Power couplings are a critical part of a rotating machine for power transmission. Coupling flange joint is achieved by calibrated bolts working on shear stress. For this reason, it is important to perform machining on each hole on both flanges together, to get a perfect result in terms of co-axiality, diameter precision and roughness. This process is carried out by special low clearance boring machine and finishing by honing stones. Our small machine allows to work in a very small space between flange back-face and turbomachinery casing.
Working Range. Available to work on diameter up to 200mm, bigger ones by customization of equipment.
Special Add-ons and Customization. Always needed to match machine and work situation. Also available to work on bigger diameters.
