    Abstract: A lathe attachment device is disclosed for producing long articles with complicated profiles. The device contains a beveled multi-teeth cutter driven to rotate in a direction opposite the rotation of a billet to ensure a very short period of contact time between an individual cutting tooth and the article. The cutter is slightly tilted towards the billet in both horizontal and vertical plane. The teeth of the cutter are shaped to each have a pointed end facing the rough part of the billet. Provisions are made to draw the cutter along the billet. The device allows producing a smooth finished long article with complicated surface profile in a single pass with high productivity. Due to limited contact time, it offers extended life of the cutter. The device is used most advantageously to produce long wood articles.

    Abstract: A method of machining seats of a compressor piston having an approximately hemispherical recess. A surface of a piston extending perpendicular to an axis of the piston is machined by annularly moving a cutting element while the cutting element is rotated with respect to the piston to form an annularly cut portion. The surface is further machined by moving the same cutting element in a direction toward the surface while the cutting element and the piston are relatively rotated to form a hemispherical recess in the surface. The firstly formed annularly cut portion becomes an annular chamfered portion on the periphery of the hemispherical recess. In this way, it is possible to form the hemispherical recess, and the annular chamfered portion on the periphery thereof, with the common cutting tool.

    Abstract: A spoked wheel rim having a hub defining an axis, a plurality of spokes projecting radially from the hub, and a rim ring attached to outer ends of the spokes is machined by first mounting it in a loading/unloading station into a holder rotatable about a holder axis with the rim axis generally coaxial with the holder axis. Then the holder is orbited by a turntable carrying the holder from the loading/unloading station into a working station angularly offset relative to the loading/unloading station about a turntable axis between the stations. A rotating tool is then displaced by means of a head carried on a hexapod positioner at least over surfaces of the spokes while holding the rim stationary in the working station to machine the surfaces. The rim is then continuously rotated about the holder axis in the working station while engaging a rotating tool carried on the hexapod positioner with an edge of the rim ring to machine the edge.

  • Patent number: 6026549
    Abstract: A crankshaft phase indexing apparatus of this invention is provided with a pair of spindles arranged in alignment with a first axis. The Spindles are rotated respectively by a pair of spindle driving motors, which are controlled to rotate at the same speed. Chucks are mounted to the respective spindles. The chucks hold ends of a crankshaft in alignment with a second axis, which is displaced from and parallel to the first axis. A phase conversion shaft is rotatably arranged in at least one of the chucks in alignment with the second axis. The phase conversion shaft is connected to the crankshaft for rotating the crankshaft to permit phase indexing of crankpins of the crankshaft into axial alignment with the first axis. A phase indexing shaft, which is coupled to the phase conversion shaft, is located concentrically with the spindles and is rotated by a phase indexing motor.

  • Patent number: 5938381
    Abstract: A method for creation of a surface from a rough blank for spectacles is which is suitable for both brittle-hard materials and for plastics uses makes use of a disk-shaped, rotation-symmetrical tool of relatively large diameter, by means of which the material to be taken off the rough blank is removed with high grinding or milling efficiency in at least two work steps--a plunge-cut step and a shaping step with material removed along a spiral path. The outcome of the last work step is a machining path traveling in a spiral from the outside to the inside with low residual apex height and relatively large apex spacing. The resulting surface needs only slight fine-grinding and polishing aftertreatment. As an option, both a rim machining step adapted to the form of the eyeglass frame and a work step faceting the rim of the eyeglasses can be integrated into the method. Furthermore, tools are proposed for carrying out the grinding and milling process.

  • Patent number: 5927166
    Abstract: In a plural-roll rolling mill having a pass line arranged by the respective sets of rolls, each having a caliber formed on the outside peripheral surface thereof, the outside peripheral surfaces being disposed close to each other, the calibers of the rolls being cut with a cutting tool of a three-dimensionally (forward and rearward, rightward and leftward and upward and downward) movable cutting machine. The rolling mill, which has a reference column disposed on the outside surface thereof at a position spaced apart from the pass line by a predetermined distance, is removed from a rolling line and fixed, and the positional alignment of the cutting tool is carried out by causing a contact sensor disposed on the cutting machine at a position spaced apart from the cutting tool by a predetermined distance to come into contact with the reference column. With this arrangement, there are provided a method and apparatus capable of cutting the rolls of the plural-roll rolling mill while mounted on the rolling mill.

  • Patent number: 5823721
    Abstract: The invention relates to a method of producing concave, self-contained bearing surfaces, which are at least part of spherical indentations which extend beyond the sphere equator, by means of machining involving the removal of material of pre-formed indentations in workpieces by means of a tool having a tool cutting edge orbiting around a tool axis of rotation with an orbit diameter which is equal to the length of a chord extending up to a deepest point of the bearing surface, whereby the cutting movement is made up of the orbital movement of the tool cutting edge and a rotational relative movement between workpiece and tool around a vertical axis through the sphere center, and the feed movement is a movement of the tool relative to the workpiece along the tool axis of rotation which is obliquely set at the same angle of inclination relative to the vertical axis as is the chord set to the sphere equator.
