What your metallography lab actually checks
Identical prep, every specimen
Full automation of grinding, polishing, cleaning and drying across 4–8 stations means each AM specimen is processed exactly the same way — reproducibility you can defend in a QC audit, at production volume.
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 300 BOT, designed and developed by QATM, completely automates the grinding and polishing steps of specimen preparation — including cleaning and drying. Simple touch-screen controls access every parameter, so each specimen is processed identically and reproducibly, freeing bench space and staff for analysis.
Why labs choose the QPOL 300 BOT
