Prezenta inventie se refera la un dispozitiv portabil de strunjit frontal, în special pentru strunjirea inelara a suprafetei de etansare la placile tubulare cu tevile montate de la schimbatoarele de caldura. Dispozitivul este format dintr-un corp inelar, montat pe piesa de prelucrat cu niste pene înclinate, în care se roteste o coroana dintata care poarta un suport de ghidare, pe care culiseaza o sanie portcutit, în miscarea ei radiala, este antrenata de o coroana dintata ce antreneaza o roata dintata montata pe un arbore melcat angrenat cu o coroana melcata si care, printr-un butuc filetat, este legata de un surub de avans, montat în suportul unei scule aschietoare.The present invention relates to a portable frontal turning device, especially for ring-shaped turning of the sealing surface to tubular plates with pipes mounted from the heat exchangers. The device consists of an annular body mounted on the workpiece with some sloping edges in which a toothed crown that carries a guide support, which slides a harnessed slide in its radial movement, is trained by a crown a toothed tooth that is mounted on a worm gear engaged with a worn crown and which, through a threaded hub, is connected to a feed screw mounted in the support of a cutting tool.
Process for machining surfaces with irregular curvatures, for example, on punches, dies, hold-downs or other profiled parts of bulky tools, by grinding by means of a so-called grinding head or the like and device for the implementation of this process
