage increases. The rate of degradation depends on sample hardness, size, material, applied load, and the grit size being used. To optimize the preparation process and sample quality, we recommend using coarse grit papers for up to 5 minutes, intermediate grits for 2-5 minutes, and very fine grits for 2 minutes or less.

Why is my PSA backed paper difficult to remove from the platen?

The Pressure Sensitive Adhesive (PSA) becomes stronger with more pressure and longer time in use. Our CarbiMet products utilize an adhesive that sticks well on a wide variety of surfaces but is easy to remove. If the paper becomes difficult to remove, apply Release Agent to the platen prior to use, or use a MagnoPad Teflon coated carrier plate.

How do I refresh my Apex S surface?

The Apex S surface is designed to last hundreds of uses, but can degrade if excess debris becomes stuck to the surface. For cleaning normal debris, rotate the Apex S on a platen at 50rpm and wipe firmly with an ethanol soaked cloth. For cleaning heavily ingrained debris, use a firm silicon scraper (not hard plastic), lubricating the surface with ethanol then clean with a cloth. Do not use other solvents or detergents as this can reduce the lifetime of the Apex S surface.

How do I avoid air entrapment when applying CarbiMet S or CarbiMet PSA paper?

Begin by firmly applying one edge of the paper and work your way across the platen to push the air out.

How can I prevent embedding of SiC particles in very soft materials?

embedding can be prevented by using candle or paraffin wax. Rotate the CarbiMet paper on the platen at ~50rpm, coat the paper lightly with wax, and use as normal. The grinding rate will be reduced, but this will help to eliminate embedding problems.
