Overview
The WEIYEE P-2T Dual-Disk Precision Polishing Machine is an engineered solution for standardized mechanical sample preparation in metallurgical, materials science, and quality control laboratories. Designed around the principle of controlled abrasive planarization, it delivers reproducible surface finish on metallographic specimens through synchronized rotational motion of two independently operated polishing disks. Each disk rotates at a fixed speed of 1400 rpm—optimized to balance material removal rate and surface integrity across common polishing media (e.g., diamond suspensions, alumina slurries, and colloidal silica). The machine conforms to foundational requirements outlined in ASTM E3, ISO 16927, and GB/T 13298 for metallographic specimen preparation, supporting consistent microstructural analysis by optical microscopy, SEM, and hardness testing.
Key Features
- Dual-disk architecture with physically isolated drive systems ensures independent operation—enabling simultaneous polishing with different abrasives or lubricants without cross-contamination.
- 203 mm (8-inch) aluminum alloy polishing plates provide uniform torque transmission and thermal stability under prolonged operation; surface flatness tolerance ≤ 0.02 mm per disk.
- Fixed-speed motor design eliminates variable-frequency drive complexity, enhancing long-term reliability and reducing maintenance intervals typical in high-duty-cycle lab environments.
- Integrated splash guard and removable drip tray facilitate containment of polishing fluids and simplify cleaning between specimen batches.
- Ergonomic height-adjustable base accommodates standard laboratory workbenches (72–85 cm); non-slip rubber feet ensure positional stability during operation.
- Compliance with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for electromagnetic compatibility in shared lab infrastructure.
Sample Compatibility & Compliance
The P-2T supports preparation of specimens ranging from 10 mm to 50 mm in diameter—including embedded metallic alloys, ceramics, composites, and geological sections. Its dual-disk configuration allows concurrent processing of reference and test samples under identical mechanical conditions, improving inter-batch comparability. All wet-polishing protocols align with ISO 14487 for abrasive particle size distribution control and ASTM E407 for etchant compatibility verification. The unit meets CE marking requirements for machinery safety (2006/42/EC) and carries factory calibration documentation traceable to CNAS-accredited metrology labs in China.
Software & Data Management
As a benchtop mechanical instrument without integrated digital control, the P-2T operates without firmware or proprietary software. However, its fixed operational parameters (1400 rpm, 220 V / 50 Hz input) are fully compatible with laboratory-wide equipment management systems that log usage via external time-stamped power meters or IoT-enabled outlet modules. Maintenance logs, calibration records, and SOP adherence can be tracked within LIMS platforms compliant with ISO/IEC 17025 and FDA 21 CFR Part 11 when paired with audit-trail-capable electronic notebooks.
Applications
- Routine metallographic specimen finishing prior to microhardness testing (ASTM E384, ISO 6507).
- Preparation of cross-sections for failure analysis in aerospace and automotive component QA/QC workflows.
- Surface conditioning of sintered tungsten carbide, silicon nitride, and alumina substrates for coating adhesion evaluation.
- Standardized polishing of weld joint specimens per AWS B4.0 and EN ISO 17639 requirements.
- Supporting GLP-compliant histomorphometric studies where surface planarity directly affects image-based grain size quantification (ASTM E112).
FAQ
Is the P-2T suitable for automated integration into robotic sample prep lines?
No—the P-2T is a manually operated, fixed-speed unit without communication interfaces (e.g., RS-232, Ethernet, or Modbus). It is intended for standalone use in technician-supervised workflows.
Can the polishing disks be replaced with custom-diameter plates?
Only 203 mm (8″) disks are mechanically and dynamically balanced for this model; substitution with non-OEM plates voids warranty and compromises rotational stability.
Does the unit include polishing cloths or consumables?
No—polishing cloths, diamond suspensions, and lubricants must be selected and procured separately based on specimen material and desired finish grade.
What safety certifications does the P-2T carry?
It bears CE marking under the Machinery Directive 2006/42/EC and complies with GB 5226.1–2019 (Chinese national standard equivalent to IEC 60204-1) for electrical safety.
Is routine calibration required?
Speed calibration is not necessary due to fixed-ratio gearmotor design; however, annual verification of disk runout (≤ 0.03 mm TIR) and motor insulation resistance (> 1 MΩ @ 500 V DC) is recommended per ISO 17025 Clause 6.4.6.
