Easy To Use Grinding and Polishing Solutions for Your Needs

The choice of Grinding and Polishing consumables has critical impact on the metallographic sample quality.

With premium Grinding and Polishing Consumables, Buehler is here to help you optimize metallography testing, delivering high quality sample preparation with efficiency and repeatability improvements for your process.

Buehler Consumables have been the technicians’ choice for easy to use Grinding and Polishing solutions.

Grinding Consumables

Buehler grinding consumables offer high material removal rate and minimal surface damage during the grinding process, saving valuable time in your sample preparation process.

Silicon Carbide Grinding Papers

For fast, single-use grinding solutions, Buehler’s CarbiMet® & MicroCut® silicon carbide grinding papers are available in 8-12″ [254-356mm] sizes with 3 backing options for your preferred application. These papers provide efficient material removal and minimal surface damage to meet any metallographic testing need while being easy to apply with no curling.

Diamond Grinding Discs

For fast, multi-use grinding solutions, Buehler’s range of diamond grinding discs are available in 8-12″ [254-356mm] sizes with either PSA or magnetic backing for your preferred application. The combination of extended lifetime, consistency and reduced waste makes Buehler’s diamond grinding discs the preferred choice for your process.

Polishing Consumables

Buehler’s premium performance polishing products are designed to give you a superior surface finish. Combine our polishing cloths with our industry leading MetaDi® Supreme or explore our specialty products for a complete solution. Experience the difference with Buehler.

Diamond Polishing Suspensions & Pastes

For superior polishing suspensions and pastes, Buehler offers MetaDi® solutions in both mono and polycrystalline diamond particle ranging from 45 down to 0.05 microns. Our diamond products ensure the best quality surface finish and consistency for your process. Also look for our extender and diamond/extender combo products.

Premium Polishing Cloths

Buehler’s large selection of premium performance cloths offer a variety of fabrics, weaves and naps for you to find the right cloth to achieve superior surface finish and reliable preparation results in the most efficient time, and are available in 8″ to 12″ [254-356mm] sizes. Pair your cloth with MetaDi® Supreme for a complete solution.

Final Polishing Suspensions & Powders

When your analysis require an excellent surface finish, Buehler’s alumina and colloidal silica suspensions and powders are available in various particle sizes as small a 0.02 microns. See the difference as these products remove the final layer of deformation that is often invisible to the naked eye.

Specialty Grinding & Polishing

Ideal for delicate applications such as optical fibers, microelectronics, petrographic samples, and more, Buehler’s UltraPrep™ diamond lapping films and FibrMet® abrasive discs feature polishing particles ranging from 30 down to 0.1 microns. Achieve exceptional flatness with minimal deformation to meet the needs your process demands.

Platen Systems for Grinding and Polishing Consumables

Learn about the differences between standard, Apex® S, and Magnetic platen systems to find the system that meets your needs for speed and ease of use.

SOLUTIONS To Common Issues

When a typical grinder polisher can’t give you the flatness or surface finish you require or if you have extremely limited space or work in hot cells, our specialty solutions are the answer you need.

Large Scratches

Large scratches remaining in the finer polishing stages may be a symptom of cross-contamination. Rinsing the specimen, specimen holder, and platen between steps can help clean out the larger diamond, reducing cross-contamination. If a specimen is cracked or porous, rinse in an ultrasonic bath for the minimum time required to rinse it clean. Extended ultrasonic cleaning time can damage the specimen. During the last 30 seconds of final polishing, stop applying additional suspension, replacing it with water to flush the cloth surface and rinse the specimen.

Relief

Relief is demonstrated by harder phases or constituents being left raised above the surface of the softer matrix. Prevent relief by reducing polish time, using a shorter napped cloth, or applying diamond paste rather than suspension.

Diamond Embedding

Embedding occurs when harder particles become engrained in softer material or cracks and voids. Using a more fixed abrasive, such as MetaDi Diamond Paste, or ultrasonic cleaning between stages can reduce the likelihood of embedding.

Smearing

Smearing is a superficial but significant form of damage that makes microstructural details less distinct, often caused by soft materials or poor lubrication. Smearing can be improved by using short napped cloths, vibratory polishing, or etching and then repeating the final polish.
