Overview
The QATM Qpol 30 is a compact, manually operated grinding and polishing unit engineered for precision sample preparation in metallurgical, materials science, and failure analysis laboratories. Unlike automated or motorized benchtop grinders, the Qpol 30 employs a dual-micromotor control architecture coupled with an integrated planetary gear reduction system—delivering high torque at low rotational speeds while maintaining exceptional speed stability across its full 1,000–40,000 rpm range. Its 30 mm platen diameter is optimized for small-area surface finishing of embedded metallographic specimens, thin-sectioned ceramics, semiconductor wafers, and coated substrates where localized, operator-controlled material removal is critical. Designed in accordance with DIN EN ISO 15510 and ASTM E3-22 guidelines for metallographic specimen preparation, the Qpol 30 supports standardized sequential grinding and polishing protocols without requiring external power amplification or complex mounting fixtures.
Key Features
- Portable, hand-held ergonomic design with integrated control unit—no fixed bench installation required.
- Dual independent micromotors with gear-reduction transmission ensuring consistent torque delivery even below 3,000 rpm, minimizing specimen edge rounding and thermal distortion.
- Continuously variable speed control via precision potentiometer, calibrated and traceable to internal tachometric feedback for repeatable process replication.
- 30 mm aluminum alloy platen with concentric thread interface compatible with standard consumable discs (e.g., SiC papers, diamond-impregnated pads, alumina suspensions on cloth).
- Compact footprint (130 × 97 × 254 mm) and lightweight construction (~2.3 kg) enabling use in glove boxes, cleanrooms, field labs, or mobile analytical units.
- CE-compliant 230 V / 50–60 Hz input with reinforced insulation and thermal cut-off protection meeting IEC 61000-6-2 EMC immunity standards.
Sample Compatibility & Compliance
The Qpol 30 accommodates specimens up to 25 mm in diameter when mounted on standard metallographic holders (e.g., hot-pressed phenolic or epoxy mounts). It is routinely deployed for preparing cross-sections of solder joints, thermal barrier coatings, additive-manufactured alloys, and layered battery electrode materials. All mechanical interfaces conform to ISO 80000-1:2022 dimensional referencing conventions. The device supports GLP-aligned documentation workflows when paired with QATM’s optional digital logbook module (sold separately), enabling audit-ready timestamped records of speed settings, duration, and consumable lot numbers per specimen batch. While not FDA 21 CFR Part 11 certified as a standalone unit, it may be validated within a compliant QA/QC environment per ISO/IEC 17025:2017 requirements for testing and calibration laboratories.
Software & Data Management
The Qpol 30 operates as a hardware-only platform with no embedded firmware or onboard data storage. Speed selection and runtime are manually controlled; however, it integrates seamlessly into laboratory information management systems (LIMS) via analog tachometer output (0–10 V DC proportional to rpm) and optional RS-485 expansion module (QATM Part No. QPOL-RS485-ADD). This enables real-time logging of rotational parameters into third-party SCADA or ELN platforms for SOP-driven process traceability. Calibration certificates for speed accuracy (±1.5% of setpoint, NIST-traceable) are supplied with each unit and updated annually during factory recalibration service.
Applications
- Precision final polishing of TEM lamellae prior to ion milling.
- Controlled thinning of brittle intermetallic phases in Ni-based superalloys.
- Surface planarization of MEMS devices and microelectronic packaging substrates.
- Routine preparation of cross-sectional samples for SEM-EDS compositional mapping and EBSD crystallographic analysis.
- Research-scale development of novel abrasive slurries and pad chemistries under reproducible shear conditions.
FAQ
Is the Qpol 30 suitable for wet grinding applications?
Yes—its sealed motor housing and corrosion-resistant platen mount support aqueous coolant delivery via standard drip-feed nozzles. Always verify compatibility of consumables with coolant chemistry before operation.
Can multiple platens be mounted simultaneously?
No—the Qpol 30 is configured for single-platen operation only. Multi-platen configurations require the Qpol 50 or Qpol 100 series.
Does the unit include speed calibration documentation?
Yes—each shipment includes a factory-issued calibration report with uncertainty budget, traceable to PTB (Physikalisch-Technische Bundesanstalt) reference standards.
What maintenance intervals are recommended?
Gear reduction assembly lubrication and motor brush inspection are advised every 1,000 operating hours or biannually, whichever occurs first. Full service is available through authorized QATM service centers in Europe, North America, and APAC regions.
Is technical support available in English for international users?
Yes—QATM provides multilingual engineering support, including remote diagnostics and application consultation, with response SLAs defined per regional distributor agreement.
