摘要： A ballscrew thread forming tap including a complete thread portion and a leading portion is to be screwed into a prepared hole provided in a workpiece so as to cause an inner circumferential surface of the prepared hole to be plastically deformed for thereby forming a ballscrew thread corresponding to an external thread provided in the complete thread portion. A screw thread of the external thread has a leading flank and a trailing flank, which are to be positioned on a front side of the trailing flank and on a rear side of the leading flank, respectively, when the ballscrew thread forming tap is screwed into the prepared hole. The screw thread is formed such that, in the leading portion, an indentation depth into the workpiece made by the leading flank is smaller than an indentation depth into the workpiece made by the trailing flank.

摘要： A tap phase detection method includes: acquiring a relation between a rotation angle and an existence of a screw thread by measuring a position of the screw thread of a tap with a sensor from a direction intersecting with an axial direction of the tap while rotating the tap; and detecting a phase of the tap based on the acquired relation between the rotation angle and the existence of the screw thread.

摘要： A tap and chaser are provided each having a cylindrical tool receiver connected to a threading section by a shaft. The receiver and shaft are of diameters sufficiently small to enter the bore hole and distribute any off axis load onto a number of internal threads of the bore hole to dissipate loading. The threaded section includes a group of longitudinal flutes. Each of the lands of the threaded section includes a novel cutting face, tooth angle and rake angle to advantageously allow for threading deep blind holes.

摘要： A hybrid threading tap includes a reamer portion and a thread cutting portion having a plurality of cutting teeth. The thread cutting portion is arranged with the reamer portion along the longitudinal axis. The reamer portion is configured to be advanced within a hole of a workpiece to plastically deform and expand the hole to an expanded hole and provide the expanded hole with a zone of residual compressive stress. The plurality of cutting teeth is configured to cut a threading into the expanded hole within the zone.

摘要： A concrete float, float assembly, float adapter and interface, and vibration apparatus and methods are described. A vibration assembly has at least first and second interface components, and for example one interface component can join with an interface component on a pivot assembly and another interface component can join with an interface component on a finishing tool. An interface such as may be included in a quick attach/release configuration may be integrated on vibration apparatus and/or on a pivot assembly for quick attach/release of a joining component. A vibration assembly may include a load transmission or transfer component for transferring a load through the vibration assembly. A pivot assembly may include first and second interface components.

摘要： The invention relates to a method of making a thread or tap on a cylindrical, conical or frustoconical piece to be machined.
According to the invention, this method comprises the steps of: a) driving in rotation the piece to be machined in one direction), b) carrying out a relative displacement of a first cutting edge of a tool relative to the piece to be machined until this first cutting edge is flush with the surface to be threaded of the workpiece at the beginning of the section to be threaded, c) carrying out a relative displacement of the tool relative to the piece to be machined so that the first cutting edge machines the piece to be machined, d) carrying out a relative displacement of the tool along the longitudinal axis of the piece to be machined, in one direction until the end of the section to be threaded, e) moving away, by a relative displacement, the first cutting edge of the tool from the piece to be machined, and it has the particularity of further comprising the steps of: f) reversing the rotation of the piece to be machined to drive this piece in rotation in the direction opposite to the direction, while positioning or not the second cutting edge, g) moving, by relative displacement, a second cutting edge towards the piece to be machined until this second cutting edge penetrates the thread pitch, h) carrying out a relative displacement of the second cutting edge relative to the workpiece so that it continues the machining of the thread in the piece to be machined, i) carrying out a relative displacement of the second cutting edge in a direction opposite to the direction, until the beginning of the section to be threaded, j) moving, by a relative displacement, the second cutting edge away from the workpiece to be machined, k) reversing the rotation of the piece to be machined, while positioning or not the first cutting edge then l) repeating steps b) to k), while continuing the machining of the thread, until the thread reaches its final dimensions, while positioning the first cutting edge in step b) in such a way that it penetrates the thread pitch already machined.
