Automatic grinder and polisher for material sample preparation
Streamline your metallographic sample preparation with a machine that ensures consistent grinding, polishing, and etching, delivering reliable results every time.

The Qpol XL from ATM Qness GmbH is a robust, floor-standing automatic grinder and polisher designed to deliver consistent and high-quality metallographic specimen preparation. Leveraging a solid steel frame, stainless steel lining, and powerful motors, this machine excels in grinding and polishing metal samples for metallurgical analysis.
Key features include an intuitive software interface capable of storing up to 200 preparation methods and a force-controlled pressing system ranging from 50 to 750 N. Its modular dosing system ensures precise wetting of the working surface, while an automated cleaning boost reduces contamination risks.
Ideal for applications in metallurgy, material science, and manufacturing, the Qpol XL processes metallic microstructures, polished alloys, and etched metal samples with ease. Operating with a variable wheel speed of 50 to 600 rpm and a sample holder speed of 50 to 350 rpm, its versatility accommodates diverse material testing needs.
With safety at the forefront, a motorized acrylic safety hood and an integrated spiral rinsing system simplify maintenance and cleaning tasks. The Qpol XL’s adaptability and efficiency make it a superior choice for laboratories and industrial facilities prioritizing precision and operational control in their sample preparation processes.
