Overview
The TianYuan TY-5002 Dumbbell Specimen Cutting Machine is a precision-engineered sample preparation system designed specifically for the rubber and plastic industries. It employs a high-speed rotating end mill to accurately machine standardized dumbbell- and rectangular-shaped tensile specimens from semi-rigid and rigid non-metallic polymer sheets or molded plaques. The machine operates on a fixed-tool, moving-workpiece principle: the specimen blank is clamped securely in a precision-machined fixture, then advanced manually or guided along a calibrated linear path against a stationary, high-RPM cutting tool. This configuration ensures dimensional repeatability and edge integrity critical for mechanical testing compliance. The integrated dust extraction interface connects directly to an external industrial vacuum system, minimizing airborne particulate generation and maintaining operator safety and workspace cleanliness—key considerations under OSHA 1910.94 and ISO 8502-3 surface cleanliness guidelines.
Key Features
- Robust cast-iron base and rigid column structure provide vibration damping and long-term geometric stability during repetitive machining cycles.
- Dual-standard fixture set included: fully compliant with GB/T 1040.2–2022 (Types I and II dumbbell geometries), with traceable dimensional certification per ISO/IEC 17025-accredited calibration protocols.
- Adjustable manual feed mechanism with vernier scale (0.02 mm resolution) enables precise control over cut depth and lateral positioning—essential for achieving consistent thickness and parallelism across specimens.
- 2800 rpm spindle speed optimized for common thermoplastics (e.g., PP, PE, ABS, PC) and thermosets (e.g., phenolic, epoxy laminates), balancing material removal rate with surface finish quality (typical Ra < 3.2 µm).
- Modular fixture interface supports rapid reconfiguration for custom geometries—including ASTM D638 Types I–V, ISO 527-2 Type 1A, and user-defined profiles—without requiring structural modification to the mainframe.
Sample Compatibility & Compliance
The TY-5002 accommodates sheet specimens up to 12 mm thick and 150 mm wide, suitable for unfilled and moderately filled polymers (e.g., ≤30 wt% glass fiber or mineral filler). It is routinely deployed in laboratories conducting QC/QA per ISO 179 (impact), ISO 527 (tensile), and ASTM D790 (flexural) test standards. All supplied fixtures are dimensionally verified against national metrological references and documented in a traceable certificate of conformity. The machine’s mechanical design adheres to CE machinery directive 2006/42/EC essential health and safety requirements, including emergency stop functionality, guarded cutting zone, and electrical insulation per IEC 60204-1.
Software & Data Management
As a purely electromechanical benchtop system, the TY-5002 does not incorporate embedded firmware or digital controls. However, its operational consistency supports full integration into GLP- and GMP-regulated environments through documented procedural controls. Laboratories may record specimen lot numbers, operator IDs, fixture serials, and cut dates in structured logbooks or LIMS-compatible spreadsheets. For audit readiness, all calibration records, maintenance logs, and fixture verification reports can be archived in accordance with FDA 21 CFR Part 11 principles when managed via validated electronic systems.
Applications
- Preparation of tensile test specimens for polyolefins, engineering plastics, elastomers, and composite laminates prior to mechanical property evaluation.
- Generation of standardized geometry blanks for subsequent environmental stress cracking (ESC) testing per ASTM D5397.
- Routine QC sampling in extrusion and injection molding facilities to verify batch-to-batch consistency in raw material processing behavior.
- Research-grade specimen fabrication in polymer physics labs studying strain-rate dependence, creep response, or fracture initiation thresholds.
- Supporting accredited testing laboratories seeking CNAS (ISO/IEC 17025) or A2LA recognition for mechanical testing scope expansion.
FAQ
Is the TY-5002 compatible with ASTM D638 Type IV specimens?
Yes—custom fixtures for ASTM D638 Type IV (12.7 mm width, reduced section) are available upon request and supplied with dimensional validation report.
Can the machine process carbon-fiber-reinforced thermoplastics (CFRTP)?
It is capable of machining CFRTPs up to 20% fiber loading using carbide-tipped end mills; however, tool wear rate increases significantly—recommended replacement interval is tracked per 50 specimens.
Does the unit include a vacuum pump?
No—the TY-5002 features a standardized 50 mm vacuum port (ISO-KF25 compatible) but requires connection to an externally sourced industrial vacuum system (minimum 120 m³/h flow, ≥−5 kPa static pressure).
What maintenance schedule is recommended?
Lubrication of linear guides every 200 operating hours; spindle bearing inspection annually or after 2,000 cutting cycles; fixture alignment verification before each production shift using certified gauge blocks.
Is technical support available outside China?
Yes—TianYuan provides remote troubleshooting, fixture CAD files, and application engineering consultation via English-speaking support engineers based in Singapore and Germany.
