| PROBLEM TO BE SOLVED: To improve work precision by preventing a work from being inclined in relation to a cutting tool caused by work resistance. SOLUTION: In a cutting work machine 10 for performing cutting work of a work (w) while relatively moving a cutting tool 14 in relation to the work (w), the center lines of feed mechanisms 26, 22 for relatively moving the cutting tool 14 in relation to the work (w) coincide with the center line of the cutting tool 14. That is, since the center lines of the feed mechanisms 26, 22 are not deviated from the center line of the cutting tool 14, the work (w) is not inclined in relation to the cutting tool 14 caused by work resistance. | ||||||

| A device for centering a work piece with respect to a centerline of a tool includes a radially-stationary component rigidly secured with respect to the tool such that the radially-stationary component and the tool are concentric. A biasing mechanism is biased away from the radially-stationary component to apply substantially equally-distributed radial force at a periphery of the work piece to thereby center the work piece with respect to the tool. A method of broaching a work piece having an inner and an outer diameter includes machining the outer diameter and then applying circumferentially-distributed radial force to the inner diameter or the outer diameter to thereby center the work piece with respect to a broach tool. After the applying step, the method includes broaching the inner diameter of the work piece using the broach tool. | ||||||

| In a method of processing a female spline of a hub unit for supporting a wheel, a hole 3a which is formed to be cylindrical is provided on a shaft portion 3c of a hub unit 103 before plastically deforming by caulking (or clinching), and after the plastically deforming by caulking (or clinching), a female spline is formed on the hole 3a by semi-dry or dry broaching. The hole 3a which is formed to be cylindrical after plastically deforming by caulking (or clinching) has the form that the size is greater at a portion nearer a portion 3d plastically deforming by caulking (or clinching) of the shaft portion 3c for an estimated amount of contraction caused by the plastically deforming by caulking (or clinching) or the press-fitting of an inner race element. | ||||||
| 11 | Circulating type milling apparatus for milling a lock core keyway | US09379314 | 1999-08-23 | US06178616B2 | 2001-01-30 | Weng-Teh Lin |
| A circulating type milling apparatus for milling a lock core keyway includes a frame with a rotating disc that is intermittently rotated through a pre-determined angle. Lock core seats are equidistantly provided on the rotating disc. A milling disc is mounted to a top plate of the frame and includes cutters, ejecting plate, and detectors mounted thereon. The cutters are lowered to mill a keyway in each lock core. When the cutters are further moved downward and thus disengaged from the lock cores, the rotating disc is rotated by a distance that is equal to a half distance between two adjacent lock core seats such that each lock core seat is in a positioning in alignment with an associated detector yet not in alignment with an associated cutter. When the milling disc is moved upward, the detector checks whether the milled keyway of the lock core meets the required standard. The ejecting plate ejects the finished milled lock core, and a new lock core is fed by a lock core supplying device. | ||||||

| 13 | Method for providing a toolholder body guide for punch presses | US878611 | 1992-05-05 | US5267384A | 1993-12-07 | John W. Teeslink |
| A toolholder guide for punch blocks, turrets, and the like, including a toolholder bore machined to accept an internal sleeve of wear resistant metal sized for reciprocal motion of the toolholder. The sleeve is installed compressed within the bore, and provides a close clearing radius with the body of the toolholder, so that the toolholder is accurately centered and guided. The inside of the sleeve is finally machined in compressed condition using a bore-simulating holding mandrel. The finally machined sleeve is shrunk for final installation into the turret bore using liquid nitrogen. The sleeve is adapted for toolholders having bodies with protruding keys or for toolholders with longitudinal keyway slots. | ||||||

| Two vertically movable carriages are alternately reciprocated. Each carriage holds two broaches positioned at opposite sides of the ways that guide the carriage. In one embodiment workpieces are moved from a magazine between the carriages alternately to work stations beside each carriage. In another embodiment the workpieces are moved between the two broaches in a series of three steps, the first broach acting on a given workpiece during a dwell before the first step and the second broach acting on that workpiece during a dwell after the third step. In yet another embodiment the workpieces are held by a chuck which, between successive broaching strokes, rotates the workpiece about an axis normal to the broaching strokes. | ||||||

| <P>PROBLEM TO BE SOLVED: To provide an inner surface broaching device for broaching with remarkable accuracy in centering of a broach with a PH and a RH by eliminating a clearance between the PH for holding a broach front handle and the broach, and/or eliminating a clearance between a broach rear handle and the RH. <P>SOLUTION: In this inner surface broaching device, a clamp metal 12 having a tapered surface 44 for complementing an accurate tapered part 81 provided in a front handle of the broach 8 is fixed to a PH main body 11. The broach 8 and the PH are strongly unified by pushing a front handle of the broach 8 to the tapered surface 44 of the clamp metal 12 of the PH, and clamping. <P>COPYRIGHT: (C)2004,JPO&NCIPI | ||||||

| <P>PROBLEM TO BE SOLVED: To provide a female spline forming method of a hub unit for supporting a wheel which is capable of forming a female spline with high accuracy irrespective of the length of the female spline without using any tool in a caulking step, and omitting a cleaning step after the forming. <P>SOLUTION: A hole 3a in a cylindrical shape after caulking is formed in a shaft portion 3c of a hub unit 103, and a female spline is formed in the hole 3a by semi-dry or dry-broaching after caulking. The hole 3a in a cylindrical shape after caulking is set to be larger by the quantity expecting the shrinkage caused by caulking or press-fitting of an inner ring element as the shaft portion 3c approaches a caulking part 3d. <P>COPYRIGHT: (C)2004,JPO&NCIPI | ||||||
