YANRUN ZQ-100 Intelligent Automatic Metallographic Cutting Machine

Overview

The YANRUN ZQ-100 Intelligent Automatic Metallographic Cutting Machine is an industrial-grade, floor-standing precision sample preparation system engineered for high-reproducibility metallographic sectioning in quality control laboratories, metallurgical R&D facilities, and failure analysis centers. It operates on a controlled abrasive cut-off principle—utilizing high-torque spindle rotation, programmable feed kinetics, and multi-axis positional repeatability to achieve clean, low-damage cross-sections with minimal thermal distortion or mechanical deformation. Unlike conventional manual cutters, the ZQ-100 integrates real-time adaptive feed control, enabling operators to maintain optimal cutting parameters across heterogeneous materials—including hardened steels, titanium alloys, sintered carbides, composites, and brittle ceramics—without post-cut grinding or polishing for subsequent microhardness testing (e.g., Vickers or Knoop) or direct SEM/EDS mounting.

Key Features

• PLC-based control architecture with full-color touchscreen HMI for intuitive parameter configuration, recipe storage, and process monitoring.
• Dual-layer split-stage positioning platform: enables precise angular and planar alignment of irregular, asymmetrical, or oversized specimens—critical for producing flat, parallel sections from castings, weldments, or additively manufactured parts.
• Three-forward-one-back feed algorithm with fully adjustable advance-to-retract ratio, reducing wheel wear and improving chip evacuation while minimizing heat accumulation at the cut interface.
• Variable-speed spindle drive (2840 rpm standard; 100–3000 rpm CV optional on ZQ-100A model) matched to material-specific wheel selection (e.g., resin-bonded SiC for aluminum, diamond-impregnated for ceramics).
• Triple-channel automated coolant delivery system ensures consistent, targeted lubrication across the entire cutting zone—reducing oxidation, suppressing dust, and extending wheel service life.
• Real-time digital feed tracking with LCD display: monitors cumulative feed distance, current speed, and remaining travel—supporting GLP-compliant documentation and repeatable method execution.
• Fully automatic homing and reset sequence eliminates manual repositioning errors between successive cuts or specimen batches.

Sample Compatibility & Compliance

The ZQ-100 accommodates specimens up to 380 mm (L) × 130 mm (W) × 100 mm (H), with clamping flexibility provided by its modular fixture system (standard push-type fixtures included; optional rotary, rack-and-pinion, universal, and longitudinal sectioning fixtures available). Its rigid steel frame and ABB 4.0 kW motor ensure stable torque delivery under load, meeting ISO 148-1:2016 mechanical robustness expectations for metallographic equipment. The machine’s enclosed cutting chamber complies with CE machinery directive requirements (2006/42/EC) and incorporates IP54-rated electrical components. All operational parameters—including feed rate, spindle speed, coolant flow, and cycle timing—are programmable and auditable, supporting traceability in GMP-regulated environments per FDA 21 CFR Part 11 when integrated with compliant laboratory information management systems (LIMS).

Software & Data Management

While the ZQ-100 does not feature embedded PC-based software, its PLC controller supports standardized data export via RS-232/RS-485 serial interface for integration into third-party lab automation platforms. All user-defined cutting protocols—including multi-step feed profiles, spindle ramp sequences, and coolant activation thresholds—can be saved as named methods with version timestamps. Process logs (start time, total feed distance, spindle runtime, fault codes) are retained in non-volatile memory for ≥10,000 cycles. Optional Ethernet module enables remote diagnostics and firmware updates. Audit trails comply with GLP Annex 11 principles when paired with validated external data acquisition software.

Applications

• Precision sectioning of heat-treated components for microstructure evaluation (grain size, phase distribution, inclusion analysis) per ASTM E112 and ISO 643.
• Preparation of specimens for microhardness mapping (ASTM E384) without intermediate grinding—preserving near-surface integrity for case depth or decarburization studies.
• Cutting of additive manufacturing build plates and lattice structures where geometric fidelity and minimal kerf loss are critical.
• Sectioning of coated systems (thermal barrier coatings, PVD/CVD layers) for interfacial adhesion assessment and delamination analysis.
• Routine QC sampling in foundries, forging plants, and aerospace MRO facilities requiring rapid turnaround and metrological consistency.

FAQ

What types of cutting wheels are compatible with the ZQ-100?
Standard wheel dimensions are Ø300–350 × 2.0 × Ø32 mm. The machine accepts resin-bonded, vitrified, and diamond-impregnated wheels rated for maximum peripheral speeds exceeding 80 m/s.
Is the ZQ-100 suitable for cutting non-metallic materials such as concrete or PCBs?
Yes—when equipped with appropriate wheel chemistry (e.g., diamond segments for concrete, fine-grit resin bonds for FR4 substrates) and adjusted feed/spindle parameters to avoid chipping or delamination.
Can cutting parameters be locked to prevent unauthorized modification?
Yes—PLC-level password protection supports operator-level and administrator-level access tiers, restricting changes to critical parameters like max feed speed and spindle RPM limits.
Does the system support automated batch processing of multiple specimens?
With optional Y-axis motorization and custom fixture tooling, sequential unattended cutting of up to 12 identically oriented samples is achievable using stored method files.
What maintenance intervals are recommended for the coolant system?
Coolant concentration should be verified weekly; filtration media replaced every 200 operating hours; full tank flush and inspection performed quarterly or after 500 cutting hours—whichever occurs first.
