Utilizing a diamond blade for re-sectioning and a cup grinding wheel for reducing to thin sections, this machine prioritizes precise control to deliver results that conventional sectioning and grinder-polisher equipment simply can’t. For optimal results, complement your PetroThin with Buehler’s high-performance diamond / CBN blades and cup grinding wheels for a solution that sets the standard. #### PetroThin Benefits High Quality Thin Sections - PetroBond apparatus simplifies sample mounting, preparing them for processing - Precision blade sections larger samples down to size, ready for grinding - Cup grinding wheel creates ultra-thin sections for detailed analysis Precise User Control - Precision micrometer facilitates gradual material removal, enabling consistent creation of thin sections - Vacuum pump arm quickly secures samples in place - Sample arm seamlessly moves between cutting and grinding positions Complement your PetroThin with the [PetroVue thin section viewer](https://shop.buehler.com/petrovue-thin-section-viewer). The PetroVue uses polarized light so users can easily monitor thickness and uniformity of the sample.
