Overview
The Drick XFX-28 Dumbbell Specimen Cutter is a precision-engineered mechanical specimen preparation system designed exclusively for the standardized fabrication of dumbbell-shaped tensile test specimens from thermoplastic, thermoset, elastomeric, and composite sheet materials. It operates on a fixed-template milling principle—where a rotating carbide-tipped cutter follows a precisely machined guide template to ensure dimensional repeatability across batches. This deterministic mechanical process eliminates operator-dependent variability inherent in manual cutting or non-guided CNC approaches, directly supporting ISO 527-2, ASTM D638 Type I–V, GB/T 1040.2, and GB/T 8804-2 compliance. The device is purpose-built for quality control laboratories, R&D centers, and rubber/plastic compounders requiring traceable, auditable specimen geometry prior to mechanical testing.
Key Features
- Robust cast-iron base and rigid column structure ensuring minimal vibration during high-speed milling (1400 rpm motor), critical for edge finish consistency and dimensional fidelity.
- Interchangeable hardened steel templates calibrated to ISO/ASTM/GB standard geometries—including Type I (1A), Type II (1B), Type IV, and Type V profiles—enabling rapid reconfiguration without recalibration.
- Quick-change collet system accommodating standardized cutting tools: standard 28 mm diameter × 45 mm length end mill; optional 60 mm and 74 mm diameter cutters for wider specimen gauges or thicker material stacks.
- Dual-safety interlock design: physical guard engagement required before motor activation; emergency stop button integrated into the front panel with NC contact monitoring.
- 380 V, 50 A three-phase power input ensures stable torque delivery under continuous load—essential for consistent chip removal when processing filled polymers or reinforced elastomers.
- Compact footprint (approx. 650 × 520 × 980 mm) and 50 kg operational weight facilitate integration into ISO 17025-accredited lab environments with limited floor space.
Sample Compatibility & Compliance
The XFX-28 accepts flat sheet specimens up to 12 mm thick and 200 mm wide, compatible with vulcanized rubber compounds (e.g., SBR, EPDM, NBR), polyolefins (PP, PE), engineering thermoplastics (PC, PA6, POM), PVC compounds, and crosslinked polyethylene (PEX). All cut specimens exhibit low burr formation and uniform edge geometry—critical for eliminating stress concentration artifacts during tensile testing per ISO 527-2 Annex A. The machine’s mechanical repeatability (±0.08 mm tolerance on gauge width, verified via CMM calibration reports) satisfies GLP documentation requirements for specimen preparation SOPs. Traceability is supported through optional engraved serial-numbered templates and tooling logs aligned with internal QA record-keeping protocols.
Software & Data Management
As a dedicated mechanical cutting system, the XFX-28 operates without embedded firmware or proprietary software—eliminating cybersecurity vulnerabilities and validation overhead associated with connected instruments. All operational parameters (tool type, template ID, batch date, operator initials) are recorded manually in laboratory notebooks or LIMS-integrated paperless workflows. This analog architecture meets FDA 21 CFR Part 11 “non-electronic record” exemptions while remaining fully compatible with ISO/IEC 17025:2017 clause 7.7 (result reporting) and ASTM E2500-13 (verification of mechanical systems). Calibration certificates for templates and cutting tools are supplied with each unit and remain valid for 24 months under normal usage conditions.
Applications
- Preparation of tensile specimens for rubber compound qualification per ASTM D3182 and ISO 2781.
- Standardized sample cutting prior to elongation-at-break, modulus, and yield point determination in polymer formulation development.
- Quality assurance in extrusion and calendering lines—enabling rapid in-process verification against GB/T 8804-2 for plastic pipes and fittings.
- Supporting ISO 10365 (rubber—determination of tear strength) when combined with notched dumbbell configurations.
- Teaching labs and certification bodies requiring ISO/IEC 17025-compliant specimen generation without digital dependencies.
FAQ
What standards does the XFX-28 comply with for specimen geometry?
It supports full conformance to ISO 527-2 (Types 1A, 1B, 2, 4, 5), ASTM D638 (Types I–V), GB/T 1040.2, and GB/T 8804-2 through certified physical templates.
Can the machine cut specimens from vulcanized rubber sheets?
Yes—designed specifically for cured elastomer sheets up to 12 mm thickness; optimal performance achieved with Shore A 40–90 compounds.
Is tool calibration required between shifts or daily?
No routine recalibration is needed; however, periodic verification (every 200 cuts or weekly) using a calibrated micrometer and reference specimen is recommended per internal QA procedures.
Does the system support automated data logging?
No—it is intentionally designed as a non-digital, mechanically governed instrument to simplify 21 CFR Part 11 compliance and reduce validation scope.
What maintenance intervals are specified for the motor and drive train?
Lubrication of the spindle bearing assembly every 500 operating hours; visual inspection of belt tension and collet integrity before each shift.
