Ray-Ran CNC2 Precision Sample Contour Cutting Machine

Overview

The Ray-Ran CNC2 Precision Sample Contour Cutting Machine is a fully enclosed, computer numerical control (CNC) system engineered for high-accuracy contour cutting of polymeric, composite, metallic, and elastomeric test specimens in compliance with international standard test methods. Designed and manufactured in the United Kingdom, the CNC2 employs a rigid cast-iron frame and a high-torque, variable-speed 1.5 kW spindle to deliver consistent material removal across diverse sample geometries—including tensile bars (ISO 527, ASTM D638), impact test specimens (ISO 179, ASTM D256), flexural bars (ISO 178, ASTM D790), and custom-shaped coupons for fatigue or creep analysis. Its closed-loop motion control architecture—based on precision linear rails and preloaded ball screws—ensures sub-millimetre repeatability over extended operational cycles. The machine operates exclusively via external PC-based FlashCut CNC software, supporting G-code programming and enabling direct integration with CAD-generated toolpaths for traceable, auditable specimen fabrication workflows.

Key Features

• Fully interlocked safety enclosure with optically shielded viewing window, internal LED lighting, and dual-channel emergency stop circuitry compliant with EN ISO 13857 and EN 60204-1.
• High-resolution XYZ-axis positioning system with travel ranges of 600 mm (X), 300 mm (Y), and 175 mm (Z), enabling full processing of specimens up to 910 × 480 mm on the reinforced aluminium worktable.
• Variable-speed air-cooled spindle delivering 2,400–24,000 rpm, optimized for carbide end mills, diamond-coated cutters, and abrasive wheels used in thermoset, thermoplastic, and fibre-reinforced composites.
• Robust mechanical architecture featuring vibration-damped base, hardened steel guide surfaces, and backlash-compensated ball screw drives to maintain dimensional fidelity across multi-hour cutting sequences.
• FlashCut CNC software platform supports ISO 6983 (G-code) programming, tool offset management, feed rate profiling, and real-time axis position monitoring—compatible with Windows OS and exportable to CSV for audit trail generation.

Sample Compatibility & Compliance

The CNC2 accommodates flat, sheet, and block-form materials ranging from soft elastomers (Shore A 30) to semi-crystalline engineering thermoplastics (e.g., PEEK, PEI), fibre-reinforced laminates (carbon/glass/aramid), and thin metal foils (≤3 mm thickness). Specimen clamping is achieved via T-slot table fixtures or vacuum chucks (optional), ensuring zero slippage during high-feed-rate contouring. All machining parameters—including depth of cut, stepover, and spindle load—can be configured to meet specimen geometry tolerances specified in ISO 20753 (plastics), ASTM D3039 (composite tensile), and ISO 1133 (melt flow index sample prep). The system’s mechanical design and operational safeguards align with CE marking requirements under the Machinery Directive 2006/42/EC and electromagnetic compatibility per EN 61000-6-2/-6-4.

Software & Data Management

Operation requires an externally supplied Windows-based PC (not included) running FlashCut CNC v5.2 or later. The software provides offline program simulation, toolpath verification, and dynamic feed override controls. All executed jobs are logged with timestamp, operator ID (manual entry), G-code filename, spindle RPM, feed rate, and total cycle time—data exportable in .csv format for inclusion in GLP/GMP documentation packages. While the CNC2 itself does not incorporate built-in audit trail or electronic signature functionality, its deterministic G-code execution model allows full traceability when paired with validated laboratory information management systems (LIMS) or document control platforms compliant with FDA 21 CFR Part 11.

Applications

• Precision preparation of standardized test specimens for mechanical testing laboratories accredited to ISO/IEC 17025.
• Contour milling of irregularly shaped coupons for accelerated weathering, thermal cycling, or chemical resistance evaluation.
• Edge trimming and feature cutting of injection-moulded parts prior to microstructural analysis (SEM, optical microscopy).
• Manufacturing of calibration standards and reference geometries for coordinate measuring machines (CMM) and laser scanning systems.
• Rapid prototyping of functional test inserts for mould flow analysis validation and process qualification studies.

FAQ

Is the FlashCut CNC software included with the machine?
No—the CNC2 requires a separate Windows PC with FlashCut CNC software installed; the software license and hardware are procured independently.
What electrical infrastructure is required for installation?
A dedicated 220–240 VAC, 50 Hz, single-phase circuit rated for ≥16 A continuous load is mandatory, with proper earth grounding per IEC 60364-5-54.
Can the CNC2 cut metallic samples?
Yes—within defined limits: non-ferrous metals (aluminium, brass, copper alloys) up to 3 mm thickness using appropriate tooling and coolant strategies; ferrous metals require optional high-torque spindle upgrade and flood cooling.
Does the system support automated tool changing?
No—the CNC2 features a manual tool change interface; automatic tool changers are not available as standard or optional configurations.
Is technical support available outside the UK?
Yes—Ray-Ran provides global remote diagnostics and application engineering support through authorized distributors, with documented service level agreements (SLAs) covering response time and spare parts logistics.
