Grinding and Polishing Machine: Qpol 250 A1 ECO

QATM has introduced a single-wheel grinding and polishing machine called Qpol 250 A1 ECO for working wheels Ø 200/250 mm. The machine can be easily operated by using a 4.3″ touch screen.

The new holder developed for the working wheel (single-disc design) allows for operation without using any carrier disc and without affecting the performance. The control software permits editing and saving of up to 200 preparation techniques protected by user account management.

The direction of rotation, speed, and pressure of both the head and working disk can be adjusted. Using a spin-cycle function (Cleaning Boost), the grinding and polishing medium can be spin-dried at 750 rpm towards the end of the preparation process in less than 3 seconds.

The powerful machine can be equipped with the dosing system Qdoser ECO, providing the highest flexibility and operating convenience for sample preparation.
