With a total of 11 patents to his name, Shibata has made significant advancements in the technology that enhances the precision and efficiency of machining processes.
Latest Patents
Among his latest patents is the "Wire electrode feeder for wirecut electrical discharge machine." This invention features a wire electrical feeding device designed for an electrical discharge machine. It utilizes vibrator assemblies to feed the wire electrode through electrode guides. A first vibrator assembly vibrates in a direction that includes a component in the wire feeding direction. The wire electrode is selectively pressed against this assembly during its movement. Alternatively, a second vibrator assembly, coupled to the first, clamps the wire electrode when the first assembly moves in the wire feeding direction. Notably, these vibrator assemblies can be driven at different vibrational frequencies.
Another significant patent is the "Wire cut electric discharge machining apparatus." This apparatus is capable of machining a workpiece using a machining solution to produce a desired shape. The workpiece is magnetically attracted and held in place by one of a pair of nozzles that supply the machining solution to the interelectrode gap between the workpiece and a wire-shaped electrode. The controlled attraction condition allows for high accuracy and safety in moving and conveying the workpiece to the desired position.
