QATM Qpol 250A2-ECO Automatic Dual-Disc Grinding and Polishing System

Overview

The QATM Qpol 250A2-ECO is an automated dual-disc grinding and polishing system engineered for precision metallographic sample preparation in quality control laboratories, R&D facilities, and accredited testing institutions. Designed to replace manual or semi-automated workflows, it implements a controlled, repeatable material removal process based on mechanical abrasion and lubricated surface finishing—principally governed by defined pressure, rotational velocity, and directional torque applied across two independently driven platters. Its architecture supports standardized sequential preparation protocols per ISO 14577, ASTM E3, and EN 1071-3, ensuring traceability and reproducibility required for metallurgical analysis, failure investigation, and microstructural validation.

Key Features

• Automated dual-platter operation with independent speed and direction control for both grinding/polishing heads and platters (clockwise/counter-clockwise selection)
• Integrated high-speed dehydration spin cycle (750 rpm for 3 seconds) at process completion to rapidly remove residual slurry and coolant from abrasive media
• 4.3-inch capacitive touchscreen interface running QATM’s proprietary embedded control software, enabling intuitive method navigation and real-time parameter monitoring
• Capacity to store up to 200 user-defined preparation methods—including force profiles, time steps, rotation sequences, and media-specific parameters—with password-protected account management
• Tool-free platter mounting system (full-disk design) eliminating the need for carrier bases—reducing alignment errors and maintenance downtime
• Rugged aluminum housing with powder-coated finish and impact-resistant polymer inner basin for long-term chemical and mechanical durability
• Modular compatibility with QATM’s Qdoser ECO or Qdoser ONE liquid dosing systems for precise, programmable delivery of lubricants, coolants, or colloidal silica suspensions
• Ergonomic lift-assist mechanism for platter elevation—facilitating rapid basin access, cleaning, and residue removal without disassembly
• Energy-efficient LED illumination integrated into the operator-facing enclosure for consistent visual inspection during setup and post-process verification

Sample Compatibility & Compliance

The Qpol 250A2-ECO accommodates a broad spectrum of metallic and ceramic specimens—including ferrous and non-ferrous alloys, sintered metals, composites, and hard-brittle materials—across standard specimen diameters (25–50 mm) and thicknesses up to 35 mm. Its dual-platter configuration enables simultaneous coarse grinding on one station and fine polishing on the other, minimizing cross-contamination and inter-process handling. The system complies with CE marking requirements under the Machinery Directive 2006/42/EC and conforms to electrical safety standards IEC 61000-6-2/6-4. It supports GLP and GMP-aligned documentation practices through audit-trail-capable method logging and user-level access controls—critical for laboratories subject to ISO/IEC 17025 accreditation or FDA-regulated environments requiring 21 CFR Part 11–compliant electronic records.

Software & Data Management

The embedded QATM control software provides deterministic execution of multi-step preparation routines, each comprising up to six sequential stages with individually assignable parameters: platter/head speed, applied load (via pneumatic or mechanical actuation), rotation direction, dwell time, and dosing trigger points. All executed methods are timestamped and logged with operator ID, method name, and deviation flags (e.g., out-of-tolerance speed fluctuation or timeout). Export options include CSV-formatted logs compatible with LIMS integration. Firmware updates are performed via USB drive, ensuring version control and regulatory traceability without network dependency.

Applications

• Preparation of cross-sections for optical microscopy (OM) and scanning electron microscopy (SEM) analysis
• Surface planarization prior to hardness testing (Vickers, Knoop, Rockwell) per ASTM E92/E384
• Edge retention optimization in failure analysis of welded joints, castings, and additive-manufactured components
• Routine QC preparation of incoming raw materials and finished parts in automotive, aerospace, and power generation sectors
• Standardized polishing of coated systems (e.g., thermal barrier coatings, PVD/CVD layers) for interface integrity assessment

FAQ

Can the Qpol 250A2-ECO operate with both 200 mm and 250 mm platters interchangeably?
Yes—the system accepts either Ø 200 mm or Ø 250 mm platters using the same mounting interface; no hardware modification is required.
Is the dehydration spin function programmable or fixed?
It is fixed at 750 rpm for 3 seconds and initiates automatically upon method completion; it cannot be disabled or re-timed via user interface.
Does the system support external PC connectivity for remote monitoring?
No native Ethernet or Wi-Fi interface is included; data export is limited to USB-stick-based CSV logging.
What maintenance intervals are recommended for the drive belts and bearings?
QATM specifies 12-month preventive maintenance for belt tension verification and bearing lubrication—documented in the supplied service manual and aligned with ISO 13374 condition monitoring guidelines.
Are consumables such as platter backing pads and dosing tubing available through QATM-certified channels?
Yes—all consumables are OEM-specified and distributed globally through authorized QATM partners to ensure dimensional accuracy and chemical resistance compliance.
