New range of cost-effective large-volume gantry CMMsAn LK Metrology AEROS P large-capacity co-ordinate measuring machine

Derby-based LK Metrology Ltd, a coordinate measuring machine (CMM) manufacturer, has introduced a third series of large-capacity models to sit alongside its established bridge-type and large-scale gantry-type CMMS, which offer extremely high accuracy due to their ceramic moving guideways.

Using the latest innovations in aluminium and steel CMM guideway technology, the new AEROS, AEROS S and AEROS P gantry-type CMMs ¡X 40 models in total ¡X lower the capital cost of such equipment. With measuring volumes up to 8.0 x 3.5 x 2.5m, they allow a broader spectrum of manufacturers in industries such as aerospace, power generation, automotive and defence to benefit from the latest 3-D metrology systems.

Unlike traditional bridge CMMs, the AEROS main structure of support pillars and longitudinal guideways remains static, with only the gantry beam assembly moving during measurement. The open design is extremely adaptable, providing full access to the work area during loading and unloading of parts. It is particularly well-suited to ¡¥smart¡¦ factories with autonomous guided carts and manually-operated wheeled or rail-type material handling systems.

For consistent accuracy and dimensional stability, innovative design features have been incorporated into the AEROS range to minimise distortions and errors of inertia. Particular attention has been paid to the design of the guideway support system, which allows the longitudinal beams to freely expand without risking distortion.

Multiple thermistors are fitted for automatic compensation of errors due to thermal expansion of structural components in uncontrolled environments, such as production areas. Extra-wide air bearing tracks and generous dimensioning of the distance between air bearings provides optimal mechanical rigidity. 0.1µm optical linear scales provide accurate positional feedback and precise motion control, with a dual-readhead system on both X-axis guideways for excellent metrology performance.

The AEROS range of machines offers a medium to large measuring volume, with configurations in a wide range of sizes to meet the requirements of large-scale metrology applications. 14 standard models span Y/Z axis travels of 2.0/1.0m to 2.5/1.8m, the X-axis being from 3.0 to 6.0m.

A micro-machined, advanced alloy, Y-axis cross-beam and lightweight extruded aluminium Z-axis spindle ensure a high degree of stability while reducing the effect of inertia. Zero hysteresis friction drives are employed for the Y and Z axes, while a robust rack and pinion drive is used for X-axis movements. Measuring accuracy is from 5.5+6.0L/1,000µm, while maximum 3-D speed and acceleration are an impressive at 500mm/sec and 1,200 mm/sec2 respectively.

LK MetrologyAEROS S machines cover measuring volumes dictated by Y/Z axis travels from 2.5/1.8 to 3.0/2.0m and an X-axis up to 6.0m - and there are 12 standard models to choose from. They are similar in construction to AEROS machines and offer nearly equivalent attributes but have a cross-beam of stabilised tubular steel construction.

A dual-drive X-axis is standard over 3,000mm. Both the X and Y axes employ a rack and pinion drive system while the Z-axis features a zero hysteresis friction drive. Accuracy and maximum 3-D speed range from 7+8L/1,000µm and 530mm/sec respectively, with 3-D acceleration at 800mm/sec2.

AEROS P machines consist of 14 standard sizes, similar again except that they feature coupled dual-drive and dual-readhead positioning in the X-axis to minimise structural deformation during movement, guaranteeing excellent metrology performance.

Measuring accuracy, speed and acceleration are the same as for the AEROS S. Y/Z axis travels are from 2.5/2.0m to 3.5/2.5m and the X-axis is up to 8.0m. Both the X and Y axes employ a rack and pinion drive while the Z-axis features a zero hysteresis friction drive.

A full range of probing options is offered to suit all types of metrology application, including multi-sensor technology, touch trigger probes, scanning probes, laser scanners and five-axis probe systems.

On offer also is an advanced array of software, including LK CAMIO 2021 measurement, programming, analysis and reporting software, while the Industry 4.0 Metrology Gate portal provides remote access to quality data and CMM status from any internet-connected device anywhere in the world.

LK Metrology’s offering is rounded off by a wide range of options including CMM automation, rotary tables, enclosures and customer services.
