This requires a precise cutting setup using well-chosen equipment and a cutoff wheel in order to end up with the desired sample in two halves, with a minimum of mechanical damage.</h2><figure><img src=\"/files/struers-file-ce8eb988dca05a4a8385caf2/sparkplug-sort-974x732_8bcb11d8.png\" alt=\"Sparkplug\" width=\"500\" height=\"376\" loading=\"lazy\">\n<figcaption>Sparkplug</figcaption>\n</figure>\n<h2>Solution:</h2>\n<p>A reproducible method for cutting a sparkplug was developed, consisting of:</p>\n<ul>\n<li>Clamping and positioning the sparkplug using a vertical clamping tool and a dedicated vise. </li>\n<li>Precision cutting with Secotom-50 to section the component exactly in the middle.</li>\n<li>A metal bonded diamond cutoff wheel with 0.6 mm thickness was used to achieve a minimum of mechanical damage and a very precise cut.</li>\n<li>A rotational speed of 2,200 rpm and a feed speed of 0.04 mm/s were used. A direct cut in the 85 mm length of the sparkplug was used, starting from the connector end towards the electrode end.</li>\n</ul>\n<p>Tell us who you are, and you may download a materialographic solution report of one of our many solution methods.
