LK Metrology Bridge-Type CMMs Enable Precise Measurement of Large, Heavy Components

Why It Matters

The new CMMs let aerospace, automotive and energy manufacturers measure massive, high‑value parts with micron‑level precision while cutting installation costs and downtime, accelerating quality‑control cycles.

Key Takeaways

• Up to 72 m³ measurement volume, largest granite CMM
• Accuracy down to 3 µm with ceramic guideways
• Twin‑rail Maxima R eliminates need for special foundations
• Supports tactile, laser, and five‑axis scanning probes
• Enables automated loading of heavy workpieces up to 3 m

Pulse Analysis

Large‑scale manufacturing has long struggled with the trade‑off between component size and measurement precision. Traditional bridge‑type CMMs often require massive foundations and still fall short on volume, limiting their use in sectors such as aerospace wing assembly or wind‑turbine blade production. LK Metrology’s Maxima series disrupts this paradigm by delivering a 12–72 m³ granite table—the biggest on the market—while maintaining a 3 µm repeatability. The combination of ceramic guideways and low‑gap air bearings creates a high stiffness‑to‑weight ratio that preserves accuracy even under heavy loads, positioning the machines as a benchmark for next‑generation metrology.

The engineering choices behind the Maxima R twin‑rail design address two critical pain points: installation complexity and workflow efficiency. By eliminating the need for custom foundations, plants can repurpose existing floor space and reduce capital expenditures. The open‑rail architecture also simplifies the integration of automated transfer systems, allowing robots or gantry loaders to safely position multi‑ton components without manual intervention. This foundation‑free approach shortens commissioning time and improves overall equipment effectiveness, a decisive advantage in high‑throughput environments.

Beyond hardware, LK Metrology equips the CMMs with a flexible probe ecosystem. Operators can switch between the PH10MQ Plus tactile probe, the Revo2 five‑axis scanner, or the SP80 fixed scanner, all supported by a unified multi‑wire cable that carries both SLK and L/LC/XC laser‑scanner signals. This versatility enables manufacturers to perform detailed dimensional checks, surface scans, and complex geometry inspections on a single platform. As industries push toward larger, lighter, and more intricate components, the Maxima and Maxima R families provide the precision, scalability, and integration capability needed to keep quality assurance ahead of design innovation.
