Vibratory polishing newly discovered
The vibratory polishing device Qpol Vibro is designed for the virtually deformation-free preparation of specimen surfaces. It is ideal for further characterizations, e.g. EBSD (electron backscatter diffraction), AFM analysis and nanoindentation or micro hardness testing.
With a diameter of Ø = 308 mm the large bowl provides sufficient space for polishing of completely filled sample holders, large specimens, as well as for simultaneously polishing up to 21 specimens. Held by strong magnets the polishing bowl can be easily removed by pressing a button and exchanged by simply putting it back into the device – the magnetic forces will do their job.
The clamping ring protects the edge of the polishing cloth to ensure a long service life. In addition, the ring delimits the polishing area and enables the sample holders to move evenly. The bowl is designed for the use of polishing cloths on magnetic systems. Consequently, the cloth is quickly and easily removed.

Vibratory Polisher Qpol Vibro Benefits
The Qpol Vibro offers silent operation based on its robust, high-quality design, innovative vibratory transmission angle, and vibrational motor with oscillation compensation. It may run for hours without any noticeable noise development. The oscillation compensation of the vibrational motor prevents the vibrations from being transmitted to the machine case or bench, thus ensuring silent operation of the Qpol Vibro. The exhaust connection plug may be connected to an external exhaust system to safely discharge moisture or gases, thus providing a safe working environment for the operator.
The transparent, soft-closing hinged hood shows the premium quality of QATM machines and devices. It protects the suspension and specimens from contamination for achieving best preparation results. The Qpol Vibro offers a wealth of features but is still compact and lightweight – with a weight of only 45 kg it is very suitable as a bench top device.
Polishing – 3 easy steps
Setting up the polishing bowl
Inserting the mounted sample
Filling in the suspension

Simply clever Newly designed user interface
The innovative design of the Qpol Vibro software provides intuitive and user-friendly operation. 15 preparation methods for various materials are pre-installed, together with the appropriate consumables. The Qpol Vibro offers storage of up to 200 customized methods both on the device or on USB, allowing a transfer of methods from one device to another. These may be programmed without any restriction in duration or in vibration intensity. The device may be operated in manual or automatic mode. The selectively choosable alert function (timer) informs the operator that a program has ended. QATM invented a special operating mode to protect the prepared surface after preparation has finished: the Surface-Guard preserves the high quality of the prepared surface by preventing e.g. corrosion.
The Qpol Vibro is equipped with automatic frequency control which optimizes the oscillation frequency depending on the specific load of the bowl. The Qpol Vibro may be operated without supervision and almost without time-limit. This yields best polishing results and gives the user time for other tasks.

Vibratory Polisher Qpol Vibro Tips & Tricks
- For recurring polishing processes of different materials, simply use a different polishing bowl for each material.
- Additional weights should be used for hard specimen materials or low mass materials. The number of weights depends on the material hardness and the specimen size.
- How to improve your preparation?
Start directly after the last step of QATM’s standard preparation methods and choose one of the polishing methods for a particular material pre- installed in the Qpol Vibro. - We recommend to first grind and polish your specimens, e.g. according to the QATM standardized preparation methods. Vibratory polishing is the next step in the process.
