Advanced design and superior materials for maximum performance in any application

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, with greater resistance to temperature shifts, makes the ALTERA suitable for metrology applications in a host of manufacturing and shop floor environments. The stress-free horizontal ceramic beam and advanced multi-point bearings counter any negative effect on accuracy when using long probes.

Multi-sensor technology for the broadest range of metrology applications

ALTERA CMMs support an extensive range of tactile and non-contact probing and software options. Multi-sensor technology extends the ALTERA capability to measuring parts which are large or small, 2D or 3D, hard or soft and prismatic or free-form. With almost 30 different models and 7 bridge sizes, the ALTERA offers solutions for an array of applications and requirements. The extended sizes range from the smallest measuring volume - 7.7.5 to the largest – 60.20.15, of the standard sizes available. Software options consist not only of CAMIO and CMM-Manager, but also MODUS – to operate the Renishaw REVO-2 probe head.

Ready for shop floor use

The shop-floor-ready ALTERA CMM makes use of several innovative new features. Folding guideway covers protect the air bearing guideways from airborne contaminates 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 capability for manual or fully automated FMS production cells, can integrate machine tools, transfer systems and material handling.

Unique accuracy guarantee – Nikon Metrology are the only manufacturer to guarantee the accuracy of their CMMs for 10 years.

Accuracy of the ALTERA is fully ISO 10360 compliant, and comes with the Nikon Metrology 10 year original accuracy guarantee – demonstrating the utmost confidence in the quality and reliability of the ALTERA. With over 50 years of experience and close collaboration with its large customer base, the ALTERA builds on foundations of high quality, exceptional stability and enduring performance.
