ABSTRACT:
The invention relates to an improved micrometric device for finishing high precision bores. The device has a substantially cylindrical body having a displacement system arranged in an interior thereof. The displacement device actuates on a tool holder which is then displaced in the same direction of the radial component of the workforce. The micrometric device is also provided with a backlash suppression system. In accordance with the present invention, the micrometric device has an upper cylindrical body mounted and fixed to a lower cylindrical body, both of which coaxially envelop a graduated drum. The graduated drum, in turn, is coaxially mounted and connected to a micrometric screw arranged longitudinally in the interior of the micrometric device. In the interior of the micrometric device, and connected to an upper extension of the micrometric screw, a conversion mechanism is arranged which changes a rotating movement of the micrometric screw into a linear movement of a movable crossbeam. The crossbeam is indirectly connected to the micrometric screw and supports the tool holder and respective cutting tool.
