PRODUCT ADVANTAGES

MODULAR CONSTRUCTION

Within the sturdy aluminium housing, it is possible to install 4 to 8 system work stations. Up to 11 different operations can be programmed and sequenced for a particular application. Options include pre-grinding, grinding and polishing as well as cleaning and drying in any combination.The Qpol 300BOT automatically proceeds from one step to the next, eliminating the manual, time-consuming task of cleaning each sample holder between steps. With its modular construction the Qpol 300BOT has a price-to-performance ratio that makes it a cost effective system even for lower volume labs.

GRINDING AND POLISHING STATIONS

The Qpol 300 BOT is constructed with stations for complete materialographic operations from planar grinding through intermediate steps and final polishing. All stations are integrated into the system. The grinding and polishing discs are fixed onto the working wheels by using a vacuum (Vacu-Jet System) or magnetic disc system. Each station can be configured for specific abrasive requirements. Water, diamond suspensions, diamond lubricant and oxide dispensing are fully integrated and controlled via programming. Grinding and polishing stations can also include fully automatic protective covers to maintain a clean work environment.

FEATURES

The sample holder racking system holds up to 12 sample holders. After starting the machine, the holders are taken out automatically for processing. After processing, the completed sample holders are returned to their original position with the polished surface facing upwards.

In the storage elevator, there are four compartments for disposable grinding discs, such as SiC paper. The vacuum exchange arm grips the pre-selected SiC paper and places it onto the wheel. The Vacu-Jet system then operates immediately, securing the disc to the plate automatically. When finished, the used grinding paper is discarded.

After final cleaning, a programmable warm air blower dries the samples with the polished side upwards. Then the dry samples are stored in the sample stack. The drying time is programmable.

The cleaning station enables a fully automatic cleaning of the sample. The multi-step cleaning is carried out with water, air and alcohol. Cleaning times and steps are completely adjustable as needed.

The high speed grinding station planes the surface of the sample very quickly using an abrasive stone. The fully enclosed stone has an integrated recirculation coolant system in the cabinet. SiC and Al2O3 grinding stones are kept flat by an automatic diamond dressing device with adjustable dressing depths and intervals.

The wearing surface of our standard grinding stone with glued carrier plate is 30 mm.

For diamond grinding disc applications, a cup-wheel with sample holder adaption is available for dressing the diamond surface in freely configurable intervals.

DATA TRANSFER

The QATM central lab is always looking for solutions for your problems. We can develop an optimum procedure for a particular sample and send it to you via data transfer. Acquired data can also be exchanged via an internal network. This enables reproducibility and comparison of procedures and parameters anywhere, anytime.

INDIVIDUALLY CONFIGURABLE

With the Qpol 300 bot, all preparation steps up to the analysis can be performed. It is individually configured so that maximum sample throughput can be achieved with minimum space requirements. To achieve this, we analyse and optimise all preparation steps for the specific application in advance and then configure the system to suit the specific application.

PRODUCT ADVANTAGES

• Rapid changeable polishing bowl with magnetic system
• Surface-Guard: reduces crystallization and corrosion of the specimen surface
• Automatic frequency control from 60-120 Hz, e.g. for mass variation
• Intuitive user interface and touch screen
• Pre-installed preparation methods and consumable list
• Low-noise operation, almost indefinite polishing time without supervision
• Exhaust connection plug (exhaust connection for enhanced user-friendliness and safety)
• Up to 200 custom preparation methods can be saved

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.

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.

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.
