20080232916 | Process and Device for Producing Threads, Especially for Boring Rods or the Like - The present invention proposes a process for producing threads, especially for boring rods or the like, wherein the workpiece and the lathe tool have a relative rotary motion at a high velocity about an axis of the workpiece and a relative longitudinal motion at a low velocity compared to the above velocity, and wherein an oscillating radial relative rotary motion is brought about, furthermore, between the lathe tool and the workpiece, wherein the radial oscillating motion is generated mechanically, the radial oscillating motion being synchronized, in particular, with the relative rotary motion. The present invention pertains, furthermore, to a device for producing threads by a means for generating the radial mechanical oscillating motion, where the radial oscillating motion is synchronized, in particular, with the relative rotary motion. | 09-25-2008 |
20100166518 | Method And Apparatus For Machining Work Pieces - A method and apparatus are provided to machine a curved surface such as an inner or outer peripheral surface of a pipe. The pipe is held stationary during machining and a rotatable spindle of a machine head moves along multiple orthogonal axes to align the rotational axis of the spindle with the longitudinal pipe axis. Preferably, the pipe axis is located by using a touch probe to engage the curved surface at multiple spots and the calculating the location of the pipe axis. The cutting tool, which is preferably a cutting tool insert, is rotated by the spindle to machine the curved surface. | 07-01-2010 |
20110211925 | Method for Generating a Thread by a Tool machine, Coupling Device and Tool Machine - The invention relates to a method for generating a thread by a numerically-controlled tool machine (or: machine tool) using a thread generation tool, the thread generation tool being rotated by a tool spindle and simultaneously advanced according to the thread pitch in the axial direction, in order to generate a thread in a borehole of a workpiece. In order to increase the working velocity of the thread generation, the invention provides that the rotational velocity (ω | 09-01-2011 |
20140112729 | Method for Producing and Checking an Internal Thread - The invention relates to a method for producing and checking a thread arranged in a cylinder head to receive a spark plug. However, the invention also relates to a device for checking the thread introduced into the cylinder head. | 04-24-2014 |
