OPTIONAL DOSING UNIT QDOSER ECO / ONE

The ECO grinding & polishing head with adjustable swivelling limits is equipped with recessed grips on both sides and integrated buttons for easy swivelling and adjustment. A large gap between the working surface and the polishing head ensures convenient changing of the sample holder.

After removal of the splash protection ring, the working wheel is freely accessible. The wheel is automatically arrested when placed on the new mounting system. On lifting the wheel, all parts below are accessible for easy cleaning.

The ECO polishing head is equipped with LED illumination of the working area and a holder for the nozzles of the Qdoser ECO dosing system. Water is supplied automatically via the head.

QATM offers a wide selection of standard sample holders in various diameters and for different applications and machines. Samples with unusual dimensions can be clamped with the help of special design sample holders.

The automatic grinders and polishers can be combined with the fully automatic dosing system Qdoser ECO or the manual dosing solution Qdoser One, thus offering a high degree of flexibility for sample preparation and ease of use.

DOSING UNITS QDOSER ECO / QDOSER ECO+

The Qdoser ECO and Qdoser ECO+ fully automatic dosing units speed up grinding and polishing processes in the materialographic laboratory and are designed for use with the automatic grinding machines of the Qpol 250/300 A series. 4 screwable 500 ml glass bottles can hold diamond suspensions, lubricant or final polishing suspensions and can be filled through a separate lid, even during operation. They are quickly removed for easy cleaning.
The dosing nozzles are easily attached to the grinding and polishing head. The dosing is controlled fully automatically by the software of the Qpol devices. A backflushing function keeps the hoses clean.
