Larger size CMMs

The Altera ceramic bridge coordinate measuring machine (CMM) range manufactured by Nikon Metrology has been extended by the introduction of high accuracy Altera+ models as well as larger size machines.

Now comprising 30 standard models and seven bridge sizes, the core Altera programme offers solutions for an array of applications and requirements, from the smallest measuring volume of the 7.7.5 model up to the largest, 60.20.15. The Altera+ series includes standard sizes ranging from the 8.7.6 to the 25.10.8 for inspection of critical components manufactured to the tightest of tolerances.

Thanks to optimised designs and the use of advanced materials, Altera provides high performance and accuracy across a host of metrology applications, including harsh shopfloor environments. Probing support is extended with Revo 5-axis scanning technology to improve CMM productivity dramatically for complex tactile inspection applications. Notably, Altera is delivered with a manufacturer’s ten year accuracy guarantee.

Built and designed to exacting standards, Altera CMMs use advanced ceramic components for structural integrity and enduring performance. With near perfect stiffness to weight ratio, ceramic guideways facilitate impressive accuracy: 1.4+L/375 (E150 according to ISO10360-2:2009). The ceramic bridge is resistant to temperature variation, while the stress free, horizontal ceramic beam and advanced multi-point bearings counter any negative effect on accuracy when using long probes.

These CMMs support an extensive range of tactile and non-contact probing and software options. Multi-sensor technology extends capability to measuring parts that are large or small, 2D or 3D, hard or soft and prismatic or freeform. Software options consist not only of Camio and CMM-Manager, but also Modus to operate the Renishaw Revo-2 probe head.

The shopfloor-ready Altera CMM makes use of several innovative new features. Folding guideway covers protect the air bearing guideways from airborne contaminants such as dust and oil. Superior pneumatic, self-levelling vibration isolators provide optimum performance in areas subject to high levels of low frequency vibration. Automation can integrate machine tools, transfer systems and material handling to form flexible manufacturing systems.
