Customized auto-feed and clamping accessories was used during the cutting process and a customized specimen holder reduced preparation time for the following hardness test. The complete process consisting of:</p>\n<ul>\n<li>Cutting with a modified Axitom-5 using an automatic feed and clamping system</li>\n<li>Grinding and polishing with AbraPlan-30 and AbraPol-30 allowing for simultaneous preparation of 6 differently shaped specimens in customized specimen holder</li>\n<li>A fully automated CHD-measurement of 15 indentations with Duramin-40AC1</li>\n</ul>\n<p>Tell us who you are and you may download a materialographic solution report of one of our many method solutions.
