Grinding & Polishing Machine


The Qpol 250 M2 is a manual, double-wheel grinding and polishing machine for working wheels Ø 200/250 mm.

The start / stop button with illuminated status display and the rotary switch with scale and integrated boost button allow for intuitive operation.
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 and then turns off the device.

The particularly strong, speed-controlled drive makes this model suitable for all preparation steps and materials. In addition, the working disc can be operated in clockwise / counter-clockwise rotation.
The impact-resistant plastic bowl, the powder-coated aluminium housing and the high-quality components inside the device are the basis for smooth running and best preparation results.

The robust device can be combined with the manual dosing system TOPAS M and thus offers a high degree of flexibility for sample preparation and operating convenience.
