Grinding & Polishing Machine Qpol PLUS 1 / PLUS 2

Make it easy. Make it automated.

The Qpol PLUS 1 and PLUS 2 are automatic, single wheel or twin wheel grinding and polishing machines that can operate using either single or central pressure. They are suitable for working wheels with a diameter of 200/250/300 mm. The high-performance PLUS head also allows the use of large sample holders with diameters up to 185 mm (central pressure).

Product Advantages

Automated processes: High-removal grinding/polishing, variable dosing of diamond suspensions/lubricants, contact pressure, speed control, and the direction of rotation (in-phase/out-of-phase) for the polishing head and working wheel are all variable and freely adjustable.
High flexibility: The L sample holder allows for the use of very large samples.
High reproducibility: Automatic sample preparation methods can be customized, and up to 200 preparation methods—protected by user account management—can be edited and saved. Grinding and polishing results remain consistent even when the process is repeated.

High throughput, large samples and excellent reproducibility Plus grinding / polishing head

The PLUS grinding and polishing head delivers a contact pressure of 5–80 N in single pressure mode and 20–350 N in central pressure mode. Up to 6 samples with a diameter of 50 mm can be prepared at variable speeds using sample holders with a diameter of 160 mm, either in the same or opposite directions. In addition, thanks to the L-type sample holders, central-pressure sample holders with a diameter of up to 185 mm can also be used.

Reproducible results through automatic grinding and polishing
Easy to move thanks to recessed handles with integrated push buttons
Easy sample holder replacement thanks to ample clearance from the work surface

High process flexibility Qdoser dosing systems

The fully automatic, software-controlled Qdoser dosing system speeds up the grinding and polishing processes in the materialographic laboratory and is compatible with the QPol M, GO, and PLUS series, as well as the QPol PRO. Four screw-top 500-ml glass bottles can be filled with QPREP diamond suspensions, QPREP lubricants (diamond lubricants), and/or QPREP fine-polishing suspensions through a separate opening in the lid. The suspension storage bottles are easily removable, making them simple to clean. A backflush function keeps the connecting hoses clean.

Optimized filling and dosing

The suspension storage bottles can be removed at any time and refilled in a way that is optimized for application, e.g., with:

Qdoser PLUS: 3x diamond suspensions/lubricant and 1x fine polishing suspension (optional upgrade to a 1-liter bottle for fine polishing suspension)
Qdoser GO: 4x Dia-COMPLETE diamond suspensions

Option: Magnetic stirrer

A magnetic stirrer is available as an option for stirring the polishing agents to achieve excellent preparation results

The integrated magnetic stirrer prevents the suspension from settling
