摘要： A method of machining a screw is provided that is capable of preventing formation of a protruding section at a thread tip section. A thread is formed by cutting on a cylindrical body, and a surface of the thread is plastically deformed by rolling. Because of the cutting, a width between-side surfaces of a thread tip section is in a narrowed state as compared to a normal width. This width is narrowed toward a tip of the thread while a thread body section has a width expanded as compared to a normal width. Consequently, the side surfaces are formed to bulge by an excess thickness portion as compared to normal side surfaces. The rolling plastically deforms both side surfaces to cause the excess thickness portion to plastically flow toward the side surfaces.

摘要： A bone plate system for internal fixation of bone fractures includes a bone plate having a plurality of bone plate holes. The holes are constructed to receive either a non-locking, locking, or variable-angle locking bone screw. The holes have discrete columns of teeth or thread segments arranged around the inner surface of the hole for engaging threads on the heads of locking and variable-angle locking bone screws. Conventional locking bone screws engage the bone plate coaxially with the central axis of the bone plate hole. Variable-angle locking bone screws can engage the bone plate at a selectable angle within a range of selectable angles relative to the central axis of the bone plate hole. The head of the variable-angle locking screw is at least partially spherical, and the thread thereon has a profile that follows the arc-shaped radius of curvature of the spherical portion of the screwhead.

摘要： The present invention prevents the occurrence of variation in the lead of a threaded section of a machined article (19a) resulting from the effects of thermal expansion of the machined article (19a) during machining. A thermal expansion amount that relates to the axial direction of the machined article (19a) during machining is measured by measurement means (13), history information for the thermal expansion amount that relates to the machined article (19a) during machining is obtained from the result of the aforementioned measurement, and a control unit (17a) determines the relative rotational speed of a rotary drive shaft (11) or the feeding speed of an axial feeding device (16a) with respect to the next machined object (19a) that is to be machined on the basis of the history information for the thermal expansion amount of the machined object (19a) that has been machined.

摘要： The present invention is a systematic displacement bone screw having minor and major thread diameters that are constant instead of tapered. The crests at the tip of the screw are narrower than the crests near the screw head resulting in a smaller distance between the thread flanks, which displaces and/or compresses more bone matter. Because the major diameter remains constant, the diameter of the hole made by inserting the screw is consistent over the length of the screw allowing the screw to be adjusted without loosening. The systematic displacement screw with varying crest thicknesses also avoids the need to use a larger diameter screw in place of a removed screw during a repair procedure. Rather than increasing the size of the hole, the systematic displacement screw can be used for the both the original screw and the replacement screw.
摘要翻译： 本发明是一种系统性位移骨螺钉，其具有常数而不是锥形的小直径和大螺纹直径。 螺钉尖端的顶部比螺钉头附近的波峰窄，导致螺纹齿侧之间的距离更小，这样就移位和/或压缩更多的骨骼物质。 由于大直径保持恒定，通过插入螺钉所形成的孔的直径在螺杆长度上是一致的，允许调节螺丝而不松动。 具有不同波峰厚度的系统位移螺钉也避免了在维修过程中需要使用较大直径的螺钉来代替去除的螺钉。 而不是增加孔的尺寸，系统的位移螺钉可用于原始螺钉和替换螺钉。

摘要： A threading control method and apparatus therefor is provided, in which, when carrying out thread-cut machining operations several times at one position, synchronized with main-spindle rotation and controlling movement of a threading spindle, deviations in thread grooves are prevented without correcting programmed commands, machining accuracy is improved, and tool life extended.When a main-spindle single-rotation reference signal and a main-spindle position counter are input to the numerical control apparatus, the present main-spindle position is computed by a main-spindle position computing means 103, the difference between the main-spindle single-rotation reference signal and control cycles is obtained, as a correction amount 108, from the computed main-spindle position, by a main-spindle position-correcting means 104 and a correction is done. A threading-spindle interpolation starting detection means 105 monitors whether the main-spindle single-rotation reference signal and the control cycles are synchronous, and when synchronous, interpolation for the threading spindle is started by interpolation means 106 for each spindle.
