Overview
The Hexagon Metrology Croma Classic Coordinate Measuring Machine (CMM) is a fully automated, high-reliability metrology platform engineered for precision geometric measurement in mid-volume manufacturing and quality control environments. Built upon the proven mechanical architecture of the Croma family, it employs a kinematic three-axis orthogonal structure operating on the principle of point-cloud acquisition via tactile or optical probing—enabling traceable dimensional verification of complex parts per ISO 10360 and VDI/VDE 2617 standards. Its design prioritizes thermal stability, mechanical repeatability, and long-term measurement integrity under typical factory-floor conditions (20 ± 2 °C, humidity < 60 % RH). The system integrates seamlessly into production workflows requiring compliance with ISO 9001, IATF 16949, and AS9100 quality management frameworks.
Key Features
- Monolithic aluminum frame construction: Uniform coefficient of thermal expansion across structural components enables predictable, linear thermal drift—facilitating effective real-time temperature compensation using integrated sensors.
- Critical fasteners and mechanical interface components sourced from certified European suppliers to ensure consistent preload behavior, torsional rigidity, and long-term joint integrity.
- High-tensile German-manufactured polyurethane timing belts with embedded stainless-steel tension cords: Deliver precise synchronous motion transmission while minimizing axial backlash and vibration during rapid traverse (up to 500 mm/s), supporting high-speed scanning without loss of path fidelity.
- Modular probe system compatibility: Supports both Hexagon’s own PH10M/MH20i indexing heads and industry-standard TP20/TP200 touch-trigger probes, as well as optional RENISHAW SP25 scanning modules for continuous surface capture.
- Industrial-grade granite base with precision-machined kinematic mounting pads: Provides stable foundation geometry and decouples machine dynamics from floor-borne vibrations.
Sample Compatibility & Compliance
The Croma Classic accommodates workpieces ranging from small precision components (e.g., injection-molded plastic housings, machined brackets, gear blanks) up to medium-sized castings and sheet-metal assemblies (max. envelope: 700 × 600 × 600 mm, depending on configuration). It supports measurement of GD&T characteristics including position, profile, concentricity, parallelism, and true position—fully compliant with ASME Y14.5 and ISO 1101. All calibration and verification procedures adhere to ISO 17025-accredited methodologies when executed by certified service personnel. System documentation includes full traceability to national metrology institutes (NIM, PTB, NIST) via certificate-of-calibration chains.
Software & Data Management
The Croma Classic ships standard with Rational-DMIS v7.x—a Windows-based metrology software platform validated for FDA 21 CFR Part 11 compliance (audit trail, electronic signature, role-based access control). Optional PC-DMIS licensing is available for users requiring deeper integration with enterprise PLM or MES systems (e.g., Teamcenter, Windchill, SAP QM). Both platforms support ISO 10360-6 compliant reporting, automated report generation in PDF/XML formats, and bidirectional CAD data exchange via STEP AP214 and IGES. Measurement programs are version-controlled, exportable, and compatible with Hexagon’s QUINDOS ecosystem for centralized fleet monitoring and SPC analysis.
Applications
This CMM serves critical inspection roles across automotive Tier-1 suppliers (bracket validation, weld fixture verification), aerospace subcontractors (engine mount interfaces, ducting geometry), medical device manufacturers (implant mating surfaces, sterilization tray features), and mold & die shops (cavity alignment, electrode wear tracking). Its balance of accuracy (MPE E₀ = 2.5 + L/300 µm per ISO 10360-2), throughput, and operational robustness makes it particularly suited for first-article inspection, process capability studies (Cp/Cpk), and periodic gage R&R assessments in GLP/GMP-aligned laboratories.
FAQ
Is the Croma Classic certified to international metrological standards?
Yes—it conforms to ISO 10360-2 for length measurement error and ISO 10360-6 for probing error, with factory verification performed under controlled environmental conditions and documented in the delivered Certificate of Conformance.
Can the system be integrated into an Industry 4.0 production line?
Absolutely. With OPC UA server support and RESTful API endpoints, the Croma Classic enables real-time measurement data streaming to SCADA, MES, or cloud-based analytics platforms for closed-loop quality feedback.
What level of technical support and calibration services are available globally?
Hexagon Metrology provides tiered support packages—including remote diagnostics, on-site preventive maintenance, and accredited recalibration services through its global network of ISO/IEC 17025-certified service centers.
Does the system support multi-sensor configurations beyond tactile probing?
Yes—optional vision modules (e.g., Hexagon Inspire Vision) and laser line scanners can be retrofitted to enable hybrid measurement strategies for mixed-feature parts.
