Have you ever wondered how we make components that work in perfect sync with each other?


The requirement is to ensure that the dimensions of a part are accurate so that more complex systems can work together. To do this, reasoning in millimeters is completely irrelevant, you have to reason in microns, a thousandth of a millimeter. The micron is a measure that seems irrelevant but in our field can make the difference. To have a better idea of what a micron is, consider that the diameter of a human hair generally varies somewhere between 65 and 78 µm.

For such measurements, we decided to take advantage of the best on the market, namely Zeiss' technology. Our measuring equipment allows us to ensure surprising results: the tolerance margin of a measurement is in fact from 1.5μm to 1.8μm. It is so easy to see how the components of a compressor can really work in harmony with each other. To really understand the size, the diameter of a red blood cell is 8 microns.

How does it work?


The machine is equipped with a probe that comes into contact with the various points on the surface of the workpiece. Thanks to its passage and the use of specific software, the coordinates created by the movement are translated into actual measurements. We do not limit ourselves to the outlines of an object, but can also measure its internal parts. As a simple example, working on one of our cylinders, this metrological machine maps it point by point and also highlights values of roundness, taper and concentricity.

The aim is to provide unparalleled support and control capabilities to our production department. Absolute accuracy is fundamental when it comes to mechanical precision components, as is their repeatability.Investing in this type of machinery is vital to enable us to deliver an excellent product to you, allowing us to optimally simulate the behaviour of the various parts. We can thus guarantee continuous and perfect reproducibility of the various components of your Coltri compressor.
