Sample preparation grinding polishing machine Qpol XL

metallographic samplefor floorlapping

Introduction
High sample throughput with maximum process reliability: the Qpol XL is a floor‑standing grinding and polishing machine designed for defined material removal and consistent sample preparation. Integrated load cell and motorized force control enable reproducible results. The intuitive software supports professional user management and storage of up to 200 preparation methods.

Product Advantages

• Working discs Ø 300 / 350 mm
• Drive spindle 2.2 kW – polishing head up to 1.1 kW
• Electronic force control (50–750 N)
• Modular dosing system with up to 6 vessels and optional magnetic stirrer
• Motorized swivelling dosing arm for uniform wetting of the working disc
• Spin cycle function for the working disc (Cleaning Boost)
• Automated safety hood for operator protection
• Fast, easy and tool-free working disc change

Robust engineering - functional design
The Qpol XL features a solid steel frame, powder-coated enclosure and a stainless-steel lined working area to ensure mechanical stability and durable operation in industrial laboratories.

Removal measurement
Integrated system for precise measurement of removed material enables monitoring independent of operating time, sample geometry, material or hardness, supporting reproducible process control.

Convincing performance data
Drive power of the working wheel 2.2 kW (S1). Polishing head drive 0.75 kW (S1) or 1.1 kW (S3). Both working wheel and polishing head can run clockwise, counter-clockwise and in oscillating mode.
