Including Means To Support Work For Rotation During Operation Patents (Class 409/165)
  • Patent number: 9575485
    Abstract: A method of machining a workpiece may include continuously rotating the workpiece, continuously rotating a tool having at least one cutting surface, and positioning the tool relative to the workpiece so that the at least one cutting surface engages the workpiece at a first discrete location at a periphery of the workpiece. The method may further include continuing to rotate the workpiece and the tool so that the at least one cutting surface engages a second discrete location at the periphery of the workpiece, and controlling a tool surface velocity VT relative to the workpiece surface velocity VW so that the first and second discrete locations are discontinuous. The tool may make multiple iterative passes over the workpiece to engage subsequent discrete locations, wherein the first discrete location, second discrete location, and multiple subsequent discrete locations may form a machined surface that extends continuously around the workpiece.

  • Patent number: 7434299
    Abstract: Methods for manufacturing high precision arrays of curved features (e.g. lenses) in the surface of a workpiece are described utilizing orthogonal sets of inter-fitting locating grooves to mate a workpiece to a workpiece holder mounted to the spindle face of a rotating machine tool. The matching inter-fitting groove sets in the workpiece and the chuck allow precisely and non-kinematically indexing the workpiece to locations defined in two orthogonal directions perpendicular to the turning axis of the machine tool. At each location on the workpiece a curved feature can then be on-center machined to create arrays of curved features on the workpiece. The averaging effect of the corresponding sets of inter-fitting grooves provide for precise repeatability in determining, the relative locations of the centers of each of the curved features in an array of curved features.

  • Patent number: 7201546
    Abstract: When a rotary table rotates, a main control section of a multi-tasking machine detects vibration of the rotary table on which a workpiece is mounted based on fluctuation of a position droop computed by a servo system. The main control section computes the arrangement position (the eccentricity amount and the eccentricity angle) of the workpiece with respect to the rotary table based on, for example, the detected vibration, the weight of the workpiece, and the rotation speed of the rotary table. The main control section computes the attachment position of a balancer with respect to the rotary table based on the computed arrangement position of the workpiece. Therefore, a suitable attachment position of a vibration suppressing balancer with respect to the rotary table is easily obtained.

  • Patent number: 7155788
    Abstract: A C-axis driving device of a computer numerical controlled (CNC) lathing and milling machine includes a spindle, an encoder, a spindle motor, and a servo motor. The spindle has a clamping device and a transmission portion. This encoder connects with the transmission portion via an auxiliary timing belt. The spindle motor and the servo motor connect with the transmission portion via at least one driving timing belt. Only at most one of the spindle motor and the servo motor is to drive this transmission portion at any time during operation. So, it has a simple structure to achieve the clutching change function. It can save more space. And, it can significantly reduce the manufacturing cost.

  • Patent number: 6994001
    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.
