Monorail guides (rails and carriages) / telescopic guides for door systems in trains and for furniture structures (U-sections with rollers slots / profiles for sliders) / other sliding guides for heavy loads (eg. in marbleworking machines) / mini-guides for printed circuits’ and semiconductor industry /


Linear motion is a booming sector following on from the general and ongoing trend of automatization of machinery and equipment. In the field of linear motion, as for any kind of guides and rails, the use of long steel profiles is particularly indicated: the solutions guaranteed by Calvi Network as regards the stability of the geometries, the mechanical properties of the profiles and their perfect straightness best fit the requirement of linear guides manufacturers and the steel forming technology, esp. cold drawing, often results far more economical compared to other traditional manufacturing alternatives (esp. turning and milling).


Case History

The Network has been cooperating for more than 30 years with the most qualified European manufacturers of linear systems. In the field of linear motion, Calvi Network has always been indeed a premium partner – from the engineering step, going through the material definition and manufacturing cycles – able to satisfy process and product co-engineering. Calvi adapted its equipment, oriented its investments and codified its processes on the basis of the needs and requirements of its customer.
The shape for a monorail guide remained the same since it’s been first supplied but – over time – the relationship and the collaboration enabled to reach major technical improvements and consequent economic advantages for the customer: straighter bars, optimized tolerances, improved and constant mechanical properties.
