The Grinding & Polishing Machine Qpol 250 M1 (SAPHIR 250 M1) is a manual, single-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.

The automatic dosing system Qdoser GO is universally suitable for use with all manual grinders. Four 500 ml glass bottles with screw caps hold 3 x suspension and 1 x lubricant or 4 x Dia-Complete and can be filled via a separate lid. They are easily removed for cleaning.

The holder for dosing nozzles for manual dosage may be freely positioned on the machine. The dosage interval can be variably set via the control panel. The backflushing function keeps the hoses clean.
