20100048104 | METHOD FOR GRINDING A MACHINE PART, AND GRINDING MACHINE FOR CARRYING OUT SAID METHOD - Disclosed is a method for grinding a machine part that is used as a drive shaft, for example, rotates about the longitudinal axis thereof during the grinding process, and is provided with a journal at one axial end thereof and a recess at the opposite end thereof. The grinding process is carried out in one and the same grinding machine. In said grinding method, the machine part is brought into different clamped states by means of a chuck of a workpiece spindle head with releasable clamping jaws and a centering tip, a backrest, and/or a tailstock quill. Changing the clamped states has the advantage that the machine part remains in the same position in a single grinding machine, i.e. the clamped position, in all the different clamped states such that more accurate sizes, shapes, and positions can be obtained in an economical manner and all areas of the machine part which are to be ground are successively accessible to the grinding disks. | 02-25-2010 |

20130029564 | PROBE PIN AND METHOD OF MANUFACTURING THE SAME - A probe pin having a bent portion at its tip end portion is used for a probe card, the probe pin is configured such that an angle constituted by a direction of work groove generated at a time of machine-working of a tip end portion of the probe pin and a longitudinal direction of a metal wire is set to 45 degree or less, or both directions are set to be almost parallel to each other. Due to above configuration, even if the tip end portion of the probe pin is subjected to a bending work and a worked surface is formed with recessed portion, a breakage of the probe pin caused by the recessed portion existing on the worked surface and functioning as a starting point of the breakage can be effectively prevented whereby a lowering of a production yield of the probe pin can be greatly suppressed. | 01-31-2013 |
20130165022 | CENTRELESS CYLINDRICAL GRINDING MACHINE FOR GRINDING WORKPIECES IN ROD FORM AND METHOD FOR THE CENTRELESS CYLINDRICAL GRINDING OF WORKPIECES IN ROD FORM - In a machine for centreless cylindrical grinding, the workpiece is located in a grinding gap, which is formed by the regulating wheel, the grinding wheel and the support blade. The regulating wheel rotates about its axis of rotation with the direction of rotation, and thereby drives the workpiece to rotate in the direction of rotation. The grinding wheel is driven to rotate about its axis of rotation with the direction of rotation. The workpiece passes in the direction of its longitudinal axis through a number of sets of regulating wheels and grinding wheels, which are each themselves arranged coaxially one behind the other. The regulating wheels and grinding wheels have axial interspaces on their axes; the regulating wheels thereby engage in the interspaces between the grinding wheels, and vice versa, so as to form lateral regions of overlap between the wheels. | 06-27-2013 |
20130210322 | METHOD FOR THE CYLINDRICAL GRINDING OF A WORKPIECE, SYSTEM CONTAINING THE WORKPIECE AND APPARATUS FOR THE CENTRELESS GRINDING OF THE SYSTEM - On a workpiece there are first longitudinal portions which are rotationally symmetrical with respect to the continuous longitudinal axis and are intended to be ground by way of centerless grinding. The workpiece also has a second longitudinal portion, which is not rotationally symmetrical with respect to the longitudinal axis and would lead to imbalance in the event of rotation. Therefore, a balancing weight having a radially extending recess is placed on the second longitudinal portion. The balancing weight contributes largely to uniform distribution of the rotating masses, thus reduces the imbalance to a very low residual imbalance and allows reliable and precise centerless grinding. | 08-15-2013 |
