What your metallography lab actually checks
Deformation-free, repeatable surfaces
Adjustable force, speed and direction plus 200 saved methods mean the final surface is set by a recipe, not by feel — so porosity counts and grain analysis on AM cross-sections repeat operator to operator, run to run.
An applications engineer on the line
Method setup, consumable selection and troubleshooting from engineers who run sample prep and materials characterization in-house. Sub-4h reply, NDA standard.
The QATM QPOL 250 A2-ECO is a double-wheel grinding and polishing machine for the metallographic laboratory, suitable for working wheels Ø 200/250 mm. A 4.3″ touch screen, 200 stored methods and fully adjustable pressure, speed and rotation make reproducible sample prep straightforward.
Why labs choose the QPOL 250 A2-ECO
Reproducible manual grinding and polishing with saved methods.
200 saved methods
Edit and store up to 200 preparation methods, protected by user-account management — every operator repeats the same recipe.
Full parameter control
Pressure, speed and direction of rotation (head and working disc) are all adjustable to the material.
Two wheels ready
Two working wheels keep grinding and polishing set up at once — no compromise on performance.
Cleaning Boost
A spin cycle dries the grinding/polishing medium at 750 rpm in about three seconds at the end of the run.
