摘要： An improved boring tool with a hollow boring bar and has an exterior semicircular surface and an opposite eliptical surface over a substantial portion of its length and has a circular slotted end portion, the diameter of which is sufficiently small to pass through the neck opening in the workpiece whose interior is to be machined, a piston having its rod extending through the boring bar and connecting to a linkage which also connects to a tool holder which is pivotally mounted to the enlarged slotted end of the boring bar so that the tool holder may be pivoted to position the tool secured to the tool holder for the boring of the arcuate interior surface immediately inside the neck of the workpiece responsive to axial and radial movement of the boring bar in the opening of the neck.

摘要： For drilling a hole and machining at least its opening end without changing tools, a through-hole is drilled using a special tool, and then the same tool is moved sideways by means of a special chuck which guides the tool during machining of the drilled hole. The chuck has a locking device which when engaged holds it in a drilling position and which when disengaged allows sideways motion of a tool mounted in the chuck. The longitudinal section of the tool used, to be located within the hole during the machining operation, is situated within a curved surface having a radius just as great as that of the drill and having its center of curvature on the line about which the tool rotates during drilling.

摘要： A retractable rotary cutting tool is disclosed in which the tool is adapted to be connected to a chuck or a tool holder of a machine tool such as an automobile tool changer on a numerically controlled machining center or the like. The cutting tool support is arranged to have a cutter which is recessed into the support and is pivotally connected to an actuating shaft coaxially within the tool support, which shaft reciprocates relative to the tool support when a thrust collar located about the tool support engages the work or another fixed external surface and will withdraw when the thrust collar engages for a second time an external surface or the work.

摘要： A spot facing tool is mounted on a work table with an arbor located beneath the work table and movable upwardly through an opening in the work table. A cutter holder is mounted on the surface of the work table with a cutter receptacle positioned in alignment with the arbor. A cutter is releasably retained in the receptacle. The arbor is movable upwardly through the opening of a work piece and into the cutter, and connected to the cutter. The cutter and arbor are moved downwardly until the cutter engages the work piece and rotation of the cutter and arbor causes spot facing of the work piece about its opening.

摘要： This invention pertains to a back spot facing tool whose cutting blade is pivotally mounted on a spindle body and is axially actuated by a plunger rod so as to be moved to either a cutting or a concealed condition in response to either a manual manipulation or to a hydraulic actuation of this rod. The back spot facing cutting blade is mounted with its retaining pivot point offset so that one side of the blade in a cutting condition extends a greater distance from the spindle body causing a greater pressure to be exerted on this blade cutting portion than on the opposite side blade cutting portion. The blade portion developing the greater pressure is supported by an adjustable set screw which is adjusted to provide means to establish the exact face angle of back spot face cutting desired by the tool. A precise grinding fixture is also disclosed and carries the blade at a determined condition to its support surface so as to establish the desired cutting blade angles.
摘要翻译：本发明涉及一种背面工具，其切割刀片可枢转地安装在心轴主体上并且由柱塞杆轴向致动，以便响应于手动操作或者手动操作而移动到切割或隐蔽状态该杆的液压致动。背面切割刀片安装有保持枢轴点偏移，使得刀片在切割状态下的一侧从主轴体延伸更大的距离，从而在该刀片切割部分上施加更大的压力，而不是在相对侧刀片切割部分。显影较大压力的叶片部分由可调节的固定螺丝支撑，该可调定位螺钉被调节以提供用于建立工具所期望的背面切割的精确面角的装置。还公开了一种精确的研磨夹具，并将刀片以确定的状态运送到其支撑表面，以便建立所需的切割刀片角度。
