20110170964 | DRILLING TOOL AND DEVICE WITH SELF-MAINTAINED AXIAL VIBRATIONS - In order to effect drilling without any risk of blockage of the cutting tool used, a drilling device uses means for producing a self-maintained axial vibration of the tool that has the effect of breaking up the swarf of the material removed from the hole in order to facilitate discharge thereof. The means for producing the self-maintained axial vibration are also such that the spindle of the tool can have a direction substantially different from the rotation axis of the means used for rotating the tool. Such a device is particularly advantageous for producing deep holes or during the use of cutting tools producing asymmetric cutting forces. In a particularly advantageous embodiment, the means for producing the self-maintained axial vibration and for enabling the rotation axis of the tool to have a direction substantially different from the rotation axis of the drive means form part of the cutting tool. | 07-14-2011 |

20140169895 | PRECISION BORE MACHINE AND METHOD OF PRODUCING A PRECISE BORE - A bore machine for producing a very precise bore, as well as a method of producing a very precise bore in a workpiece. The bore machine has a main drive that drives the spindle rotationally as well as travel along the axial direction and an auxiliary drive that provides an oscillating motion in the axial direction that is overlayed over the forward travel motion of the spindle. The auxiliary drive has a first element with a wave-shaped surface and that is movable relative to a second element. During relative motion between the first and second elements, one element is forced to follow the peaks and valleys of the wave-shaped surface, thereby generating the oscillating motion. The auxiliary drive is driven such, that the relative motion between the two elements is at most 30% of the rotational speed of the spindle. | 06-19-2014 |
