Manual twin wheel grinder for metallographic sample preparation
When preparing metallographic samples, achieving precise and reproducible results is essential. Traditional methods often lack the control needed to handle these delicate tasks effectively.

Manual grinding and polishing with adjustable parameters
The Qpol 300 M2 by QATM offers a dual-wheel, manual solution for metallographic sample preparation. Each working wheel, with a diameter of 250/300 mm, is operated independently, allowing for versatile material preparation. The user-friendly touch panel lets you easily adjust and save process parameters. The adjustable timer and torque display provide consistent results, while the automatic water valve and spin cycle function facilitate easy cleaning. Additionally, the unit supports clockwise and counter-clockwise rotation, offers variable speed control (30 – 600 rpm), and can be retrofitted with the Qpol Go automatic head and Qdoser systems for added flexibility.
