This means the pins are interchangeable so slotted pieces can also be turned.  The extraordinary driving efficiency of  F.R.B. face drivers means that the full state-of-the-art performance of even the most advanced machine tools can be fully exploited. <\/p>\n<p><hr class=\"no_line\" style=\"margin: 0 auto 0px auto\"\/>\n<br \/>no-repeat;left top;;<br \/>auto<\/p>\n<p>Immagine tecnica<br \/><img decoding=\"async\" src=\"\/wp-content\/uploads\/2020\/09\/trascinatore-frb.jpg\" alt=\"\"><br \/>center<br \/>#e2f4fb<br \/>no-repeat;left top;;<br \/>auto<\/p>\n<p>Tutti i trascinatori FRB sfruttano<br \/><hr class=\"no_line\" style=\"margin: 0 auto 0px auto\"\/>\n<br \/>\n<br \/>All F.R.B.

These reduce pin deflection.The wedge lever assembly has two balancing plates that are held in position by two elastic elements called \u201canchors\u201d which are attached to the underside of the balancing plates themselves.<\/p>\n<p>The four driving pins are guided by the driving pin support washer and their rotation play is eliminated by the driving pin retaining screw. The driving pins rest their rounded end on the balancing plates of the wedge lever, which has been specially designed to compensate any obliqueness of the end faces on which the driving pins rest. They are made from a special Vanadium and Molybdenum steel which is exceptionally resilient and hard. Furthermore, the driving pins are of two types, one for each direction of the spindle\u2019s rotation.<\/p>\n<p>The centre point is independent of the driving pins and is loaded by the Belleville springs whose thrust may be adjusted using the grub screw at the back of the face driver, inside the cone.<\/p>\n<p>Bored pieces or large centres may be machined by fitting slotted pins. Lowered driving pins can be fitted to all models in order to work on diameters which are too small to be turned by standard size driving pins, from the face driver\u2019s side.<\/p>\n<p><hr class=\"no_line\" style=\"margin: 0 auto 0px auto\"\/>\n<br \/>no-repeat;left top;;<br \/>auto<\/p>\n<p>Immagine tecnica<br \/><img decoding=\"async\" src=\"\/wp-content\/uploads\/2020\/09\/trascinatore-frontale-frb.jpg\" alt=\"\"><br \/>center<br \/>#e2f4fb<br \/>no-repeat;left top;;<br \/>auto<\/p>\n<p><hr class=\"no_line\" style=\"margin: 0 auto 0px auto\"\/>\n<br \/>\n<\/p>\n<h4>THE FRB FACE DRIVER<\/h4>\n<p>Enables the operator to change the driving pins and the centre point quickly and without having to remove other driver components.
