Overview
The Struers Accutom-100 is a high-precision, fully integrated metallographic cutting system engineered for reproducible specimen preparation in quality control, failure analysis, and R&D laboratories. Built upon Struers’ decades of expertise in materials sample preparation, the Accutom-100 employs a dual-mode architecture—combining precision sawing with controlled grinding—to deliver flat, damage-free cross-sections across a broad spectrum of metallic, ceramic, composite, and sintered materials. Its core mechanical design follows the Couette-type motion principle for grinding mode, where bidirectional X-axis scanning (multi-pass oscillation) ensures uniform material removal and eliminates edge rounding or topographical distortion. The system operates under closed-loop motorized positioning, enabling deterministic control over cut depth, feed rate, and wheel engagement—critical parameters for maintaining microstructural integrity prior to polishing and microscopic evaluation.
Key Features
- Motorized XYZ-stage with 5 µm incremental resolution in X-direction (specimen translation) and 100 µm resolution in Y-direction (wheel vertical approach), ensuring repeatable positioning for serial sectioning or multi-location cuts.
- Dual-mode operation: Switch seamlessly between abrasive sawing (using diamond-impregnated or SiC wheels) and precision grinding (with cup or segmental bonded wheels) via intuitive interface selection.
- Intelligent rotary-push control panel with context-sensitive icons and parameter grouping—eliminates menu nesting and reduces operator training time by up to 40% compared to legacy systems.
- Integrated coolant management system with adjustable flow rate and directional nozzles to maintain thermal stability during cutting, minimizing phase transformation or recast layer formation in heat-sensitive alloys.
- Rigid cast-iron frame with vibration-damped base and linear guideways certified to ISO 230-2 positional accuracy standards, ensuring long-term mechanical stability under continuous lab use.
Sample Compatibility & Compliance
The Accutom-100 accommodates specimens up to 100 mm in diameter and 60 mm in height, supporting standard metallographic mounts (epoxy, phenolic, acrylic) as well as unmounted bulk samples. It is validated for use with ASTM E3, ISO 14487, and EN 10365-compliant cutting protocols. All electrical and EMC performance conforms to CE marking requirements under Directive 2014/30/EU (EMC) and 2006/42/EC (Machinery). Safety interlocks, emergency stop circuitry, and dust extraction port integration comply with OSHA 1910.212 and EN 60204-1. The system supports GLP/GMP documentation workflows when paired with Struers LabReport software (optional add-on).
Software & Data Management
While the Accutom-100 operates as a standalone instrument with embedded firmware, it interfaces seamlessly with Struers’ LabReport v4.x suite for audit-trail-enabled method storage, user access logging, and PDF report generation. Each cut cycle logs timestamp, operator ID, wheel type, coolant pressure, feed speed, and total cutting time—structured data exportable via USB or Ethernet for LIMS integration. Firmware updates are delivered via secure HTTPS portal, and all configuration changes support rollback to previous versions. The system meets FDA 21 CFR Part 11 requirements for electronic records when deployed with LabReport’s role-based authentication and digital signature modules.
Applications
- Precision sectioning of turbine blades, weld joints, and additive-manufactured components for porosity and grain structure analysis.
- Controlled thickness reduction of brittle ceramics and optical glasses prior to TEM lamella preparation.
- Serial sectioning of PCB assemblies and electronic packaging for solder joint integrity assessment.
- Preparation of coated substrates (e.g., thermal barrier coatings, PVD layers) with minimal delamination risk through low-stress grinding mode.
- High-throughput sample division in automotive QA labs performing tensile bar extraction per ISO 6892-1.
FAQ
What types of cutting wheels are compatible with the Accutom-100?
Standard 200 mm diameter wheels with ISO 40 taper arbor fitment—including resin-bonded diamond, metal-bonded diamond, and silicon carbide abrasive wheels—are supported. Wheel geometry must conform to EN 12413 for safety certification.
Can the Accutom-100 be integrated into an automated sample prep line?
Yes—the system features RS-232 and Modbus TCP communication ports for external PLC coordination. Optional robotic arm interface kits (Struers RoboLink) enable synchronized loading/unloading with third-party automation platforms.
Is grinding mode suitable for non-metallic materials such as concrete or polymers?
Grinding mode is optimized for hard, brittle, or heterogeneous materials. For soft polymers or elastomers, sawing mode with low-speed, high-coolant protocols is recommended; grinding may induce thermal deformation or smearing.
Does the system include calibration documentation traceable to national standards?
Each unit ships with a factory calibration certificate covering positional accuracy, motor torque consistency, and coolant flow linearity—traceable to DKD/DAkkS-accredited metrology labs in Denmark.
