Granite is one of the natural materials with the lowest thermal expansion coefficient in the world, a very important quality when it comes to measurement.
Natural granite is an igneous rock generated by solidification of a magmatic mass in the Earth's mantle. This process lasts millions of years which gives granite the particular properties regarding technological stability not found in other rocks.
Elbo Controlli NIKKEN is the only manufacturer of pre-registration, measurement and inspection tools machine (presetting machine) to use natural granite as a building material. It is also the first and only presetter with granite scales.
During the 2018 BIMU tradeshow in Milan, the new E68LA presetter machine model was presented, which completes the range of products offered. The most important novelty is the introduction of the optical scales with granite ruler and graduated optical glass that equip all the E68 presetter series (X and Z axes), a real revolution from a technological point of view.
These two types of materials (granite/glass) are highly compatible, as they have an almost identical thermal expansion coefficient. The processing technology makes the granite surface perfectly flat, in order to apply the measuring optical glass scale without any deformation.
The reader head (GA) has also been redesigned: particular attention was paid to the mechanical design of the movable slider, to simplify the structure and significantly reduce the backlash.
The new GS371 granite optical scale is a unique solution in the measurement sector: it’s a high precision, thermally stable and free from mechanical calibration measuring system.
How is possible to guarantee certain unparalleled precision and performance? Simple, by studying and creating a dedicated fastening tool and testing, with strict procedures, every single element through electrical and mechanical tests. Elbo Controlli NIKKEN has developed and patented an extremely precise gluing system, thus avoiding the introduction of coupling errors between the two materials.
The Elbo Controlli NIKKEN philosophy is to simplify the operator work as much as possible: for this reason, our products are performing, precise and easy to use. This is why Elbo Controlli NIKKEN has decided to invest time and resources in high-level technologies, developing unique and ad hoc solutions for this type of application.
