WEIYEE Q-100BL Automatic Metallographic Cutting Machine

Overview

The WEIYEE Q-100BL Automatic Metallographic Cutting Machine is an industrial-grade, floor-standing specimen preparation system engineered for precision sectioning of metallic, ceramic, and composite materials in metallurgical, failure analysis, and quality control laboratories. It operates on the principle of controlled abrasive cutting under continuous coolant flow—utilizing high-torque motor-driven rotation of reinforced resin-bonded silicon carbide or diamond-impregnated wheels to achieve clean, low-distortion cross-sections. The machine’s enclosed cutting chamber ensures operator safety and compliance with occupational hygiene standards (e.g., OSHA 1910.212 and EN 60204-1), while its rigid cast-iron base and vibration-dampened structural design minimize runout and improve cut repeatability across sequential specimens.

Key Features

• Floor-standing robust architecture: Designed for permanent installation in QC labs and metallography suites; accommodates heavy-duty fixtures and large workpieces without compromising stability.
• Dual-mode operation: Switch seamlessly between manual feed for fine positioning and programmable automatic feed for reproducible, unattended cuts—ideal for batch processing of standardized samples per ASTM E3-22 or ISO 643.
• Closed-loop cooling system: Integrated 60 L water reservoir with temperature monitoring, filtration, and recirculation pump maintains consistent coolant delivery at optimal flow rate and thermal stability—reducing heat-affected zones and preventing microstructural alteration during sectioning.
• Precision X-axis traverse: 50 mm linear travel with micrometer-scale positioning accuracy enables precise depth-of-cut control, critical for serial sectioning and layered material analysis.
• Intuitive color touchscreen interface: Graphical HMI supports multi-language UI (English default), real-time parameter display (feed rate, spindle speed, elapsed time), and user-defined cutting protocols with password-protected access levels for GLP/GMP environments.
• Safety-integrated drive system: 3 kW three-phase motor with electromagnetic brake ensures immediate spindle stop (<0.5 s) upon emergency stop activation or lid interlock disengagement—meeting Category 3 PLd requirements per ISO 13849-1.

Sample Compatibility & Compliance

The Q-100BL accommodates a wide range of conductive and non-conductive specimens—including ferrous and non-ferrous alloys, sintered powders, coated substrates, and brittle ceramics—up to Φ100 mm in diameter and 120 mm in height. Its adjustable clamping vise (with T-slot base and modular fixture options) supports flat, cylindrical, and irregular geometries. All wet-cutting operations conform to ISO 14855-1 for controlled environmental exposure and ASTM E3-22 Annex A1 for metallographic sample preparation documentation. The system supports traceability through embedded audit trails (user ID, timestamp, protocol ID) compatible with FDA 21 CFR Part 11–compliant data management workflows when integrated with laboratory information systems (LIMS).

Software & Data Management

While the Q-100BL operates via embedded firmware rather than PC-dependent software, its touchscreen controller logs all operational events—including start/stop times, selected protocols, motor current draw, and coolant temperature—in a non-volatile internal memory buffer (retains ≥10,000 entries). Export is supported via USB 2.0 port (CSV format) for integration into external QA databases or statistical process control (SPC) platforms. Optional RS-485 Modbus RTU interface enables remote monitoring and centralized fleet management in multi-instrument facilities adhering to ISA-88/ISA-95 frameworks.

Applications

• Preparation of specimens for optical microscopy (OM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD)
• Sectioning of weld joints, heat-affected zones (HAZ), and coating interfaces for adhesion and porosity assessment
• Routine QC sampling in foundries, aerospace component manufacturing, and power generation equipment maintenance
• Failure analysis of fractured components requiring undisturbed fracture surface preservation
• Serial sectioning for 3D microstructure reconstruction and quantitative metallography (e.g., grain size, phase fraction per ASTM E112/E562)

FAQ

What types of cutting wheels are compatible with the Q-100BL?
Standard mounting accepts Φ350 × 32 × 2.5 mm wheels with ISO 4017-1 flange geometry. Common configurations include 125–220 grit SiC for aluminum/brass, 80–125 grit diamond for hardened steels and ceramics, and resin-bonded variants compliant with EN 12413 for safe high-speed operation.

Is the machine suitable for use in ISO/IEC 17025-accredited laboratories?
Yes—the Q-100BL supports documented calibration of feed rate and spindle speed, retains full operational logs, and permits protocol validation per ISO/IEC 17025 Clause 7.7; users must establish and verify performance criteria (e.g., surface roughness Ra ≤ 1.6 µm, kerf width variation ≤ ±0.05 mm) during method validation.

Does it support automated cycle sequencing for unattended overnight operation?
The Q-100BL supports up to 10 stored cutting programs with independent feed rate, dwell time, and spindle speed profiles—but requires operator-initiated start and post-cycle inspection; fully autonomous multi-step sequences (e.g., cut → rinse → dry) necessitate external robotic integration.
