ALTO is a compact CMM with space-saving features such as the half-gantry design, fully integrated electronics and retracting monitor arm, making ALTO the perfect fit where space is limited.

Supplied with automated stylus changing as standard, ALTO is available with a standard motorised indexing probe head, or the latest high-performance 5-axis probe system for maximum efficiency.

With access from 3 sides for part loading, ALTO is ideal for production areas or quality control rooms.


ALTO employs high-tech aluminium alloy for the structure and guideways of its moving half-gantry. This cost-effective materials technology provides the stiffness needed for accuracy, while keeping ALTO’s moving mass to a minimum for high-speed measurement. Each guideway is micro machined and hard anodised, resulting in mechanically precise guideways that are resistant to wear and corrosion.

Hard Anodizing

Oxide layer coat
  • Electrolysis process for aluminium and its alloys
  • Similar coating to that of case-hardened steel
  • Greater resistance to wear and corrosion
  • Increases the naturally occurring oxide film
  • Layer coat up to 50µm in depth
