YANRUN ZQ-50DWE Intelligent Precision Automatic Cutting Machine

Overview

The YANRUN ZQ-50DWE Intelligent Precision Automatic Cutting Machine is an engineered solution for high-accuracy sectioning, slotting, and transverse cutting of heterogeneous solid specimens in materials science, metallurgy, geology, electronics, and advanced ceramics laboratories. Designed around a rigid cast-iron frame and integrated three-axis motorized positioning system (X/Y/Z), the instrument implements closed-loop PLC control to ensure repeatable motion sequencing and micron-level positional fidelity. Its core operation relies on high-speed abrasive or diamond-impregnated blade rotation—driven by a 0.75 kW brushless spindle motor operating between 2000 and 12,000 rpm—with synchronized feed-rate modulation across all axes. The machine supports vertical, horizontal, continuous, and coordinated multi-directional cuts, enabling precise preparation of cross-sections for subsequent SEM, EBSD, metallographic analysis, or thin-film deposition. Unlike manual or semi-automatic cutters, the ZQ-50DWE eliminates operator-induced variability through programmable depth-of-cut, feed ratio, and cycle repetition—critical for GLP-compliant sample prep workflows where traceability and inter-laboratory reproducibility are mandated.

Key Features

• 8-inch full-color touchscreen HMI with intuitive graphical interface for parameter entry, real-time motion visualization, and recipe storage
• Three-axis fully motorized positioning system (X: 70 mm; Y: 200 mm; Z: 70 mm) with infinitely variable speed control (0–200 mm/min per axis)
• High-torque, low-vibration spindle delivering stable rotational speeds from 2000 to 12,000 rpm under load
• Programmable cutting modes: precision transverse sectioning, serial multi-slice sectioning, depth-controlled grooving, and synchronized multi-axis profiling
• Automated recirculating water-cooling system with 40 L reservoir, temperature monitoring, and flow feedback to prevent thermal damage during prolonged cutting
• Dual-threaded adjustable clamping fixture ensuring uniform pressure distribution and minimal specimen distortion for brittle or anisotropic materials
• Real-time digital feed tracking with LCD display showing cumulative feed distance, remaining travel, and cycle progress
• Automatic homing and tool-path reset functionality ensuring mechanical repeatability after power interruption or emergency stop
• Modular blade compatibility accommodating standard 100–200 mm diameter blades with thicknesses from 0.3 to 1.0 mm (ISO 6193-1 compliant mounting)

Sample Compatibility & Compliance

The ZQ-50DWE accommodates a broad spectrum of hard and brittle materials including ferrous and non-ferrous metals, cemented carbides (e.g., WC-Co), sintered oxides (Al₂O₃, ZrO₂), optical glasses, single-crystal semiconductors (Si, GaAs), geological thin sections (basalt, granite, shale), and packaged electronic components (PCBs, BGA substrates, MEMS wafers). Its maximum hollow tube capacity (Ø30 mm) supports tubular biomaterial scaffolds and miniature heat exchanger samples. All motion control logic complies with IEC 61131-3 programming standards. The PLC architecture supports audit trail generation for critical parameters (spindle speed, feed rate, coolant status), aligning with FDA 21 CFR Part 11 requirements when paired with validated software logging. Mechanical design conforms to ISO 12100:2012 for machinery safety and EN 60204-1 for electrical equipment.

Software & Data Management

The embedded PLC firmware stores up to 99 user-defined cutting protocols, each containing spindle speed setpoints, axis feed profiles, dwell times, coolant activation thresholds, and end-of-travel logic. Protocols are recalled via touchscreen selection or external USB import/export (CSV format). While the base system does not include PC-hosted analytical software, it provides RS-232 and optional Ethernet/IP interfaces for integration into centralized lab management systems (LIMS) or MES platforms. All operational events—including start/stop timestamps, error codes, motor current draw anomalies, and coolant level warnings—are timestamped and retained in non-volatile memory for ≥30 days. Optional firmware upgrade enables CSV-based export of motion logs for post-process validation against ASTM E3-22 (Standard Guide for Preparation of Metallographic Specimens).

Applications

• Preparation of metallographic cross-sections for grain structure analysis per ASTM E3 and ISO 643
• Serial sectioning of ceramic composites for 3D microstructure reconstruction (FIB-SEM correlation)
• Depth-controlled slotting of semiconductor wafers prior to dicing or packaging inspection
• Sectioning of geological drill cores for petrographic thin-section production (ASTM D3282)
• Cutting of brittle optical components (lenses, prisms) without chipping or subsurface cracking
• Transverse sectioning of additively manufactured lattice structures for porosity quantification
• Preparation of TEM lamellae precursors via controlled trenching and lift-out staging

FAQ

What types of cutting blades are compatible with the ZQ-50DWE?
The machine accepts standard ISO 6193-1–compliant blades with outer diameters from 100 mm to 200 mm, thicknesses between 0.3 mm and 1.0 mm, and 25.4 mm arbor holes. Diamond, silicon carbide, and cubic boron nitride (CBN) bonded blades are routinely used.
Is the ZQ-50DWE suitable for cutting heat-sensitive materials?
Yes—the integrated recirculating water cooling system maintains blade and specimen interface temperatures below 40 °C during sustained operation, minimizing thermal degradation in polymers, biological composites, and low-melting-point alloys.
Can cutting parameters be exported for regulatory documentation?
Yes—via USB port, users may export protocol definitions and event logs in CSV format, supporting traceability requirements under ISO/IEC 17025 and GLP auditing frameworks.
What maintenance intervals are recommended?
Spindle bearing lubrication every 1,000 operational hours; coolant filter replacement every 3 months; linear guide rail cleaning and re-greasing every 6 months; annual calibration verification of axis encoders and feed-rate accuracy.
Does the system support remote monitoring or network integration?
Standard RS-232 enables basic SCADA integration; optional Ethernet/IP module (order code: ZQ-50DWE-ENIP) adds Modbus TCP and OPC UA support for enterprise-level connectivity.
