Manual grinder polisher for metallographic sample preparation
Achieve precise metallographic sample preparation with a versatile manual grinder and polisher, designed to handle all materials and preparation steps with intuitive controls and robust construction.

The Qpol 250 M2 from ATM Qness GmbH is a manual double-wheel grinder and polisher specifically designed for precise metallographic and materialographic sample preparation. This equipment stands out with its robust, speed-controlled drive that accommodates various preparation steps for different materials. The manual operation model uses a spin cycle function (Cleaning Boost) that efficiently dries the grinding and polishing medium at 750 rpm, enhancing operational convenience. It supports both clockwise and counter-clockwise rotation of its Ø 200/250 mm wheels, making it versatile for handling diverse specimen types. While commonly applied in metallurgy, material science, and quality control laboratories, the machine is adaptable with optional dosing systems like Qdoser GO or Qdoser ONE, allowing for consistent and precise application of suspensions and lubricants. Built with a powder-coated aluminum housing and impact-resistant plastic bowl, the Qpol 250 M2 ensures durability and high resistance to wear, reducing maintenance requirements. This grinder and polisher is well-suited for environments demanding meticulous sample processing, delivering polished metal specimens for metallurgical analysis, research, or quality testing.
