The precision cutting, sectioning 2,250-2,300 um disk-shaped pellets from a small cylindrical piece is a challenging multi-step process. Optimization to a fast and accurate process eliminating the need for epoxy mounting is demonstrated in the solution.</h2><figure><img src=\"/files/struers-file-cbc50febd997263bd03999bd/silicon-big.jpg\" alt=\"Ultra Pure Silicon Challenge\" width=\"495\" height=\"500\" loading=\"lazy\">\n<figcaption>Ultra Pure Silicon Challenge</figcaption>\n</figure>\n<h2>Solution:</h2>\n<p>Twenty-four hours' curing time from the epoxy gluing process has been eliminated and thereby has also removed a challenging aligning procedure before cutting. Cost cutting has been acheived, as specialized graphite support is no longer needed. A 30-second fixation process in a specialized three-jaw chuck has replaced the epoxy gluing, which also minimizes health and safety issues.</p>\n<p><span>Tell us who you are, and you may download a materialographic solution report of one of our many solution methods.
