20120219370 | CUTTING TOOL, IN PARTICULAR PARING TOOL, DRILL HEAD, SOLID DRILL HEAD OR BORING HEAD, AND CUTTING MACHINE AND METHOD - Rotationally symmetrical bodies consisting of metal materials must often be provided with cylindrical drilled holes following a central and straight progression. These drilled holes extend in part over the entire length, so that drilling yields a tubular body. If drilled holes with a depth>10 times the average are needed, deep drilling machines are used. This drilling depth combined with structural details may give rise to deviations from the drilling axis and work piece axis. This may lead to scrap. Therefore, the invention proposes a core drill head or solid drill head that exhibits a directional controller for use in deep drilling machines. | 08-30-2012 |
20110206304 | Rolling body guide with a separately exchangeable rolling body as well as a receiving section and a rolling tool with an associated exchange method - More specifically during manufacture of hydraulic cylinders for the crane industry, tubular bodies must be rolled on their inner and/or outer surfaces, in order to be able to ensure a sufficient durability of the hydraulic cylinders. Tools with a rolling body guide are used for this. The disadvantage of the prior art is that the replacement of a rolling body guide leads to immobilization times. The present invention therefore proposes an improvement to the prior art with a rolling body guide for receiving and feeding rolling bodies which are used for finish rolling or roller compression of an inner or outer surface of a tubular body and where the rolling body guide has at least two defined detachable receiving sections, so that a modular assembly of the rolling body guide is realizable. | 08-25-2011 |
