The Qpol 250 A1/A2-ECO are single or twin wheel grinding and polishing machines for the materialographic laboratory, suitable for working wheels Ø 200/250 mm.
The machines are conveniently operated by a 4.3 „touch screen. The new holder for the working wheel (single-disc design) enables materialographic sample preparation without carrier disc without compromising performance. The control software allows to edit and save up to 200 preparation methods, protected by a user account management. The process of the current preparation is visualized by a status bar. It is possible to select an additional acoustic signal at the end of each preparation step in the service menu.
Pressure, speed and direction of rotation (head and working disc) are adjustable. A spin cycle function (Cleaning Boost) helps to spin dry the grinding and polishing medium at 750 rpm at the end of the preparation process within 3 seconds.
