electricindustrialergonomic

Introduction
Qpol GO 1 (single wheel) and Qpol GO 2 (twin wheel) are automatic grinding and polishing machines designed for metallographic sample preparation. They accept working wheels Ø 200, 250 or 300 mm and support single-pressure and central-pressure modes.

Product Advantages

• Automated process control: programmable dosing of diamond suspensions and lubricants, adjustable contact pressure, speed control and selectable rotation direction (in-phase/out-of-phase) between polishing head and working wheel.
• User interface: 7-inch industrial touchscreen with intuitive QATM software for recipe management and process monitoring.
• Reproducibility: up to 200 preparation methods can be saved per user account to ensure consistent results.

Durable and reliable construction
Welded aluminum machine body with industrial powder coat, low-vibration design and speed-controlled drive suitable for larger samples. Impact-resistant plastic tub for corrosion resistance and easy cleaning.

Grinding/polishing head with swivel bearings

• Adjustable swivel stops for simple positioning and handling.
• Recessed handles with integrated push buttons for unlocking and safe operation.
• Large clearance between head and work surface for easy sample holder changes.

Simple cleaning system

• Single-disc layout allows quick removal of components and easy access for cleaning.
• Removable splash guard ring and working wheel reduce setup and cleaning time.
• Replaceable plastic tub insert for fast removal of residues and abrasives.

Sturdy, pull-out faucet

• Flexible hose extension for thorough cleaning of the work area and tub.
• Cleaning Boost function removes residual liquid from media (dries at 750 rpm in approx. 3 seconds).
• Water valve activates automatically at the start and end of a preparation process.

Option: Qdoser dosing systems

• Qdoser GO: fully automatic, software-controlled dispenser with 4 removable/refillable bottles for reproducible dosing (optional magnetic stirring).
• Qdoser ONE: dropper bottle for manual continuous dosing.

Ergonomically shaped splash guard

• Reduces splashing and serves as a comfortable hand rest during longer procedures.
• Grip recesses permit replacement of media while the ring remains in place.

Intuitive operation

• Integrated 7-inch touchscreen running QATM software with clear menu structure and progress indicator.
• Built-in timer, direct display of torque/contact pressure and audible signal at process end.
• USB port for data transfer and software updates.

Grinding/polishing heads & safety

• Supports single-pressure and central-pressure operation modes.
• Two-hand operation for operator safety and emergency stop to halt all movements.

Consumables & process enhancements
QATM consumables are recommended for optimal results. Qdoser GO bottles (500 ml glass screw-top) accept diamond suspensions, lubricants or fine-polishing media; bottles are removable and easy to clean. Optional magnetic stirrer prevents settling for consistent dosing.
