    Abstract: The invention relates to a threading machine having a rotating threading head (1) that can be displaced in the direction of the axis of rotation (1a). Said device also has tool sliders (3a, 3b) disposed in pairs opposite each other and radially displaceable in relation to the axis of rotation, said sliders having tools (13, 14). Said device further includes a drive organ (2) rotating along with the threading head and displaceable in the direction of the axis of rotation. A movement of said drive organ in relation to the threading head in the direction of the axis of rotation brings about a radial movement of the tool slider.

    Abstract: A vibration assisted tapping device includes an elastic frame for translating axial vibration to a vibration having both axial and torsional components. The elastic frame has flexural members that connect an upper plate to a lower plate with a vibratory actuator preloaded therebetween. The flexural members are inclined relative to an axis of the frame in a direction calculated to result in translated vibration substantially aligned with the lead angle of the thread being cut. Also disclosed is an automated system for applying different vibration patterns to the tap/workpiece interface during tapping and for recording the tapping torque associated with each vibration pattern. The disclosed system permits identification of the vibration frequency and amplitude that results in the greatest reduction in tapping torque. The automated system may be configured as an adaptive machine tool to first identify and then apply the optimum vibration pattern.

A face gear (220) has at least the locking jaws (230) disposed in a slot (225) provided on the face of the face gear oriented away from the housing (310). The mechanism also comprises a drive ring (270) having a collection of cam profiles (276) to control the movement of the locking jaws (230). The mechanism also comprises at least one compression spring (250) disposed in a corresponding groove (222) on the face gear (220). The compression spring (250) is preloaded to keep the locking jaws (230) in a locked position. The mechanism also comprises a bearing (240) between the housing (310) and the face gear (220). The bearing (240) is locked in place by a retaining ring (260). A locking plate (280), spring washers (290), and screws (294) are used to secure the assembly of the die head retaining mechanism on the power drive (300).

    Abstract:  チップ(14)に設けられたねじ軸(24)がボデー(12)に設けられたねじ穴(26)に螺合されることにより、チップ(14)がボデー(12)に着脱可能に取り付けられるとともに、ボデー(12)に設けられた拘束穴(38)内にチップ(14)の拘束部(40)が嵌合されて、ボデー(12)とチップ(14)とが軸心Oと同心に位置決めされる。これにより、別体の取付ねじが不要となり、ボデー(12)およびチップ(14)の2部品で構成されるため、高い心出し精度が得られ易いとともに、各部品の断面積が大きくなって強度が高くなり、工具寿命のばらつきが抑制されて優れた工具寿命が安定して得られるようになる。また、ねじ軸(24)の先端面(24f)がねじ穴(26)の底面(26f)に密着するように押圧されて、チップ(14)がボデー(12)に一体的に固定されるため、ねじ軸(24)には圧縮応力が作用するようになり、引張応力が作用する場合に比較して高い締結強度でチップ(14)をボデー(12)に締結できる。

The cycle machining device further has a position command value output unit (103) which outputs the position command values of the X-axis and U-axis synchronously with the C-axis at the time of actual machining, X-axis and U-axis position deviation calculating units (110, 120) which calculate the respective position deviations, X-axis and U-axis learning control unit (111, 121) which learn correction command values with which the respective position deviations are reduced to zero, store them, and output them synchronously with the C-axis, and X-axis and U-axis adding units (112, 122) by which the correction command values and position deviations of the respective axes are added to each other, and the addition results are outputted as speed commands to the inner surface and outer surface machining driving means.
