Bench polishing grinder Qpol series

electricmanualergonomic

Overview
Robust and easy to operate, the Qpol M1 (single-wheel) and Qpol M2 (twin-wheel) are manual grinding and polishing machines designed for materialographic laboratories. They accept working wheels Ø200, 250 and 300 mm and feature a speed-controlled drive for processing a wide range of materials. The solid construction and low-vibration design deliver consistent preparation results.

Product advantages

• Easy to use: Integrated ergonomic touch panel displays process parameters and allows quick manual adjustments.
• Reproducible results: Adjustable timer and torque/contact pressure display support repeatable manual preparation steps.
• Automatable workflows: Compatible with the Qdoser GO automatic dosing system for two-handed polishing and precise diamond suspension dosing.

Durable and reliable
Machine body in welded aluminium construction with durable powder coating. Low-vibration design for smooth operation. Speed-controlled drive provides sufficient power for larger samples. Impact-resistant plastic tub offers corrosion resistance and easy cleaning.

Simple cleaning system
Single-disc layout enables easy removal of components and quick access. Splash guard ring and working wheel can be detached with minimal effort. Tub insert (plastic inlay) is replaceable or removable for cleaning residual abrasives and suspensions.

Sturdy, pull-out faucet
Accessible water supply for thorough cleaning of the work area and grinding tray. Cleaning Boost function removes residual liquid (dries at 750 rpm in about 3 seconds). Water valve activates automatically at the start and end of the process. Robust faucet with flexible hose extension.

Ergonomically shaped splash guard
User-friendly design reduces splashing and serves as a comfortable hand rest during longer procedures. Grip recesses allow replacement of grinding/polishing media even with the ring fitted.

Work safety
High operational safety from a generously sized bowl and loosely mounted splash guard ring. Small gap between guard and working wheel ensures safe operation. Emergency stop immediately halts all moving parts.

Option: Qdoser dosing systems
Optional semi-automatic or software-controlled dosing systems increase process flexibility.

• Qdoser GO: Fully automatic, software-controlled dispensing system with four removable/refillable bottles for reproducible dosing; optional magnetic stirring.
• Qdoser ONE: Dropper bottle for simple continuous dosing.

Optional magnetic stirrer
Magnetic stirrer keeps polishing agents homogeneous and prevents suspension settling for even particle distribution.

User interface
Integrated 7-inch industrial touchscreen with QATM user software. Intuitive menus, progress indicator, audible end-of-process signal, built-in timer and direct torque/contact pressure display for high reproducibility.

Consumables
QATM recommends matched grinding and polishing consumables (diamond suspensions, lubricants, fine-polishing agents) optimized for reproducible preparation results.
