This latest machine prepares effective metallographic samples through pre-grinding and pre-polishing. The grinding-disc speed of 100 to 1000 rpm is microprocessor-controlled, with a digital tube display. It offers efficient grinding and polishing with an airtight shaft and a quick-adjustment grinding device, and works in both automatic and manual modes within a timed metallographic-preparation system.
