Features of a design and operation of the machine
The main distinctive feature of the machine consists that the machine has to process a difficult profile of end faces of details for welding concentric with a deviation of-0,8 mm in relation to a preparation profile, besides, that preparation has no correct cylindrical form.
Before processing "training" of the machine is made, i.e. the sensitive probe of the sensor installed on the faceplate of the boring grandma measures a detail profile in face section, feels an allowance at an end face and remembers the measured sizes. When processing the cutter established on the faceplate copies this form by means of the ChPU system on three coordinates, providing the set irregular shape of an external facet, internal facet and end faces of details according to drawings, with automatic installation of optimum number of passes.
Processing of two end faces of branches is made without reinstallation of a detail for what the special rotary table with a diameter of faceplate of 4600 mm is designed that allows to provide perpendicularity of end faces of branches to each other with high precision.
