Abstract: A cam-controlled tube end finishing apparatus includes a cutting bit having multiple cutting faces, a platform supporting the cutting bit adjacent to the end of a rotating hollow tube, and a pair of cam-controlled mechanisms for moving the platform and thereby the cutting bit relative to the end of the rotating tube along a closed polygonal path of travel for severing the tube end. An initial portion of the rotating tube is severed in a direction from the outside to the inside of the tube at an angle to a plane normal to the rotational axis of the tube so as to define an initial cut face on the tube end extending in inclined relation to a plane normal to the rotational axis of the tube. A final portion of the rotating tube is severed in a direction from the inside to the outside of the tube at another angle to a plane normal to the rotational axis of the tube so as to provide a substantially burr-free cut face on the tube end extending in a plane normal to the rotational axis of the tube.

Abstract: This invention describes a machine for the manufacture of small grooves in metal edge inserts typically found on the undersurface of snow skis. The machine produces ice-cutting blades by cutting grooves of approximate uniform depth a constant distance from the edge of the snow ski. With a ski positioned and secured with mounting clamps 21 so that a metal ski edge extends beyond a machine platten 10, a plurality of flattening clamps 23 flatten the typically bowed ski against a flat undersurface 22 of the machine platten 10. A cutting tool on a tool holder slidably mounted to a slide means on the platten upper surface then cuts into the metal ski edge following the curvature of the ski edge as it traverses the ski.

The assembly comprises a locking component which contains a bore with at least one recess therein. The assembly also includes a tool holding component with a shank whereby the bore receives the shank. The shank contains a compartment with a locking assembly within the compartment. The locking assembly includes at least one locking member and a positioner assembly that selectively positions the locking member into engagement with its corresponding recess. The recess corresponds to the shape of the locking member such that when the locking member engages the recess, the recess restrains the locking member so that there is essentially no movement between the holder component and the locking component during a material removal operation.

Abstract: A tool is described for boring spherically curved inner surfaces consisting of a main body which rotates about its longitudinal axis during the boring operation. A swivel housing is mounted on an axle bolt in the main body and can thus be swiveled about an axis at right angles to the longitudinal axis. The swivel motion is produced with the aid of a linkage arrangement provided in the tool. A cutting tool holder is guided for longitudinal displacement in the swivel housing at right angles to the axle bolt. The cutting tool holder is supported lateral wedge surfaces on a mating wedge surface of the axle bolt and extends with a shank part through the axle bolt. With the aid of a compression spring and an adjusting screw, the axle bolt can be displaced in the longitudinal direction relative to the cutting tool holder to adjust the radial spacing of the cutter from the axle bolt by the mating wedge surface.

Abstract: A machining unit, in particular in a numerically controlled lathe, has a rotary head equipped with four pivoting tools for machining parts which pass axially through this head without rotating. Each tool is mounted on a respective pivoting support (6a-6d) provided with a helicoidal guiding surface (26a-26d) the axis of which coincides with the pivoting axis (7a-7d) of the support. The four tools are controlled by means of two concentric annular sockets (30, 42) controlled in translation. The inner socket (30) has two outer surfaces which rest against the guiding surfaces (26a, 26b) of two of the supports. The guiding surfaces are helixes of opposite pitch, and therefore one of the corresponding tools moves toward the part as the second tool moves away from it. The outer socket (42) controls the other two tools in the same manner.

Abstract: In a composite-machining machine tool for carrying out a turning operation and a machining center operation, a B-axis shaft 13, having a tool spindle head 14 mounted on its front end, is rotatably supported by a Y-axis slide 10, and the B-axis shaft 13 can be indexingly rotated by a B-axis servomotor 22. Clamp pistons 26 are provided in opposed relation to a flange portion 25 of a front end portion 13A of the B-axis shaft, and the clamp pistons 26 are pressed against the flange portion 25 to thereby fix the B-axis shaft at an arbitrary rotational angle position. By doing so, a hobbing tool 29 can be fixed in such a manner that the axis of this hobbing tool can be precisely indexed at a desired angular position with respect to a workpiece W, thereby enabling a hobbing operation.

Abstract: A shank (10) for retaining a tool or touch probe in the socket (S) of a machine tool spindle comprises 6 areas of surface which, in use, bear against the wall of the socket (S). The areas of surface are provided by three balls (34) resiliently supported for movement radial to a shank axis (A) on small flange section (26) (FIG. 2 ) at one end of the shank (10), and three further balls (36) embedded in the other end of the shank (10). As the shank is drawn into the socket (S) the small flange sections (26) deform allowing the balls (34) to move radially inward until the surface of balls (36) engage the wall of the socket (S). A pull-up stud (38), supported on a frusto-conical block (40) is connected to the shank by a plunger (42) and compression spring (46). Retraction of the shank into the socket by pull-up stud (38) against the resilience of the small flange sections (26), causes the plunger ( 42) to compress spring (46) until the block (40) bears firmly against the wall of the socket (S).
