The Qpol 250 A1-ECO is a single-wheel grinding and polishing machine for the metallographic laboratory, suitable for working wheels Ø 200/250 mm. The machine is conveniently operated by a 4.3 "touch screen.
The new holder for the working wheel (single-disc design) enables metallographic sample preparation without carrier disc and without compromising performance. The control software allows to edit and save up to 200 preparation methods, protected by a user account management.
Pressure, speed and direction of rotation (head and working disc) are adjustable. 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.
The robust grinding and polishing machine can be combined with the dosing system Qdoser ECO or Qdoser ONE and offers maximum flexibility for sample preparation and operating convenience.
The grinding & polishing head ECO exerts 5 - 80 N in single pressure and 20 - 350 N in central pressure mode. Up to 6 samples Ø 40 mm can be moved at variable speed with sample holders Ø 130 mm.
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 machine is operated and programmed via the 4.3“ touch screen. Preparation methods for sample preparation may be edited and saved. It is also possible to prepare samples manually.
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.
