YANRUN QG-100X Manual Metallographic Cutting Machine

Overview

The YANRUN QG-100X Manual Metallographic Cutting Machine is a precision-engineered sample preparation instrument designed for controlled sectioning of metallic and hard-brittle materials prior to metallographic analysis. Operating on a robust floor-standing architecture, it employs high-torque direct-drive spindle rotation (2840 rpm) combined with manual X-Y positioning to deliver reproducible, low-damage cuts essential for preserving microstructural integrity. Unlike automated systems, the QG-100X provides full operator control over feed rate and cutting force—critical for optimizing cut quality across heterogeneous or heat-sensitive specimens such as welded joints, coated alloys, or aged turbine blades. Its design prioritizes mechanical stability, thermal management, and ergonomic accessibility, making it suitable for routine use in metallurgical laboratories operating under ISO/IEC 17025-compliant workflows.

Key Features

• High-power 4.0 kW motor ensures consistent spindle torque during prolonged cutting of hardened steels, cast irons, and nickel-based superalloys.
• Dual-axis manual positioning system: 50 mm fine-adjustment X-travel and 250 mm Y-axis stroke enable precise specimen alignment relative to the abrasive wheel plane.
• Split-type dual-layer movable clamping platform accommodates irregular geometries and permits multi-angle mounting—essential for directional microstructure evaluation per ASTM E3 and ISO 643.
• Integrated 4-channel water-cooling system delivers targeted coolant flow to both blade interface and specimen surface, minimizing thermal distortion and extending abrasive wheel life.
• 80 L capacity reservoir supports extended operation without frequent refilling; closed-loop filtration compatibility allows integration with centralized lab coolant management systems.
• Sturdy cast-iron base and reinforced column structure suppress vibration transmission, ensuring dimensional repeatability within ±0.1 mm across successive cuts.
• Compliance-ready mechanical design facilitates documentation of operational parameters (e.g., spindle speed, feed distance, coolant flow verification) required for GLP/GMP traceability.

Sample Compatibility & Compliance

The QG-100X accepts specimens up to 380 mm (L) × 130 mm (W) × 100 mm (H), supporting standard metallographic blanks, rolled plates, extrusions, and machined components. It is routinely used for sectioning ferrous and non-ferrous alloys—including stainless steels, aluminum 7xxx series, titanium Grade 5, and copper-nickel marine alloys—as well as sintered ceramics, carbide tooling inserts, and composite laminates. The machine meets mechanical safety requirements per EN 692 (machine tools – safety) and incorporates splash guards, emergency stop circuitry, and interlocked access doors aligned with CE directives. While not an electronic data-acquisition system, its mechanical repeatability and parameter transparency support audit readiness for ISO 17025 accreditation and internal QA/QC protocols referencing ASTM E3, ISO 14487, and GB/T 226-2015.

Software & Data Management

As a manually operated mechanical system, the QG-100X does not incorporate embedded firmware or digital control interfaces. All operational parameters—including spindle activation, coolant valve actuation, and manual feed positioning—are executed via tactile controls with physical feedback. This analog architecture eliminates software validation burdens associated with FDA 21 CFR Part 11 compliance, rendering it inherently suitable for regulated environments where deterministic, non-programmable behavior is preferred. Laboratories may document usage via standardized logbooks or integrate the unit into LIMS workflows using external barcode-scanned job tickets that record specimen ID, blade type, cut orientation, and operator signature—fully compatible with GLP audit trails.

Applications

• Preparation of cross-sections from structural welds for fusion zone morphology assessment per AWS D1.1.
• Cutting of bearing raceways and gear teeth to evaluate case depth, decarburization, and subsurface cracking.
• Sectioning of aerospace engine components (e.g., turbine disks, vanes) for grain size analysis per ASTM E112.
• Routine QC sampling in automotive foundries for verifying casting porosity distribution and inclusion content.
• Specimen isolation in failure analysis labs investigating fatigue origins, stress corrosion cracking, or hydrogen embrittlement.
• Academic instruction in materials science curricula for hands-on demonstration of sectioning artifacts (e.g., smearing, pull-out, overheating) and mitigation techniques.
• Preparation of electrolytic etching substrates for subsequent SEM-EBSD orientation mapping.

FAQ

Is the QG-100X compliant with international safety standards?

Yes—the machine conforms to EN 692 for mechanical press safety principles and includes CE-marked electrical components, emergency stop functionality, and hydraulic/pneumatic safety interlocks where applicable.
Can it accommodate diamond-impregnated blades for ceramic or cemented carbide cutting?

Yes—its blade arbor accepts standard ISO 4752-compliant flanges for 300–350 mm diameter wheels, including resin-bonded diamond, vitrified alumina, and silicon carbide variants.
What maintenance intervals are recommended for long-term reliability?

Monthly inspection of coolant pump seals and hose integrity; biannual lubrication of X-Y lead screws and spindle bearings; annual calibration of mechanical stops and travel limiters per manufacturer service bulletin QG-100X-SV-2023.
Does YANRUN provide application support for method development?

Yes—technical documentation includes ASTM-aligned cutting parameter guidelines (feed rate vs. hardness), and regional application engineers offer remote consultation for specimen-specific protocol optimization.
Is retrofitting with digital position encoders or PLC control possible?

No—the QG-100X is engineered as a fixed-function mechanical system; modifications void warranty and compromise certified safety architecture. For automated workflows, consider YANRUN’s QG-200A series with integrated motion control.
