Automatic grinder and polisher for metallographic sample preparation
In metallographic laboratories, precise sample preparation is essential. Challenges include achieving a uniform finish, maintaining consistent pressure, and ensuring efficient cleaning after each use. Laboratories need a reliable system to handle these tasks efficiently.

Streamline metallographic sample preparation processes
The Qpol 300 A1-ECO+ from QATM is a versatile single-wheel system designed for grinding and polishing metallographic samples. It operates with a working wheel of Ø 250/300 mm, efficiently managed via a 4.3-inch touch screen. The single-disc design eliminates the need for carrier discs, optimizing performance and simplifying cleaning. Up to 200 preparation methods can be stored and managed with user accounts, allowing for personalized and repeatable processes. The grinding and polishing head features adjustable pressure, speed, and rotational direction settings, ensuring precise control over the preparation process. A spin cycle (Cleaning Boost) dries the medium at 750 rpm in just 3 seconds. The system can be paired with the Qdoser ECO and Qdoser ONE dosing systems for added flexibility. Robust and user-friendly, this machine is ideal for metallographic laboratories needing reliable sample preparation.
