YANRUN SYJ-160 Low-Speed Diamond Precision Cutting Machine

Overview

The YANRUN SYJ-160 Low-Speed Diamond Precision Cutting Machine is a laboratory-grade metallographic sample preparation instrument engineered for high-accuracy, low-damage sectioning of brittle, hard, or heterogeneous materials. Operating on the principle of controlled abrasive cutting using diamond-impregnated or bonded abrasive blades rotating at precisely regulated speeds (20–600 rpm), the SYJ-160 minimizes thermal distortion, microcracking, and edge chipping—critical requirements for subsequent microscopy, XRD, SEM, or mechanical testing. Its low-speed architecture ensures stable material removal rates suitable for single-crystal substrates, optical ceramics, geological specimens, refractory composites, PCB laminates, and metallurgical samples where structural integrity of the cut surface must be preserved. Designed for unattended operation with automatic spindle stop upon cycle completion, the system supports reproducible, GLP-aligned sample preparation workflows in academic research labs, industrial R&D centers, and quality control facilities.

Key Features

• Infinitely variable speed control (20–600 rpm) enables optimal blade–material interaction across diverse hardness and toughness profiles—from soft polymers to sapphire wafers.
• Mechanical + digital dual-readout micrometer feed system delivers 0.01 mm positioning resolution, ensuring repeatable slice thickness and precise depth-of-cut registration.
• Two-axis adjustable sample stage: horizontal 360° rotation and vertical tilt (±15°) accommodate angled cuts, cross-sectional profiling, and anisotropic material orientation.
• 50 mm total travel with 25 mm fine-adjustment range allows both coarse positioning and micron-level final approach—ideal for serial sectioning or stepwise depth profiling.
• Robust cast-aluminum frame and vibration-damped base provide mechanical stability during extended cutting cycles, reducing runout and improving blade life.
• Digital spindle rotation counter facilitates process documentation and correlation between rotational count and material removal volume—supporting traceability in regulated environments.
• Integrated safety interlock and auto-shutdown function enable compliant unattended operation per ISO 13857 and IEC 61000-6-2 guidelines.

Sample Compatibility & Compliance

The SYJ-160 accommodates a broad spectrum of rigid and semi-rigid materials including single crystals (SiC, GaN, quartz), technical ceramics (Al₂O₃, ZrO₂), optical glasses, geological thin sections (basalt, granite, shale), refractory bricks, metallic alloys (Ti-6Al-4V, Inconel), PCBs, carbon composites, and polymer-matrix composites. Its 150 mm blade capacity (Φ150 × 12.7 mm arbor) supports larger cross-sections than standard 100 mm systems, while the modular夹具 system—including 2D adjustable vise, axial counterweights, and sample mounting plates—ensures secure clamping without deformation. The instrument complies with general electrical safety standards (IEC 61010-1) and is compatible with laboratory quality management frameworks requiring audit-ready documentation (e.g., ISO/IEC 17025, ASTM E3, ISO 14729 for ophthalmic device prep). Optional blade configurations support method validation per ASTM C1327 (diamond abrasives) and ISO 6474 (ceramic fracture toughness specimen preparation).

Software & Data Management

While the SYJ-160 operates as a standalone electromechanical system without embedded software, its digital micrometer and spindle rotation counter generate discrete, manually recordable data points compatible with external LIMS or ELN integration. Users may log cutting parameters—including speed setpoint, feed displacement, rotation count, blade type, coolant usage, and sample ID—into standardized templates aligned with FDA 21 CFR Part 11 Annex 11 expectations for electronic records. All standard and optional blades are supplied with batch-certified dimensional and bonding specifications, enabling full traceability from raw material to finished specimen. Documentation packages include calibration certificates for the digital readout (traceable to NIM, China), mechanical assembly drawings, and maintenance logs for GMP-aligned facility audits.

Applications

• Precision slicing of semiconductor wafers and optoelectronic crystals for TEM lamella preparation and epitaxial layer analysis.
• Sectioning of geological core samples for petrographic thin-sectioning and micro-CT scanning alignment.
• Controlled cross-sectioning of additively manufactured metal parts to assess porosity distribution and melt pool boundaries.
• Preparation of ceramic armor tile interfaces for interfacial adhesion and residual stress evaluation via Raman mapping.
• Cutting of fiber-reinforced polymer laminates at defined angles to study delamination onset under shear loading.
• Routine metallographic sectioning of heat-treated alloys for grain size quantification (ASTM E112) and inclusion rating (ASTM E45).

FAQ

What types of diamond blades are compatible with the SYJ-160?

The SYJ-160 accepts all 150 mm diameter blades with a 12.7 mm center arbor, including edge-bonded, electroplated, and full-sintered diamond variants, as well as SiC and alumina abrasive blades.
Is coolant delivery integrated into the system?

No built-in pump or reservoir is included; however, the machine features threaded ports and mounting brackets for external drip-feed or flood-cooling systems compliant with ISO 6506-1 cooling requirements.
Can the SYJ-160 perform sequential multi-layer sectioning?

Yes—its 0.01 mm feed resolution, 25 mm fine-travel range, and digital position memory (via manual logging) support reproducible serial sectioning protocols for 3D reconstruction studies.
Does the instrument meet CE or UL certification requirements?

The SYJ-160 conforms to IEC 61010-1 for laboratory electrical equipment; CE marking is available upon request with EU Representative documentation and RoHS compliance verification.
What maintenance intervals are recommended for long-term reliability?

Belt tension and bearing lubrication should be verified every 500 operating hours; digital encoder calibration is recommended annually or after impact events, per manufacturer’s service bulletin SB-SYJ160-REV3.
