Grinding & Polishing Machine


The Qpol 300 M2 is a manual, twin wheel grinding and polishing machine for separately controlled working wheels Ø 250/300 mm.

In the ergonomically integrated touch panel, all process parameters as well as convenient features for manual preparation are clearly displayed and can be easily changed at any time. All process parameters can be saved as a preparation method. The adjustable timer and the torque display for visualizing the current grinding pressure enable comfortable and reproducible manual preparation steps. The water valve is automatically switched on/off when the preparation starts or ends.

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 retrofitted with the Qpol Go automatic grinding and polishing head and combined with the Qdoser GO and Qdoser ONE manual dosing system. It therefore offers a high degree of flexibility and comfort during sample preparation.
