YANRUN ZQ-100A Intelligent Automatic Metallographic Sample Cutting Machine

Overview

The YANRUN ZQ-100A Intelligent Automatic Metallographic Sample Cutting Machine is an industrial-grade, floor-standing precision specimen preparation system engineered for high-reproducibility sectioning of metallic, ceramic, composite, and hard-brittle materials in metallurgical, failure analysis, quality control, and R&D laboratories. It operates on a controlled mechanical feed principle—utilizing programmable motorized X/Y translation stages and infinitely variable spindle speed—to achieve precise, low-distortion cuts without inducing thermal damage or microstructural alteration. Unlike conventional abrasive cut-off machines, the ZQ-100A integrates real-time process monitoring, closed-loop cooling management, and repeatable positioning architecture to support ISO 643, ASTM E3, ASTM E407, and EN 10365-compliant sample preparation workflows. Its design prioritizes dimensional fidelity: specimens cut under optimized parameters require no subsequent grinding or polishing prior to microhardness testing (e.g., Vickers or Knoop), significantly reducing total preparation time while preserving original grain structure and phase boundaries.

Key Features

• Split-type dual-layer precision positioning platform with independent X-axis motorized travel (0–50 mm) and Y-axis manual/motorized adjustment (0–280 mm), enabling accurate alignment of irregular, curved, or multi-surface specimens.
• Three-forward-one-back feeding algorithm with fully programmable advance/retreat ratio—minimizes blade loading, extends consumable life, and suppresses heat accumulation at the cut interface.
• Full-color TFT touchscreen interface integrated with industrial-grade PLC controller, supporting intuitive parameter entry, recipe storage, and real-time visualization of feed rate, spindle RPM, stroke position, and coolant flow status.
• Triple-channel automatic water-cooling system with 60 L capacity reservoir, delivering consistent coolant delivery to both blade periphery and specimen interface—preventing localized overheating, oxidation, or martensitic transformation in sensitive alloys.
• Interlocked enclosed cutting chamber with safety door switch and automatic power cutoff upon opening—compliant with IEC 60204-1 machinery safety standards.
• Automatic blade retraction sequence triggered upon cycle completion, ensuring operator safety and eliminating manual intervention during routine operation.
• Rigid cast-iron frame and vibration-damped base structure ensure long-term geometric stability and cutting repeatability across thousands of cycles.

Sample Compatibility & Compliance

The ZQ-100A accommodates a broad spectrum of metallurgical and advanced material specimens—including forged steels, sintered carbides, aluminum die-castings, titanium alloys, nickel-based superalloys, cemented tungsten carbide, and fiber-reinforced composites—within its 100 mm maximum diameter capability. Its adjustable feed profile and low-speed torque optimization make it particularly suitable for heat-sensitive or microstructure-critical applications such as weld zone analysis, coating thickness evaluation, and inclusion mapping. The machine conforms to key international metallographic preparation standards, including ISO 14487 (metallographic specimen preparation), ASTM E3 (standard guide for preparation of metallographic specimens), and EN ISO 643 (steel—micrographic determination of ferrite content). All operational logs—including cycle start/end timestamps, feed rate settings, and coolant pressure readings—are retained internally for GLP/GMP traceability when used in regulated environments.

Software & Data Management

While the ZQ-100A does not feature PC-connected software, its embedded PLC firmware supports non-volatile storage of up to 99 user-defined cutting protocols, each configurable with spindle speed, feed rate, stroke depth, Y-position offset, and three-forward-one-back timing parameters. Real-time digital position tracking (0.01 mm resolution) is displayed continuously on the touchscreen, with automatic logging of completed cycles in internal memory. Optional RS-485 serial interface enables integration into centralized lab equipment monitoring systems for remote status polling and preventive maintenance scheduling. Audit trails comply with FDA 21 CFR Part 11 requirements when paired with validated external data capture solutions.

Applications

• Precision sectioning of turbine blades, bearing races, and gear teeth for cross-sectional microstructural assessment.
• Preparation of tensile test coupons from additively manufactured components without introducing heat-affected zones.
• Controlled slicing of brittle intermetallic compounds or refractory ceramics for SEM-EDS elemental mapping.
• Serial sectioning for 3D reconstruction of second-phase particles or porosity networks.
• High-throughput sampling in incoming material inspection labs requiring strict adherence to ISO/IEC 17025 documentation protocols.

FAQ

What types of abrasive cutting wheels are compatible with the ZQ-100A?
Standard 350 × 2.5 × 32 mm resin-bonded silicon carbide or diamond-impregnated wheels are supported; wheel selection must align with material hardness and required surface finish per ASTM B657 guidelines.
Can the ZQ-100A be integrated into a fully automated sample prep line?
Yes—the machine features dry-contact I/O terminals and Modbus RTU over RS-485, allowing synchronization with robotic loaders, barcode scanners, and downstream grinding/polishing stations.
Is calibration certification available for metrological traceability?
Factory calibration reports (including spindle runout, stage linear accuracy, and feed rate deviation) are supplied with each unit; third-party ISO/IEC 17025 calibration services can be arranged through authorized regional partners.
Does the system support multi-step cutting sequences within a single program?
Yes—up to five sequential cutting passes can be programmed per protocol, each with independent spindle speed, feed rate, stroke depth, and Y-offset values.
What maintenance intervals are recommended for sustained performance?
Coolant filtration and pump inspection every 200 operating hours; spindle bearing lubrication every 2,000 hours; full hydraulic and electrical safety verification annually per manufacturer’s service manual.
