Finishing boring bar

insert

One of the flagships of our production are the mechanically fastened boring bars , usually used in the automotive sector and in the production of large batches. The boring tool , often made up of several insert seats, allows the machining of diameters , chamfers , radii , counterbores and shaped profiles at the same time with a single tool. The use of a combined boring tool allows a reduction in machining times , thanks to shorter machine setup and tool change times. The practicality of this tool has made it an indispensable work tool not only for large productions, but also for the most current small series. On the basis of the amount of stock to be removed , the type of machine and material to be processed, our team studies the optimal work cycle and consequently the tools necessary for production. In this way, roughing boring bars are designed that are able to remove most of the stock on the piece, thus preparing the surface for the subsequent passage of the finishing boring bars. These allow centesimal accuracies and finishes with reduced roughness to be achieved. Depending on the requirements , the boring bars can be made with a fixed seat, cartridge seat or with micro-boring units . These latter elements are supplied together with the boring machine to offer a complete turnkey package. Should it be necessary, due to space constraints or the need to use a shaped insert, our production makes special tailor-made cartridges. Items can be made with theconnection required by the customer: cylindrical, Weldon, Whistle Notch, Varilock, BT, ISO DIN 69871, to modular ones made from semi-finished products.
