  • Patent number: 8991381
    Abstract: The present invention provides a method of cutting a workpiece efficiently with high accuracy by utilizing tension adjusters to approximate tension in a wire in a wire saw to a predetermined target tension while effectively reducing only tension in a winder-side wire. The method comprises a forward-driven cutting step of cutting a workpiece while moving a wire forward, a first switching step of reversing a driving direction of the wire, a backward-driven cutting step of cutting the workpiece while moving the wire backward, and a second switching step of reversing a driving direction of the wire and returning to the forward-driven cutting step, the steps being repeated in this order. In both switching steps, only tension in a winder-side wire is reduced by tension manipulators. A reduction in target wire tension therefor is performed after completion of deceleration of the wire in each switching step.

  • Publication number: 20150044944
    Abstract: The present invention provides a surface processing system for a work piece in the mechanical technical field. The system comprises at least one group of polishing units. A manipulator and several polishers with different polishing precisions are provided on the polishing units. The polishers are arranged around the manipulator in turn. The work piece could be moved by the manipulator between the processing center and the polishing units. The machined work piece is loaded by the manipulator for one time when the manipulator is located at the processing center. When the manipulator is located at the polishing units, the manipulator keeps holding the work piece and transfers the work piece in a preset sequence to each polisher corresponding to the polishing unit where the manipulator is located. The surface of work pieces having different wall thicknesses and complex surfaces could be processed in a large batch with a high efficiency.

    Abstract: Method and apparatus for sharpening a cutting tool. In some embodiments, an abrasive endless belt is rotated in tension along a neutral plane between spaced apart first and second rollers. A guide assembly has spaced apart first and second guide surfaces which collectively converge to an intervening base surface to form a guide channel. Upon insertion of a blade of a cutting tool into the guide channel, a selected side of the blade contactingly slides against at least a selected one of the first or second guide surfaces and a first portion of a cutting edge of the blade contactingly engages the base surface to serve as a plunge depth limit stop for the blade. The endless belt is contactingly deflected by a second portion of the cutting edge away from the neutral plane to sharpen the second portion while the first portion remains in contact with the base surface.

  • Patent number: 7803037
    Abstract: A multi-head centerless belt grinder for removing material from a workpiece includes a common base and a plurality of grinding heads spaced apart from one another and mounted to the common base. Each grinding head includes a moveable work rest blade, a moveable regulating wheel and a moveable grinding belt positioned by servomotors to centerless grind the workpiece along a common axis of rotation. The grinder is programmable for rapid machine changeover and set-up typically within 2-5 minutes to accommodate a large range of workpiece diameters. This feature results in improved productivity and output as well as greater flexibility for scheduling numerous workpiece diameters within a normal eight-hour work shift. A trough may extend beneath and between each of the grinding heads to more efficiently collect and transfer grinding swarf generated during the grinding process to a filter operable to separate solids within the swarf from coolant.

    Abstract: A dust collection device for a sanding machine includes a casing located at the lower end of the upright sanding belt and the casing includes a bottom hole which communicates with the open top of the dust collection part. The dust collection part communicates with an exterior collection area defined within an outer cover. A fan unit an a separation plate are located within the outer cover, so that dust during operation of the sanding belt can be collected into the exterior collection area and brought out via an escape pipe connected to the outer cover. A sanding wheel is located beside the separation plate and a housing is mounted to the sanding wheel. The housing includes a restriction plate so as to guide dust during operation of the sanding wheel into the escape pipe. The sanding belt, the fan unit and the sanding wheel share a common axle.

  • Patent number: 7704127
    Abstract: A plating layer 18 of Ni or the like is formed around the outer peripheral face 14 of a wire tool 10, and super abrasive grains 16 are electrodeposited so as to be embedded in the plating layer 18. A coating layer 20 is formed on the surface of the super abrasive grains 16 to increase efficiency during electrodeposition. The thickness of the coating layer 20 formed on the super abrasive grains 16 is less than 0.1 ?m, and preferably not more than 0.05 ?m. The coating layer 20 is thin enough that its mass is less than 10% of the mass of the super abrasive grain 16. Accordingly, the super abrasive grains 16 are electrodeposited in a single layer around the outer peripheral face 14 of the core wire 12. As a result, the super abrasive grains 16 do not readily come off the core wire 12, which means that the wire tool will have a longer life. Also, since there is no need to remove any excess super abrasive grains after their electrodeposition, manufacturing costs can be cut and less work is entailed.
