LK Libero raises the performance standard for bridge CMMs
The LK Libero is a new generation CMM focusing at fast and accurate inspection tasks. The machine, with it’s distinctive raised guide way, is a high performance CMM, aimed at the high accuracy- high throughput market dominated by the automotive and aerospace industries. Featuring a granite table, a ceramic beam and spindle, the Libero continues the tradition of providing metrology structures that provide stiffness & stability with drive systems that offer smooth & efficient motion control to users requiring very high accuracy, reliability & low cost of ownership.

The Libero has two distinctive design features that provide much greater stiffness to the metrology structure. A characteristic that is vital in quick and successful high accuracy scanning. In raising the X-axis guideway the drive has been positioned much closer to the centre of gravity and coupled with the inclusion of an S-Axis scale to dynamically compensate for X Axis errors this has created a significant increase in the stiffness of the structure. Initial testing of the Libero on shopfloor benchmarks resulted in a doubling of the capability index on many of the measured features when compared to a metrology lab machine located in a temperature controlled and clean environment.
Libero CMM

Primarly designed as an analogue scanning solution, the Libero is a significant development in the marketplace. For the first time it provides a CMM with the high performance scanning characteristics, previously only reached in the metrology lab, into the shopfloor environment and provides them without the need to provide expensive and restrictive enclosures.
 
The new CMM will be available in three machine variants and all of them are fitted with temperature compensation and pneumatic AVM’s as standard. The Libero Ultra is designed to be a very high accuracy laboratory machine but the Libero & the Libero Therma are designed for shopfloor use with the Therma having a guaranteed temperature range of 15 to 30ºC making it suitable for very high performance in a hostile thermal environment.
