Regenerative works carried out for the purpose of the power engineering sector require employment of specific personnel with much technical expertise. Appropriate technical consulting enables us, in conjunction with the maintenance department, to find and implement an optimal repair methodology. An indispensable part of most service-machining tasks performed by us are geometric measurements. Laser and optical settings of boring machines or checking the flatness of the surface allow us to keep high quality services and the necessary metrological self-control. Mobile machining, constituting an alternative to the stationary machines, and sometimes almost the only possibility of execution, carried out appropriately, each time allows to maintain the regime of implementation tolerance. The machining process carried out at the place of occurring of a failure in relation to the actual operating conditions of the damaged element and the causes of deformation, opens a vista for new, more effective technology.
