YANRUN ZQ-300DW Intelligent Fully Automatic Metallographic Sample Cutting Machine

Overview

The YANRUN ZQ-300DW Intelligent Fully Automatic Metallographic Sample Cutting Machine is an industrial-grade, floor-standing precision cutting system engineered for reproducible, high-fidelity specimen preparation in metallurgical and materials science laboratories. It employs a three-axis (X/Y/Z) synchronized servo-driven architecture to execute complex, programmable cutting trajectories—including vertical sectioning, horizontal slicing, layered profiling, and continuous multi-pass cutting—without manual intervention. Unlike conventional single-axis cutoff machines, the ZQ-300DW integrates real-time positional feedback, closed-loop motion control, and adaptive feed-rate modulation to maintain consistent kerf width, minimal thermal distortion, and edge integrity across heterogeneous alloys, castings, sintered components, and automotive powertrain parts. Its through-type cutting chamber enables unobstructed handling of elongated specimens up to 300 mm in length and 120 mm in diameter, supporting both routine QC sampling and R&D-level microstructural analysis per ASTM E3, ISO 643, and GB/T 13298.

Key Features

• Floor-standing integrated design with rigid cast-iron base and vibration-damped structural frame for long-term geometric stability under 5.5 kW motor load
• Three-axis fully automated motion control (X: 50 mm; Y: 200 mm; Z: 200 mm) with independent infinitely variable speed regulation (1–200 mm/min) and programmable acceleration/deceleration profiles
• Eight-inch high-resolution color touchscreen HMI with intuitive icon-based workflow navigation, parameter saving, and multi-user access levels
• Through-type transparent observation chamber with LED-lit side windows, enabling real-time visual monitoring of blade engagement, coolant dispersion, and chip evacuation
• Four-channel high-flow water-cooling system with integrated 60 L reservoir, adjustable flow valves, and optional magnetic particle separator to prevent ferrous debris recirculation and extend blade life
• Precision two-layer split-stage clamping platform with micrometer-adjustable T-slots and quick-release fixtures compatible with standard metallographic vises and custom jigs
• Automated tool return-to-home sequence with mechanical end-stop verification and emergency stop interlock compliant with IEC 60204-1

Sample Compatibility & Compliance

The ZQ-300DW accommodates a broad spectrum of metallic and composite specimens—including gray iron castings, aluminum die-cast housings, titanium aerospace forgings, stainless steel weldments, and powder metallurgy compacts—without requiring secondary fixturing. Its programmable depth-of-cut (up to 350 mm effective stroke) and adjustable feed ratio support standardized specimen geometries per ASTM E3 Annex A1 (cylindrical sections), ISO 148-1 (Charpy impact preforms), and internal lab SOPs for cross-sectional analysis of coated substrates or layered battery electrodes. The machine’s control firmware logs all operational parameters—including spindle RPM, feed rate, coolant pressure, and cycle completion timestamps—with audit-trail capability suitable for GLP-compliant environments. Optional magnetic separation integration satisfies ISO 15270 requirements for metallic contaminant mitigation in precision machining workflows.

Software & Data Management

The embedded PLC-based controller supports non-volatile storage of ≥100 user-defined cutting programs, each configurable with up to 10 sequential motion segments, dwell times, spindle ramp profiles, and coolant activation triggers. All programs are exportable via USB interface in CSV format for traceability and cross-platform validation. Real-time process metrics—including cumulative cutting distance, total cycle time, and active blade runtime—are displayed on the main screen and logged locally with timestamped entries. While no remote connectivity is built-in, the system complies with RS-232/485 serial protocols for integration into centralized laboratory information management systems (LIMS) or MES platforms. Firmware updates are performed offline using signed binary files to ensure integrity and regulatory alignment with FDA 21 CFR Part 11 data security expectations.

Applications

• Precision sectioning of engine blocks, cylinder heads, and transmission casings for porosity and inclusion analysis
• Controlled-thickness slicing of additively manufactured metal parts for layer-by-layer microstructure evaluation
• Multi-depth groove cutting in turbine blades to expose subsurface fatigue zones
• High-repeatability batch cutting of tensile test coupons from rolled sheet stock
• Preparation of cross-sections from PCB-embedded metal composites for solder joint integrity assessment
• Serial sectioning of sintered ceramic-metal hybrids for grain boundary phase mapping

FAQ

What types of cutting blades are compatible with the ZQ-300DW?
Standard abrasive wheels with arbor size Ø32 mm, outer diameter 250–380 mm, and thickness 1.5–2.5 mm—certified for use with ferrous and non-ferrous metals per EN 12413.
Is the magnetic coolant separator included as standard equipment?
No—it is offered as an optional upgrade; however, the 4-channel cooling manifold and mounting interface are factory-installed to support seamless integration.
Can the machine perform unattended overnight operation?
Yes—programmed sequences include automatic shutdown upon completion, coolant level monitoring, and thermal overload protection for extended autonomous runs.
Does the ZQ-300DW meet CE or UL safety certification requirements?
The unit conforms to IEC 60204-1 (electrical safety) and ISO 13857 (safeguarding distances); CE marking requires site-specific risk assessment and local authorized representative validation.
How is calibration and maintenance documented for quality audits?
A dedicated service log menu records date-stamped entries for belt tension checks, guide rail lubrication, blade runout verification, and PLC firmware version history—all exportable for internal QA review.
