{"id":200,"count":0,"description":"Metallographic sample preparation is a sequential chain of processes whose quality determines whether microstructure analysis and hardness testing will give a reliable result. The steps: <strong>abrasive cutting<\/strong> (removing a sample from the part without thermal or deformation damage) \u2192 <strong>hot mounting<\/strong> in resin, so the sample is easy to hold and grind \u2192 <strong>grinding<\/strong> (planar and fine grinding with SiC paper or diamond discs) \u2192 <strong>polishing<\/strong> (diamond suspensions, oxide suspensions, vibratory polishing) \u2192 <strong>etching<\/strong> (chemical or electrolytic, to reveal the microstructure) \u2192 <strong>microscopy and hardness testing<\/strong>. QATM (Verder Scientific group, Germany) manufactures equipment and consumables for this entire chain \u2013 from benchtop laboratory instruments to fully automated robotic lines.\r\n<strong>Intended for:<\/strong> materials science and quality laboratories, foundries, heat treatment and welding companies (macro sections of welds according to DIN EN ISO 5817), quality departments in the automotive and aerospace industries, universities and research institutes, electronics (PCB) and coating analysis.\r\nHow to choose:\r\n\r\n<strong>Benchtop vs floor-standing equipment<\/strong> \u2013 depending on the maximum sample diameter (benchtop cut-off machines up to ~\u00d8135 mm, floor-standing up to \u00d8244 mm) and the cut-off wheel diameter.\r\n<strong>Manual vs automatic<\/strong> \u2013 manual suits low sample volumes and training; automatic (with force control and program memory) ensures reproducibility and allows unattended operation.\r\n<strong>Sample size and quantity<\/strong> \u2013 mounting mould diameter (\u00d825\u201350 mm), sample holder capacity (e.g. 6\u00d7\u00d840 mm or 6\u00d7\u00d850 mm), one or two working wheels.\r\n<strong>Material<\/strong> \u2013 hard materials and high loads require a more powerful drive and a pulse cutting mode.\r\n\r\nIn your enquiry please state: the materials to be examined (steel, Al, Cu, hard metals, ceramics, PCB), typical sample dimensions and number per day, the desired level of automation, the available power supply (1 or 3 phase), water\/compressed air availability, and whether consumables are needed (cut-off wheels, resins, grinding paper, diamond suspensions).","link":"https:\/\/m-technologijos.lt\/en\/equipment\/metallography\/","name":"Metallography","slug":"metallography","taxonomy":"category","parent":0,"meta":[],"z_taxonomy_image_url":"https:\/\/m-technologijos.lt\/wp-content\/uploads\/2026\/10\/main_qcut150A-t2ywxrsnab7a077-1.png","_links":{"self":[{"href":"https:\/\/m-technologijos.lt\/en\/wp-json\/wp\/v2\/categories\/200","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/m-technologijos.lt\/en\/wp-json\/wp\/v2\/categories"}],"about":[{"href":"https:\/\/m-technologijos.lt\/en\/wp-json\/wp\/v2\/taxonomies\/category"}],"wp:post_type":[{"href":"https:\/\/m-technologijos.lt\/en\/wp-json\/wp\/v2\/posts?categories=200"},{"href":"https:\/\/m-technologijos.lt\/en\/wp-json\/wp\/v2\/products?categories=200"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
