Description

QPOL 250 A2-ECO (Saphir 250 A2-Eco)

Grinding & Polishing Machine

 

The QPOL 250 A2-ECO is a double wheel grinding and polishing machine for working wheels Ø 200/250 mm which is conveniently operated by a 4.3 “touch screen.

The new holder for the working wheel (single-disc design) enables operation 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.

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.

The robust machine can be combined with the dosing system TOPAS ECO and offers maximum flexibility for sample preparation and operating convenience.
