摘要： Provided is a hole drilling machine and the method for drilling an oval hole and an inner-diameter-changing hole by means of the hole drilling machine, the machine and the method being configured so that the oval hole can be shaped with high accuracy and drilling of a complicated hole such as the inner-diameter-changing hole can be performed with high accuracy. A hole drilling machine 100 includes a spindle 101 and an auxiliary spindle 120 holding both end portions of a processing tool 102 having a cutting blade 103. The spindle 101 includes a spindle drive motor 106 configured to rotatably displace the processing tool 102 on a circular path, and a tool turnable-drive motor 105 configured to spin the processing tool 102. The auxiliary spindle 120 includes an auxiliary spindle drive motor 120b. In the auxiliary spindle drive motor 120b, a tool fitting portion 120a in which a tip end portion of the processing tool 102 is slidably fitted is synchronously rotatably driven on the same circular path as that for the spindle 101. A table reciprocatably-displacing mechanism 111 is provided between the spindle 101 and the auxiliary spindle 120. The table reciprocatably-displacing mechanism 111 reciprocatably displaces a work piece WK in an X-axis direction perpendicular to an axial direction of the spindle 101.

摘要： In a first embodiment, at a time of magnetic pulse welding, a stepped tube profile machining process axially bores a walled tube from an end inward to a transition depth to form a section with a reduced wall thickness and then axially bores the walled tube from the transition depth to a fall off depth, thereby forming a section with a maximized welding wall section. In a second embodiment, also at a time of magnetic pulse welding, a surface angle tube profile machining process axially bores at a surface angle a walled tube from an end to a bore length to form an angular welding wall thickness inward to a maximized wall section. For both embodiments, the bored surfaces are virgin with no pits, oil, residue, or oxidation thereon, thus making the machined walled tubes available for immediate magnetic pulse welding.
摘要翻译：在第一实施例中，在磁脉冲焊接时，阶梯式管型材加工工艺从一端向内轴向地将一个管壁从内向内延伸至过渡深度，以形成具有减小的壁厚的部分，然后将壁管从过渡深度达到脱落深度，从而形成具有最大化的焊接壁部分的部分。在第二实施例中，也是在磁脉冲焊接时，表面角管型材加工工艺以从一端到一孔的表面角度以一壁面管的方式轴孔地形成一个角焊接壁厚度向内到最大壁部分。对于两个实施例，钻孔表面是原始的，没有凹坑，油，残余物或氧化，因此使加工的壁管可用于立即磁脉冲焊接。

摘要： The invention relates to a method of and apparatus for making an undercut in a drilled hole in a fixed base, such as concrete, masonry or the like. The shank of a milling cutter is supported and held eccentrically in the drill hole by means of a supporting sleeve which can be extended into the drill hole when the milling cutter is running. The supporting sleeve has an outside diameter slightly less than the diameter of the cylindrical drill hole so as to fit therein, and is formed with a receptacle groove extending longitudinally of the sleeve and opening at the periphery of the sleeve. The shank of the milling cutter is positioned in the groove, the axis of which is parallel to but radially outwardly spaced from the coaxial axes of the drill hole and sleeve. Rotation of the sleeve can be by a hand wheel interconnected to the sleeve, with the milling cutter rotating with the sleeve to form the undercut.

摘要： A bit assembly for undercutting a blind bore extending along a bore axis between an open outer end and a closed inner end and having a substantially cylindrical wall of a predetermned diameter centered on the bore axis and extending between the ends comprises a pusher body normally seated in the closed inner end of the bore and having an outwardly turned camming surface inclined to the bore axis, and a bit having a shaft extending along a longitudinal bit axis and having an inner end, an outer end, and a pair of longitudinally extending sides terminating at the inner end. One of the sides is at least partially cylindrical and centered on the bit axis and the inner end is formed with a camming surface engageable with the camming surface of the body and inclined to the bit axis. A blade fixed permanently and stationarily on the inner end projects radially from the one side of the shaft, the other side being cut back toward the bit axis.

摘要： A portable slotting device is used to cut a conical slot in a propellant grain of a rocket motor. A telescoping arm having a cutter thereon is mounted at an angle upon a rotating shaft held in position by a housing attached to said motor. Pressurized fluid is fed to the telescoping arm for providing the motive force to extend the cutter. A control cable is attached to one of two extension arms in the telescoping arm and to an adjusting knob. As the drive shaft is rotated, the adjusting knob is unthreaded from a rod having the control cable attached thus allowing the control cable to extend the telescoping arm. The pressurized fluid forces the extension arms out while the control cable restrains movement. The cutter thus moves in a spiraling conical motion paring out propellant grain.

摘要： Apparatus for internally peeling metal tubes includes a peeling head rotatable about a longitudinal axis. An elongated cutter holder having opposite end portions is mounted on the head and extends generally parallel to the longitudinal axis of the head. One end portion of the cutter holder is mounted to the head by a pivot connection for providing swinging movement of the holder toward and away from the longitudinal axis of the head. Both of the end portions of the cutter holder are also adjustable outwardly and inwardly relative to the longitudinal axis of the head.

摘要： A tapered and curved internal diameter is formed within a tube used as a continuous casting mold by feeding the tube lengthwise along an arc which is tangent to the axis of the spindle of a boring mill having a rotatable boring head arranged within the tube for cutting the interior wall thereof. The boring head and spindle revolve about a fixed axis, but the boring tool or cutter carried by the head is gradually moved transversely of the spindle axis while the tube is advanced along the arcuate path. Thus, the opening within the tube is tapered from one end to the other, and is also curved, wherein the tube is useful as a continuous casting mold and the like.

摘要： A boring bar has a free end that extends beyond the boring tool and has a guide roller rotatably mounted on the free end about an axis which is parallel to and offset from the boring bar axis. A guide bushing is supported in concentric alignment with the free end of the boring bar and rollably engages the guide roller at a point whose radius with respect to the boring bar axis extends in the same direction as the boring tool. The boring bar is preferably necked down between its supported end and the boring tool to facilitate deflection of the boring bar in response to pressure applied to the free end thereof by the guide roller and guide bushing.
