LK Metrology Gantry Coordinate Measuring Machines
Large-volume components demand large-volume certainty. When dimensional tolerances on aerospace structures, heavy castings, or full-scale assemblies cannot afford ambiguity, the inspection system must match the scale of the task – without sacrificing accuracy.
LK Metrology’s gantry coordinate measuring machine (CMM) range delivers exactly that. Built on bonded ceramic and aluminium construction with high-efficiency air bearings, zero-hysteresis friction drives, and multi-sensor thermal compensation, the Aeros platform maintains micron-level measurement stability across volumes up to 8 metres – backed by LK Metrology’s 10-year original accuracy guarantee.
LK Metrology Range of Gantry CMMs
Micron-level measurement stability across large-volume inspection tasks – where component scale, weight, and geometric complexity leave no room for uncertainty.
Aeros
Not every large-volume inspection task demands heavyweight construction.
The Aeros delivers micron-level gantry CMM accuracy through lightweight aluminium alloy – keeping moving mass low and measurement dynamics high across 22 standard model configurations.
- Aluminium alloy Z-spindle and Y-crossbeam for an optimised stiffness-to-weight ratio and consistent measurement performance
- Multi-sensor thermal compensation automatically corrects for structural expansion across variable temperature conditions
- Operational speeds up to 500 mm/s with acceleration up to 1200 mm/s² for high-throughput inspection cycles

Aeros S
When measurement volumes grow beyond what a standard gantry can manage, the Aeros S steps in.
A proprietary steel tubular Y-crossbeam and stabilised steel X-beams replace aluminium where rigidity matters most – giving you structural stability that holds across extended spans.
- Steel X-axis beams with wide transverse sections, designed to expand linearly without inducing deformation
- Dual-Read X-axis measurement system with 0.1 µm linear transducers for enhanced precision on long travels
- Dual-Drive X-axis as standard on Y-sections of 3000 mm and above – optional on smaller configurations

Aeros P
When components reach the scale of aerospace structures, marine engines, or turbine assemblies, the Aeros P holds accuracy where other gantry CMMs begin to flex.
Coupled Dual-Drive and Dual-Read X-axis systems actively minimise structural deformation across every metre of travel.
- Stabilised steel X-beams with wide cross-sections and a support system that accommodates linear thermal expansion without inducing stress or deformation
- Rack and pinion drive on both X and Y axes for precise, efficient movement of the heaviest gantry configurations
- 0.1 µm high-resolution linear transducers with integrated multi-sensor thermal compensation for consistent accuracy across the full measurement range
