Overview
The Hexagon Metrology CROMA PLUS is a high-precision, moving-bridge coordinate measuring machine (CMM) engineered for large-part metrology in demanding industrial environments. Designed on the foundational mechanical architecture of the proven CROMA series, the PLUS variant extends volumetric measurement capability to up to 2000 × 4500 × 1500 mm (X × Y × Z), with custom configurations available beyond standard envelope dimensions. Its moving-bridge kinematic configuration delivers optimal stiffness-to-weight ratio and thermal stability across extended travel ranges—critical for maintaining sub-micron repeatability during long-duration inspections of massive components. The system operates on the principle of Cartesian coordinate acquisition via tactile probing and high-speed optical scanning, conforming to ISO 10360-2 (length measurement error) and ISO 10360-8 (scanning performance) verification protocols. It is purpose-built for applications requiring traceable geometric dimensioning and tolerancing (GD&T) evaluation—including form, profile, orientation, location, and runout—on parts weighing up to 8,000 kg.
Key Features
- Robust all-aluminum frame structure with 60° precision triangular bridge design and monolithic dovetail X-axis guideway—minimizing deflection and enhancing dynamic stability during high-speed scanning.
- Hexagon X1 dual-mode sensor integration (switchable scanning and triggering within single probe body), enabling seamless transition between discrete point capture and continuous surface digitization.
- Scanning module compliant with DCC (Direct Computer Control) architecture, supporting real-time path correction and adaptive sampling density based on local surface curvature.
- Extended-reach probe configurations with stylus lengths up to 225 mm—facilitating deep cavity and recessed feature access without repositioning.
- Compact 30 mm-diameter scanning head with integrated collision detection and automatic recovery logic—reducing downtime and safeguarding sensor integrity.
- Base-level volumetric accuracy starting from 2.0 µm (MPEE0,MPE per ISO 10360-2), validated under controlled environmental conditions (20 ± 1 °C, humidity ≤ 60 % RH).
Sample Compatibility & Compliance
The CROMA PLUS accommodates workpieces ranging from battery enclosures and EV structural assemblies to wind turbine gearbox housings and aerospace tooling fixtures. Its open gantry layout permits loading of irregularly shaped or oversized components via overhead crane or hydraulic lift table. The system meets ISO/IEC 17025 requirements for calibration laboratories when operated within defined environmental envelopes and supported by documented uncertainty budgets. All hardware and firmware comply with CE marking directives (EMC 2014/30/EU, Machinery Directive 2006/42/EC). Optional upgrades support FDA 21 CFR Part 11-compliant audit trails and electronic signature workflows when paired with PC-DMIS Premium or Rational DMIS Enterprise editions.
Software & Data Management
Two industry-standard metrology software platforms are fully supported: PC-DMIS and Rational DMIS. PC-DMIS offers extensive GD&T evaluation libraries, automated report generation (PDF, Excel, HTML), and native integration with Hexagon’s QUINDOS and METRILIB databases for enterprise-level SPC and MSA analysis. Rational DMIS provides advanced scripting (Rational Script), parametric programming, and customizable UI layouts—particularly advantageous for high-mix, low-volume production lines requiring rapid program adaptation. Both platforms support ISO 10360-8 certified scanning validation routines, measurement plan version control, and secure role-based access management aligned with GLP/GMP documentation standards.
Applications
Primary deployment sectors include electric vehicle battery pack manufacturing (cell housing flatness, weld seam geometry, mounting hole position), automotive die and fixture verification (tooling alignment, datum reference frame validation), precision heavy machinery components (gearbox bore concentricity, flange face perpendicularity), and renewable energy infrastructure (nacelle casting dimensional fidelity, blade root interface inspection). The CROMA PLUS serves as a cost-optimized alternative to龙门-type CMMs—requiring only standard reinforced concrete flooring (no deep pit or seismic isolation), lower facility footprint, and simplified HVAC load management due to its thermally stable aluminum construction.
FAQ
What is the maximum part weight the CROMA PLUS can accommodate?
Up to 8,000 kg, subject to table load distribution and center-of-gravity constraints.
Does the system support automated temperature compensation?
Yes—integrated thermal sensors monitor ambient, granite table, and bridge temperature; real-time compensation is applied using material-specific coefficients per ISO 10360-3.
Can the CROMA PLUS be relocated after initial installation?
Yes—the modular base and bridge assembly allow disassembly, transport, and reinstallation with full recalibration and ISO 10360 verification.
Is remote diagnostics and software update support available?
Hexagon ServiceLink enables secure remote connectivity for predictive maintenance alerts, firmware updates, and collaborative troubleshooting with certified metrology engineers.
What metrological standards does the CROMA PLUS comply with out-of-the-box?
ISO 10360-2 (static length measurement), ISO 10360-8 (scanning performance), VDI/VDE 2617-9 (geometric errors), and ASME B89.4.1-2013 (CMM performance evaluation).
