Overview
The BROT W0504 Core Cutting Machine is an engineered solution for high-precision sectioning of cylindrical rock core samples in geological, petroleum, and materials research laboratories. Designed specifically for controlled-length coring preparation, it operates on a fixed-geometry, dual-blade parallel cutting principle—ensuring repeatable, perpendicular cross-sections with minimal kerf loss and edge deformation. Unlike general-purpose saws, the W0504 integrates mechanical presetting of cut length via adjustable inter-blade spacing, eliminating reliance on manual measurement or post-cut trimming. Its structural architecture prioritizes dimensional stability during operation: rigid base casting, precision-ground blade mounting surfaces, and vibration-damped motor coupling collectively maintain ±0.1 mm positional repeatability across repeated cuts. The system is optimized for routine use in core logging labs, reservoir characterization workflows, and ASTM D4543-compliant core sample conditioning prior to porosity, permeability, or mechanical testing.
Key Features
- Adjustable inter-blade gap mechanism enabling rapid, tool-free reconfiguration of target specimen length (e.g., 2 in, 3 in, or custom increments)
- 200 mm diameter hardened steel blades with 2 mm kerf thickness—engineered for low-residue cutting of consolidated sedimentary, igneous, and metamorphic cores
- Fully sealed ball bearings throughout the drive train, rated for continuous operation under coolant exposure and particulate-laden environments
- Corrosion-resistant wetted components: AISI 304 stainless steel frame, anodized aluminum guard panels, and chemically inert polymer splash shields
- Integrated closed-loop coolant recirculation system with sediment filtration and level monitoring—reducing consumable usage and minimizing lab wastewater generation
- Dual-mode lubrication compatibility: validated for both aqueous (deionized water) and hydrocarbon-based coolants per API RP 44 and ISO 14688-1 requirements
Sample Compatibility & Compliance
The W0504 accommodates core diameters up to 50.8 mm (2 in) and supports standard industry lengths including 50.8 mm (2 in) and 76.2 mm (3 in), with optional spacers for non-standard lengths up to 150 mm. It maintains cut-face flatness within ISO 1101 geometric tolerance class GD&T Flatness Grade 0.02 mm over full diameter—critical for subsequent CT scanning, thin-section mounting, or triaxial test specimen alignment. All structural materials comply with EU Directive 2011/65/EU (RoHS) and carry CE marking per Machinery Directive 2006/42/EC. The coolant system design aligns with ISO 14001 environmental management principles by reducing fluid consumption by >70% compared to open-flow alternatives.
Software & Data Management
While the W0504 is a manually operated mechanical system without embedded digital controls, its design incorporates traceability-ready features for GLP/GMP-aligned labs: engraved serial-numbered calibration plates on the blade carriage, standardized mounting interfaces for third-party laser displacement sensors (e.g., Keyence LK-G series), and documented maintenance intervals aligned with ISO/IEC 17025 clause 6.4.2. Optional retrofit kits support integration with laboratory information management systems (LIMS) via RS-232 or Modbus RTU for logging cut count, operational hours, and coolant replacement cycles—supporting FDA 21 CFR Part 11 audit trails when paired with compliant software platforms.
Applications
- Preparation of core plugs for routine petrophysical analysis (porosity, permeability, resistivity)
- Sectioning of drill core for thin-section petrography and SEM-EDS elemental mapping
- Generation of standardized specimens for uniaxial/triaxial compressive strength testing per ASTM D7012 and ISO 14689-1
- Sample segmentation prior to X-ray microtomography (µCT) scanning to optimize field-of-view and resolution
- Controlled-length cutting of synthetic or cementitious cores in construction materials R&D
FAQ
What core materials can be cut with the W0504?
The machine is validated for consolidated rock types including sandstone, limestone, shale, basalt, and granite. With appropriate blade selection and coolant parameters, it also processes cemented soil cores and polymer-bonded composites.
Is blade alignment recalibration required after changing cut length?
No—inter-blade parallelism is maintained via hardened linear guides and preloaded dovetail slides; alignment verification is only required annually or after impact events, per included optical alignment jig procedure.
Can the coolant system be connected to a central lab chiller?
Yes—the recirculation pump features standard 1/2″ NPT inlet/outlet ports compatible with external temperature-controlled loops operating between 10–30°C.
Does the unit meet electrical safety standards for North American laboratories?
The 220 V AC configuration complies with IEC 61000-6-2/6-4 for electromagnetic compatibility and includes dual-pole circuit protection; UL/cUL listing is available upon request with region-specific power module adaptation.
