Overview
The W0505 Core Face Grinding Machine is a precision-engineered laboratory instrument designed specifically for the preparation of cylindrical rock core samples prior to petrophysical characterization. It operates on the principle of controlled abrasive grinding using a diamond-impregnated rotating wheel under continuous coolant lubrication, ensuring minimal thermal distortion and mechanical damage to the sample surface. This machine is essential in upstream geoscience laboratories, core analysis centers, and reservoir evaluation facilities where accurate measurement of porosity, permeability, compressibility, and acoustic velocity demands geometrically precise end faces—flatness within ±0.001″ (±25 µm) and parallelism between opposing surfaces within the same tolerance. Its rigid cast-iron base, vertically adjustable grinding head, and kinematically constrained sample clamping system collectively deliver repeatable surface finish and dimensional fidelity across heterogeneous lithologies including sandstone, carbonate, shale, and synthetic core plugs.
Key Features
- Universal core clamping mechanism accommodating cylindrical specimens from 0.5″ to 2.0″ (12.7–50.8 mm) in diameter, with quick-release lever actuation and radial preload adjustment for uniform contact pressure
- Diamond-bonded grinding wheel (150 mm diameter, 10 mm thickness) mounted on a high-stiffness spindle driven by a 0.55 kW, 3000 rpm induction motor with variable-speed control via integrated frequency inverter
- Integrated recirculating coolant system with stainless-steel reservoir (5 L capacity), submersible pump, filtration cartridge, and directed nozzle delivery to suppress dust generation and dissipate frictional heat
- Dual-mode operation: wet grinding (standard configuration) and dry grinding (with optional vacuum dust extraction interface compliant with IEC 60335-1 safety standards)
- Adjustable vertical feed mechanism with micrometer-scale depth graduation (0.01 mm resolution) and mechanical stop limit for consistent material removal per pass
- Robust aluminum alloy frame with vibration-dampening rubber feet and fully enclosed safety guard meeting EN ISO 13857 requirements for access distance to hazardous zones
Sample Compatibility & Compliance
The W0505 accepts standard NQ, HQ, BQ, and PQ-sized core plugs as defined by ASTM D4543 and ISO 14688-1, including both whole-round and trimmed half-core specimens. The clamping system accommodates irregular cross-sections up to 2″ diameter without requiring custom fixtures. All wet-grinding operations comply with OSHA 1910.132 (PPE requirements) and EU Directive 2006/42/EC (Machinery Directive). The coolant circuit is compatible with water-glycol mixtures and biocide-treated aqueous solutions used in petroleum core labs. Instrument design supports GLP-compliant workflows through traceable calibration records for wheel runout (≤0.02 mm TIR) and surface flatness verification using certified optical flats (ISO 10110-7).
Software & Data Management
While the W0505 operates as a standalone benchtop unit without embedded microprocessor control, it integrates seamlessly into digital lab infrastructure via optional accessories: a USB-connected digital depth gauge (0.001 mm resolution) with CSV export capability; a Bluetooth-enabled torque sensor for real-time clamping force monitoring; and an API-accessible log module that records operational timestamps, coolant temperature, and cumulative grinding duration—enabling audit-ready documentation aligned with FDA 21 CFR Part 11 electronic record requirements when paired with validated LIMS platforms.
Applications
- Preparation of core plugs for steady-state and unsteady-state permeability measurements (ASTM D2340, API RP 40)
- Surface conditioning prior to mercury intrusion porosimetry (ASTM D4404) and nuclear magnetic resonance (NMR) core analysis
- End-face finishing for triaxial compression testing (ISO 14688-2, ASTM D7012) to eliminate stress concentration artifacts
- Routine quality assurance of core plug geometry in contract laboratories serving E&P operators and service companies
- Research-grade sample prep for digital rock physics modeling where voxel-based boundary conditions depend on sub-50 µm surface deviation tolerances
FAQ
What core diameters does the W0505 support?
The universal clamping system accepts cylindrical rock cores ranging from 0.5 inches (12.7 mm) to 2.0 inches (50.8 mm) in diameter.
Is the grinding wheel replaceable, and what is its typical service life?
Yes—the 150 mm diamond wheel is field-replaceable using standard M14 threading; average service life exceeds 2,000 linear meters of granite-equivalent abrasion under recommended coolant flow and feed rates.
Can the machine be operated without coolant?
Dry grinding is supported only when equipped with the optional industrial vacuum extraction system rated at ≥120 m³/h airflow and fitted with HEPA H13 filtration per EN 1822-1.
Does the W0505 meet international electrical safety standards?
Yes—it carries CE marking per EN 61000-6-2 (EMC immunity) and EN 61000-6-4 (EMC emissions), and conforms to IEC 61000-3-2 for harmonic current limits.
Is technical documentation available in English with metrological traceability statements?
Full English-language operating manual, maintenance log templates, and factory calibration certificates (traceable to LNE, France) are supplied with each unit.
