YANRUN ZQ-50DW Intelligent Precision Automatic Cutting Machine

Overview

The YANRUN ZQ-50DW Intelligent Precision Automatic Cutting Machine is an industrial-grade, programmable sample preparation system engineered for high-accuracy sectioning, slotting, and transverse cutting of heterogeneous solid materials in laboratory and R&D environments. Based on a rigid three-axis (X/Y/Z) servo-driven architecture and governed by a deterministic PLC control logic, the ZQ-50DW implements precise kinematic coordination between blade feed motion and spindle rotation—enabling reproducible material removal with micron-level depth resolution. Its core operation relies on controlled abrasive or diamond-blade mechanical cutting under continuous coolant flow, conforming to standardized specimen preparation workflows required in metallurgy, geoscience, semiconductor packaging, ceramic engineering, and electronic component failure analysis. Unlike manual or semi-automatic cutters, the ZQ-50DW supports unattended multi-pass sequencing with real-time positional feedback, making it suitable for batch processing of specimens where dimensional consistency and edge integrity are critical to downstream analysis (e.g., SEM cross-sectioning, metallographic mounting, or wafer dicing validation).

Key Features

• 8-inch full-color TFT touchscreen HMI with intuitive graphical interface for parameter entry, program storage, and real-time motion monitoring
• PLC-based closed-loop motion control ensuring synchronized X/Y/Z axis positioning with repeatable accuracy ≤ ±5 µm per axis
• Infinitely variable spindle speed range (2000–12000 rpm) optimized for diverse blade types and material hardness profiles—from soft aluminum alloys to sintered tungsten carbide and fused silica
• Three independent linear axes with programmable feed rates (0–200 mm/min), enabling complex cutting strategies: vertical sectioning, horizontal slicing, depth-controlled grooving, and coordinated multi-angle cuts
• Automated recirculating water-cooling system (40 L reservoir) with temperature-stable flow delivery to suppress thermal distortion and extend blade service life
• Dual-thread mechanical clamping fixture designed for secure, vibration-damped fixation of cylindrical, rectangular, or irregularly shaped specimens up to Ø30 mm
• Real-time digital display of cumulative feed displacement, cycle count, and operational status—fully traceable for GLP-compliant documentation
• Auto-reset functionality after cycle completion, reducing operator intervention and supporting sequential unattended operation

Sample Compatibility & Compliance

The ZQ-50DW accommodates a broad spectrum of rigid, non-ductile, and quasi-brittle materials commonly encountered in materials science laboratories. Validated use cases include ferrous and non-ferrous metals (e.g., stainless steel, Ti-6Al-4V), cemented carbides, technical ceramics (Al₂O₃, SiC), optical glasses, geological thin sections (granite, basalt), single-crystal substrates (Si, GaAs), and encapsulated microelectronic packages. All cutting protocols align with ASTM E3-22 (Standard Guide for Preparation of Metallographic Specimens) and ISO 14577-1:2022 (Metallic materials — Instrumented indentation test). The machine’s programmable depth control and feed repeatability support compliance with internal QA/QC procedures requiring documented cutting parameters per specimen lot—essential for ISO/IEC 17025-accredited testing laboratories.

Software & Data Management

While the ZQ-50DW operates via embedded PLC firmware without external PC dependency, its HMI stores up to 99 user-defined cutting programs—including spindle RPM, X/Y/Z travel limits, feed velocity profiles, coolant activation timing, and pause points. Each program retains timestamped execution logs (start time, total cycles, emergency stops) accessible via USB export for audit trail generation. The system supports optional integration with Lab Information Management Systems (LIMS) through RS-232 or Modbus RTU serial protocols, enabling automated job dispatch and result metadata capture. All stored parameters adhere to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) when used in regulated environments governed by FDA 21 CFR Part 11 or EU Annex 11 requirements.

Applications

• Preparation of cross-sectional samples for scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS)
• Sectioning of heat-treated alloy coupons for microstructure evaluation per ASTM E112
• Controlled-depth grooving of PCB substrates prior to delamination analysis
• Serial sectioning of rock cores for petrographic imaging and porosity mapping
• Cutting of brittle semiconductor wafers and LED packages without chipping or subsurface cracking
• Manufacturing of standardized tensile test specimens from additively manufactured metal parts

FAQ

What types of cutting blades are compatible with the ZQ-50DW?
The machine accepts standard diamond-impregnated or resin-bonded abrasive blades with inner diameter 25.4 mm, outer diameter 100–200 mm, and thickness 0.3–1.0 mm. Blade selection must match material hardness and desired surface finish per manufacturer guidelines.

Is the ZQ-50DW suitable for cutting soft or ductile materials like pure copper or polymers?
It is not recommended for highly ductile or low-melting-point materials without specialized blade geometry and reduced feed rates; excessive plastic deformation may compromise dimensional fidelity. Consult application engineering for feasibility assessment.

Does the system provide data export capabilities for quality records?
Yes—cutting program parameters and cycle logs can be exported via USB flash drive in CSV format, supporting traceability in ISO 17025 or GMP-regulated workflows.

What maintenance intervals are recommended for long-term reliability?
Daily coolant level and filtration check; monthly inspection of guide rails and belt tension; annual calibration of position encoders and spindle speed feedback loop—per the included maintenance schedule in the technical manual.
