Grinding and polishing is the final stage in the sample preparation process and consists of several steps. Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformation-free, scratch-free and highly reflective sample surface. The sample may need to be examined, either etched or unetched, to reveal the microstructure of the material. It frequently happens that contrasts in the material are only visible after a successful etching step.
Metallographic grinding and polishing machines consist of grinders, sanders, polishers, grinder-polishers and other equipment made for metal, composite, ceramic, mineral, and material surface preparation uses. This equipment is used to make planar, polished surface letting you do materials analysis using many techniques such as spectrometry, hardness, microscopy, nanoindentation, and other methods.
Many metallographic grinders, polishers or grinder-polishers have been designed to hold a metal alloy or material sample fixed in a resin mount. You can use some grinding and polishing machines to handle complete, partial, or sectioned samples having an irregular shape for requirements where grain flow, manufacturing imperfection, or other attributes have to be examined for the sample.
Quality metallographic research machines employ a series of coarse grit to very fine grit abrasive equipment. You can use coarse grit abrasive discs, abrasive belts, abrasive stones, and grinding wheels to rough grind the object and expose the object within the mount. After you have completed the course grind, you can use wet grinding having a series of finer grit abrasive discs to refine the surface finish. Lastly, polishing is finished with abrasive pastes, abrasive slurries, polishing compounds with a polishing cloth. Apart from that, you can finally polish some alloy samples using an electropolisher. We supply many inventive grinder machines and planar grinder machine.
Dutco Tennant LLC provides Disc polishing machines which are widely used for polishing the metallography samples for Microscopic research to examine various metal structures. Disc Polishing Machines can finely polish samples to give a smooth and mirror-like appearance to enable correct metallographic explanation. Polished, smooth surface is important for ensuing precise metallographic elucidation. These machines have polishing discs which are fixed on the shaft and locked by a nut.
